Danger: Diabolik

Plot

In an unidentified European country, Police Inspector Ginko oversees the transportation of $10 million from a bank. To prevent the master thief Diabolik from stealing the money, he creates a diversion whereby a truck from the bank transports wastepaper, while a team of himself and disguised officers take the money in a Rolls-Royce. The plan is still foiled by Diabolik, who escapes with the money and his lover Eva Kant to their underground hideout, where they have sex on top of their loot.

Diabolik and Eva attend a press conference held by the Minister of the Interior, who reinstates the death penalty to dissuade criminals such as themselves; they disrupt the conference by releasing exhilarating gas into the crowd. Unable to locate Diabolik, Ginko and his fellow officers are granted emergency privileges that allow them to crack down on the activities of gangster Ralph Valmont, who they hope will aid in capturing him. Realizing their plan after a teen discotheque he operates is raided due to it being a front for his drug trafficking operations, Valmont makes a deal with Ginko.

While watching a news report, Diabolik decides to steal the famous Aksand emerald necklace from the Château de Saint-Just for Eva's birthday. After learning of Eva's features from a prostitute who spotted her scouting the castle, Valmont builds and circulates an identikit image of her. Diabolik scales the castle's sheer walls as the police lie in wait, and steals the necklace. Driving on his getaway, he and Eva fool the police by pulling a mirrored film across the road and using dummy decoys of himself; Eva is injured while setting up the film.

While visiting her private doctor, Eva is recognized from the identikit image and abducted. To rescue her, Diabolik boards Valmont's airplane with the stolen $10 million and the necklace to trade for Eva. He is ejected from the plane, but manages to grab Valmont just before a bomb he had planted earlier explodes. Diabolik rescues Eva as Ginko and the police close in on them. Eva makes her escape, while Diabolik loads a gun magazine with the emeralds and fires them at Valmont, killing him. He then seemingly commits suicide by taking a mysterious capsule. As the police hold a press conference about Diabolik's death, he is about to be autopsied when he returns to life, having faked his death using a technique created by Tibetan lamas which requires an antidote to be administered within twelve hours; posing as a nurse, Eva administers the antidote and sneaks him past the police and the press.

Production

Development

Angela and Luciana Giussani's Diabolik, widely considered to be the first example of the fumetti neri subgenre of Italian comics, was first published in November 1962. Producer Tonino Cervi, head of the production company Italy Film, was the first person to propose a film adaptation of Diabolik. Cervi was ambiguous when describing his production, stating once that "I think that with a few retouches Diabolik could turn into an extraordinary character for the silver screen." In another interview, he acknowledged that "nowadays a good film based on Flash Gordon would be a sensational success [...] but it would cost as much as Cleopatra. I have to settle for something more modest, so I'm doing Diabolik." Cervi's intention was to use the profits earned from Diabolik to recoup the costs of producing Red Desert and The Moment of Truth, as well as to finance an anthology film directed by Federico Fellini, Ingmar Bergman and Akira Kurosawa.

Italy Film acquired the adaptation rights from Astorina, the Giussanis' publishing house, for 20 million lire and proposed a distribution deal with Dino De Laurentiis. This deal would involve 100 million lire in advance, in exchange for the distribution rights for the film in perpetuity. De Laurentiis advanced 70 million lire, and put together a co-production deal between Italy, France (Les Films Marceau-Cocinor) and Spain (A.S. Film Produccion and Impala); the film's budget would ultimately be set at 501 million lire. The first drafts of the script were written by comic book writers Pier Carpi and Corrado Farina, who also worked in television advertising. These drafts were later revised by screenwriters Giampiero Bona and Fabrizio Onofri, who were told to tone down the violence. Onofri and Bona's screenplay also added an emphasis on comedy that was present in Andre Hunebelle's film Fantômas, another film about a master thief that was popular at the time. Diabolik's arch-nemesis from the comics, Inspector Ginko, was not included in the script as negative depictions of the police in media were a sensitive subject in Italy at the time. The film was helmed by British director Seth Holt, and the cast was led by Jean Sorel as Diabolik, Elsa Martinelli as Eva Kant and George Raft as Richness, an Auric Goldfinger-esque antagonist. Cervi's original choices for Diabolik and Eva had been Alain Delon (whose salary was too high) and Virna Lisi (who was unavailable due to scheduling conflicts), while James Mason, Peter Ustinov, Orson Welles and Gert Fröbe were considered for Richness. Other members of the cast included Marilù Tolo, Venantino Venantini and Jimmy Karoubi.

Principal photography began on 20 September 1965 in Málaga, Spain, but was halted when Raft was replaced with Gilbert Roland. Cervi and Holt's schedule required 29 days of interiors to be shot at De Laurentiis' sound stages at "Dinocittà", 17 days on location in Spain, two weeks on location in the United States, and an additional week in Spain. Filming halted again on 13 November; having viewed Holt's dailies, De Laurentiis temporarily aborted the film's production, stating that the footage "was of a level so low, both from an artistic and commercial point of view, as to make us clearly understand that to continue on that path meant heading toward disaster". In a 1969 interview, Holt said the film "didn't get stopped, it ran out of money. [...] It was mismanaged and so the film came to an end and everybody went home. Everybody is suing everybody. I got paid actually because I knew the Italian scene."

Writing and pre-production

The initial treatment for Danger: Diabolik was written by Adriano Baracco, which was then adapted into a full screenplay by Dino Maiuri, who had previously scripted the Eurospy comedy Kiss the Girls and Make Them Die for De Laurentiis. The script was later revised by the British writing team of Brian Degas and Tudor Gates, who were hired by Bava due to their positive collaboration on the aborted giallo project Cry Nightmare (later filmed by Antonio Margheriti as The Young, the Evil and the Savage). The final screenplay, which is credited to Maiuri, Degas, Gates and Bava in the English version of the film, and only to Maiuri and Bava in the Italian version, was based on three separate Diabolik stories: Sepolto vivo! (transl. Buried Alive!) from August 1963, Lotta disperata (Hopeless Battle) from March 1964, and L'ombra nella notte (The Shadows of Night) from May 1965. Degas and Gates' script bore the working title of Goldstrike! for Paramount to consider as an alternative title for the film's international release due to the fumetti being little known outside Italy; the film's English title was announced by Paramount's publicist Chuck Painter to be Danger: Diabolik on 29 November 1967. De Lautentiis was so enthusiastic towards Degas and Gates' work that he hired them to provide additional material for Barbarella.

In analyzing Degas and Gates' Goldstrike! script (dated 5 December 1966) compared to the film, Bava biographer Tim Lucas notes that the former includes details not featured onscreen, such as Diabolik being implicated as the mastermind behind the 1963 Great Train Robbery (a reference to Julius No's implied theft of Portrait of the Duke of Wellington in Dr. No), sequences that were staged differently to what was filmed, and lacks scenes that were entirely Bava's invention. Among the differences include the opening heist—which was scripted as concerning an armoured car carrying gold, compared to the film's depiction of a diversion in which cash is transported in a Rolls-Royce accompanied by a police motorcade—a police raid on a casino instead of a discotheque, Eva injuring herself while using an exercycle rather than while helping Diabolik set up a trap, a second conversation between the Minister of Finance and Inspector Ginko being substituted with a televised plea to the public, and Eva visiting Diabolik's gold-encased body in the Hall of Ministry rather than in their hideout. Lucas believes that many of Bava's alterations to the screenplay served to make the characters more sympathetic and believable, and notes that many of the film's wittiest and most memorable moments, such as Diabolik and Eva's lovemaking on top of the stolen $10 million (a parody of Horst Buchholz covering Catherine Spaak's nude body with lira notes in The Empty Canvas) and Valmont's threat to "cross [Dr. Vernier] from the human register", were entirely the director's creation.

Casting

John Phillip Law was invited to audition for Diabolik as a favor by De Laurentiis after production on Barbarella, which Law had been cast in as Pygar, was delayed due to technical difficulties, allowing director Roger Vadim and his wife and star, Jane Fonda, to make the "Metzengerstein" segment of Spirits of the Dead. An avid comic book fan since childhood, Law was initially unfamiliar with the characters in Diabolik, and read several of the comics to understand his character, as he had done when preparing for Barbarella. Due to most of the character's face being hidden by a black or white skin-tight mask, Law noted that the most prominent aspect of Diabolik's appearance was his eyebrows; he prepared for the role by applying mascara to his own, and taught himself to convey a wide array of expressions with them. Upon meeting with De Laurentiis and Bava, the director exclaimed "Ah, questo Diabolik!" ("This is Diabolik!"), indicating to Law that he had won the role.

Budgetary changes led to established actors being cast in smaller roles, including Michel Piccoli—who was recommended to De Laurentiis by Vadim—as Ginko, Adolfo Celi as Valmont and Terry-Thomas as the Minister of the Interior (later the Minister of Finance). Because of his busy schedule, which precluded his ability to dub his own performance (in the typical manner of production for Italian films), Terry-Thomas' scenes were shot in a single day and his dialogue was recorded as live sound. Several minor members of the film's cast had appeared in Bava's earlier films, including Federico Boido (Planet of the Vampires), Francesco Mulè (Dr. Goldfoot and the Girl Bombs) and Walter Williams (The Girl Who Knew Too Much). Renzo Palmer, whose character Mr. Hammond usurps Terry-Thomas in the Minister of the Interior role, was also an experienced dubbing actor who had provided voice work for Planet of the Vampires and Knives of the Avenger; for the Italian version of the film, he looped not only his own lines, but those of Terry-Thomas'.

Casting Eva Kant proved particularly troublesome. According to Law, the role was originally going to be played by an unidentified American model who was cast at the behest of her friend, Gulf and Western (the then-parent company of Paramount) President Charles Bluhdorn; Law noted that the model was "gorgeous, but couldn't say 'Hello' on film". Official production documents dated 4 April 1967 note that Laura Devon was eventually cast as Eva, but she was quickly replaced by Catherine Deneuve; Vadim, her ex-fiancé, had recommended Deneuve to De Laurentiis. Law believed that Bava was against this idea, and felt personally that Deneuve was wrong for the role: "There was no chemistry between us. She was very sweet, and a very good actress, but she was simply not right for the part"; he also stated that "Catherine may not have been ready for the part. She had not yet done Belle de Jour. I think if she had done Diabolik after Belle de Jour, she might have been more relaxed, and things might have worked out a little differently." After examining production photographs of Law and Deneuve, Lucas corroborated Law's assessment by noting that the actress was "unable to subdue her own persona to inhabit the character of Eva Kant. Standing beside her clearly enamored co-star in her white vinyl boots and mini-dress, she looks like an Ice Princess to be worshiped—which was not the interpersonal dynamic required between Eva and Diabolik. [...] Her casting would have badly weakened Diabolik's all-important authority and thrown the film completely off-balance." When asked about her involvement in the film in the 1980s, Deneuve revealed that Bava took his frustrations with the film's production and her lack of chemistry with Law out on her, saying, "He didn't seem to find anything about me agreeable, not even the way I walked". After a week of shooting with Deneuve, Bava and De Laurentiis decided that she should be replaced; having objected to the nudity required for the role, she was fired after she refused to perform the scene in which Diabolik and Eva have sex on top of the $10 million they have stolen.

Filming

Danger: Diabolik began filming on 11 April 1967 and was shot at Dinocittà, a Fiat plant in Turin, the Blue Grotto in Capri, and on location in Rome and Anzio. In a 1970 interview with Luigi Cozzi, Bava described the filming as "nightmarish", and said that De Laurentiis had him tone down the violent scenes in the film. Law commented that the producer and director had opposite ideas for the film: De Laurentiis wanted to make a family-friendly film with a charming thief in the vein of Raffles, while Bava wanted to make a film that was faithful to the comic books. Lamberto Bava recalled that while his father's relationship with the producer was generally amiable, he was also frustrated by De Laurentiis' frequent absences due to his commitments to other films. Danger: Diabolik finished filming on 18 June 1967. Law stated that shortly after the film's production ended, shooting began on Barbarella. This led to the same sets, such as the set for Valmont's teen discotheque, being used in both films.

Although De Laurentiis set aside 781.25 million lire with which to make the film, the final budget came to only 200 million. Despite their difficult working relationship, De Laurentiis was highly impressed by Bava's efforts, especially by the visual effects, jokingly declaring that he would inform Paramount that the film had gone overbudget, and that a matte painting of the car hangar in Diabolik's lair was actually a set that cost $200,000. He decided that the money saved from the production needed to be used immediately to make a sequel, but Bava refused, later telling Cozzi, "I informed [De Laurentiis] that Diabolik was immobilized, that he was suffering from a permanent disability—that he was dead!". The director would work again for De Laurentiis only twice more: on two episodes of the television miniseries The Odyssey, which he co-directed with Franco Rossi, and on Sergei Bondarchuk's Waterloo, for which he went uncredited for his visual effects work. His recollection of his experiences on Danger: Diabolik led Bava to turn down De Laurentiis' offer to provide special effects for King Kong, recommending Rambaldi instead. Danger: Diabolik would also prove to be the only film Bava would direct for a major Hollywood studio such as Paramount; for the remainder of his career, he would work for independent producers who Lamberto Bava often described as "dodgy".

Lucas has analyzed Bava's extensive use of visual effects photography in Danger: Diabolik and its implementation of techniques used in his earlier films, albeit to a more flamboyant degree as allowed by the film's budget. With regard to the film's first sequence, shot in an alleyway near Dinocittà, he states that Bava opens the film with "a parade of illusions", most notably the establishing shot of a bank, which utilizes a travelling matte that adds multiple floors to a single-floor structure while duplicating the structure to the opposite side of the screen; to visually lend scale to the matte, toy figurines are used to represent soldiers standing guard on both sides of the structure, while a toy tank is visible in the foreground as a motorcade of police officers on motorcycles ride through the structure's gate in the lower section of the composition—the only part of the set that was actually built. He describes this as "a staggering pre-digital effect, and it's only there not to be noticed".

Music

Morricone's score for Danger: Diabolik, which was conducted by Bruno Nicolai, was the composer's only collaboration with Bava, and was influenced by his work with the avant-garde/free improvisation collective Gruppo di Improvvisazione Nuova Consonanza. It includes a title song, "Deep Down", featuring vocals by singer and actress Maria Cristina "Christy" Brancucci—whose other collaborations with Morricone include "Run, Man, Run" in The Big Gundown and "Man for Me" in O.K. Connery—which appears throughout the film in a variety of arrangements. It is primarily used to communicate Eva's love for Diabolik, which is furthered by Alessandro Alessandroni's playing of a sitar during the bridge. A "chase theme" frequently used in action scenes prominently features a double-tracked electric guitar motif, also performed by Alessandroni, that bears similarity to that featured in Neal Hefti's "Batman Theme". Among the film's most experimental cues include the psychedelic discotheque theme, which utilizes "wall of sound" reverb to enhance (at alternating points) a vocal chorus and a brass section providing the melody over a rhythm section consisting of a fuzz guitar and drum kit, and the identikit theme, which includes an improvised performance on an atonal keyboard by Nicolai. Lucas deems the highlight of the score to be the cue featured when Diabolik and Eva recover the gold, beginning with a solo melisma performed by Edda Dell'Orso, which is replaced by a vocal chorus performed by Alessandroni's I Cantori Moderni choir and later by a rock band accompaniment that "feels closely allied to Morricone's Spaghetti Western work while also feeling perfectly at home in an espionage milieu".

Although an Italian-language version of "Deep Down" was released by Parade as a 45 RPM single, the original score has never seen a full, authorized release, as the original master tapes were destroyed in the 1970s by a warehouse fire. This has resulted in several unauthorized reconstructions of the score being released on CD, the most widely distributed of which is a version attributed to Pallottola Foro, which also includes dialogue extracts from the film. In the March 2002 issue of GQ's list of the "Top 10 Movie Soundtracks of All Time", Morricone's score was ranked third.

Release

Danger: Diabolik's release was highly anticipated in Italy, and this led to De Laurentiis threatening to sue producers of films whose titles were similar to his, such as Superargo Versus Diabolicus and Arriva Dorellik. Danger: Diabolik was submitted to the Italian Board of Censors in December 1967 and, after five brief cuts were made to the film, it was released in Italy on 24 January 1968. The film was described by film historian Roberto Curti as a "financial disappointment for De Laurentiis". It grossed 265 million Italian lire between January and July 1968 with a total of 715 million lire by the end of its theatrical run. It opened in Paris in April 1968 under the title Danger Diabolik.

In the United States, Danger: Diabolik was first released in August 1968, and opened in New York in December that year. The film played in major cinemas during its first run, initially on a double bill with 5 Card Stud, followed by later showings that paired it with either its sister production Barbarella or other Paramount films, including Rosemary's Baby, Riot and Waterhole #3; although primarily considered to be a supporting feature by Paramount, in some areas of the country it was promoted to A-movie status due to positive word of mouth. As bookings decreased, it was relegated to supporting exploitation films at grindhouses and drive-ins, such as The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies and Blood Rites, before falling into obscurity. In the United Kingdom, Danger: Diabolik's release was delayed until 19 January 1969 and was shown in a version that was reportedly cut by 17 minutes compared to the original prints. Paramount's English-language trailers for the film were narrated by Telly Savalas, who would later star in Bava's Lisa and the Devil.

Home media and television

Two English-language dubs of Danger: Diabolik were produced, both featuring the voices of Law, Mell and Terry-Thomas. The original English version, used for the film's theatrical, DVD and Blu-ray releases, presented the remaining cast dubbed with predominantly British accents, and included the voices of Dan Sturkie and Bernard Grant as Ginko and Valmont respectively. The second version, used for the film's VHS and LaserDisc releases, was created when the original sound elements for the dubbed version (aside from those of the three aforementioned performers) were believed to be lost; the non-English-speaking actors were dubbed with predominantly American accents, and Richard Johnson is reported to be among the voice actors for this version. This version also greatly remixed the audio levels for the sound effects and music, and dropped the Danger: from the original English version's title due to using an Italian print. Lucas considers the vocal performances of the second version to be inferior to the original, particularly deeming the performances of Piccoli, Celi, Lucia Modugno and Annie Gorassini to be negatively impacted by their newer dubbers.

Footage from the film was extensively featured in the music video for the Fatboy Slim remix of "Body Movin' " by the American hip-hop group Beastie Boys. This footage is interspersed with new material, created using many of the same techniques as Bava's film, depicting Diabolik (portrayed by Ad-Rock) humorously attempting to steal a fondue recipe from a villain (Adam Yauch) and his butler (Mike D). Yauch, who also directed the video under his alias "Nathanial Hörnblowér", described the film as "campy in a way, but not in a bad way" and found the acting and direction to be "ridiculous" but with the set design being "so over the top the acting is appropriate"; he believed that the film's appeal lay in its depiction of Diabolik as a criminal, in contrast to the superheroes of most comic book film adaptations.

The second English version was featured on the Sci-Fi Channel incarnation of Mystery Science Theater 3000 (MST3K), a series which provides mocking commentary over B-movies interspersed with sketches, which aired on 8 August 1999 as the thirteenth and final episode of the show's tenth season and (up until 2017) the final episode of the series overall. Lucas has criticized the show's selection and handling of the film, stating "The fact that such an accomplished film would be singled out for insult and lampoon on the program showed that it was running out of appropriate fodder."

Reception

Contemporary

Upon its initial release, Howard Thompson of The New York Times called Danger: Diabolik "infantile junk". Variety was also negative, calling it a "dull Dino De Laurentiis programmer" whose "[b]izarre sets, poor process work, static writing and limp direction spell pure formula fare for lowercase grind bookings." A more favorable review came from Roger Ebert of the Chicago Sun-Times, who gave it a two-and-a-half star rating out of four, stating that although he felt that the film was "long and eventually loses track of itself", he deemed it to be "very nearly the movie Barbarella should have been" due to "look[ing] better put-together (although its budget must have been smaller)", noting Bava's "thorough grounding in schlock exploitation films" and praising his use of clichés. He also found Piccoli's casting as Ginko to be "nothing short of hilarious". In Britain, a review came from David Hutchison for the April 1969 issue of Films and Filming, who deemed the film's use of spy-fi tropes to be outdated, but made a point that "the comic strip has a great many affinities with the motion picture; both are a series of separate pictures and take the same advantage of light, shade, colour and perspective. Bava is obviously well aware of this and the result is a film strip cartoon which, despite its faults, is generally more successful than either Modesty Blaise or Barbarella in capturing an elusive comic strip flavour".

Betty Marcus of Fort Lauderdale News was enthusiastic, describing the film as "pure entertainment", noting that "it brings back the excitement and gimmickry of the Bond films and the high-camp corn of the Batman television series" and finding the visual effects to be "magnificent". In Australia, a review in the 6 September 1968 edition of The Age called the film "a real surprise, splendid stuff"; aside from noting the influence of Fantômas and Raffles, it defined the film in the context of Bava's filmography as cinematographer and director, stating that "Danger: Diabolik demonstrates [Bava's] graphic eye for an image, his fluid camera style and arresting way with colour composition", and that "Although pictures by Bava have been pouring out of Italy for years, I can recall only one or two here - no horror of course, because this genre, which allows him greater scope, is still banned in Australia". The Monthly Film Bulletin also gave the film a positive review, noting that: "Bava's superb visual sense stands him in good stead in this comic-strip adventure which looks like a brilliant pastiche of the best of everything in anything from James Bond to Matt Helm." In his 1970 reference book Science Fiction in the Cinema, John Baxter declared that "Judex is alive and living at Cinecittà", praising Bava as a "brilliant cinematographer and one of Italy's finest fantasy film-makers" who gives the film "the visual pace of a streamlined juggernaut", and applauded Law's "dazzling characterization".

Retrospective

Danger: Diabolik's status as a cult film gradually grew as studies of Bava's career began, and was explored in the DVD featurette From Fumetti to Film, which drew attention to the film's relation to its comic book roots. According to Lucas, the film was generally well received by contemporary critics and audiences who viewed it in the context of its pop art aesthetic, but it was disregarded as "not only artificial, but frivolous" by the counterculture of the time due to their preference for the realism in New Hollywood films such as Midnight Cowboy, The Wild Bunch and Woodstock. He states that its popular reception evolved from being seen as "quaintly campy" in the 1970s, "interesting" in the 1980s, to "fashionable" in the 1990s due to its VHS and LaserDisc release—the result of a successful letter-writing campaign among fans directed at a hesitant Paramount Home Video—coinciding with new trends in lounge music, style and fashion.

In a 2012 issue of Film International, John Berra similarly noted that the film had initially "been left to languish in obscurity since its staggered international release at the end of the 1960s" and that it "mostly existed as a kitsch reference point or as an easy target for tongue-in-cheek parody", citing both its MST3K episode and the "Body Movin'" music video as examples. Berra described the film as being "warmly received" by the internet community, who routinely embraces comic book adaptations and seeks to adopt films that have been neglected by popular audiences. Lucas identifies the "uncomplicated magnetism" of Law and Mell's onscreen sexual chemistry as one of the primary factors of the film's cult following. Similarly, Kat Ellinger believes that both Danger: Diabolik and Barbarella reflect trends of the sexual revolution, presenting a morally ambiguous worldview that stands in contrast to most 21st century comic book film adaptations such as the Marvel Cinematic Universe, which she described as largely "masculine and asexual". This is seen not only in its characterization of Diabolik and Eva, especially the similarity of the latter's role to the assertive female characters frequently seen in Bava's other films, but also in the film's production and costume design. She particularly notes a circular motif in Mogherini's art direction, such as the dial on Diabolik's safe (which bares some resemblance to a woman's breast), Diabolik and Eva's bed—"a giant circular statement that invites an orgy of at least ten"—and their swimming pool.

Video Librarian noted that the film was "guaranteed to delight viewers whose tastes run to the outré", praising Morricone's score, Law and Mell's acting, and noting that the "real star is Bava" stating that "the film is colorful almost to the point of garishness". Cinefantastique also discussed the film's visuals, noting that: "[Bava's] color rich, brilliantly artificial-looking compositions were the cinematic equivalent of comic book art even before he tackled the form." The magazine also found that the special effects rivalled those of Bond series veteran Ken Adam. The review also praised Law's work in the film noting his "amazingly expressive eyebrows" and declared the film as "1960s pop-culture heaven." Ignatiy Vishnevetsky of The A.V. Club compared the film to Barbarella, opining that Diabolik had "a sense of infectious, amoral fun" which Barbarella lacks. He declared the film to be among "the definitive touchstones of Euro pulp." Empire included the film on its list of the top 500 greatest films. They described the movie as "thin as a poster, but still amazing cinema—a succession of striking, kinetic, sexy, absurd images accompanied by a one-of-a-kind Ennio Morricone score that revels in its casual anarchy."

Legacy and influence

Danger: Diabolik and Barbarella were part of a minor trend of film adaptations of European comics that emphasized mild sadomasochism and late 1960s fetish gear; aside from these two films, 1968 saw the release of Piero Vivarelli's similarly themed Satanik. These were followed by Bruno Corbucci's Ms. Stiletto (1969) and Corrado Farina's Baba Yaga (1973). The production and costume design of both films also reflected a larger movement of retrofuturism seen in European genre films of the 1960s and 1970s. These include Pasquale Festa Campanile's The Libertine and Check to the Queen (both of which were designed by Mogherini), Umberto Lenzi's So Sweet... So Perverse, Tinto Brass' Col cuore in gola, Fulci's One on Top of the Other and A Lizard in a Woman's Skin, Elio Petri's The 10th Victim, Piero Schivazappa's The Laughing Woman and Radley Metzger's Camille 2000 and The Lickerish Quartet. The look of Diabolik in the film influenced his depiction in the fumetti: because the film's audiences could see Diabolik's mouth due to Law's mask being made out of latex, the series' artists, Enzo Facciolo and Sergio Zaniboni, gave up on trying to shade in his mouth, and simply outlined it.

Along with Barbarella, Danger: Diabolik is one of several genre films that is referenced in Roman Coppola's film CQ, which explicitly pays tribute to several scenes in the film, such as Eva's showering and her lovemaking with Diabolik on top of money; Law also appears in the film in a supporting role. British director Edgar Wright similarly cited it as an influence on his film Scott Pilgrim vs. the World, describing Danger: Diabolik as an "Italian influence, a sense of completely unbridled imagination. They don't make any attempt to make it look realistic. Mario Bava's composition and staging has a real try-anything attitude."

Further films, TV series and radio dramas

In 1991, Rai 2 announced a live-action TV series based on Diabolik, which was to be produced by M Films Produzione and directed by Rospo Pallenberg. Although a 100-minute pilot episode was planned, the series did not come to pass. In autumn 1999, the French television network M6 began airing a 40-episode animated series, Saban's Diabolik, an American-French-Italian-Japanese co-production between Saban Entertainment, M6, Mediaset, Toho and Ashi Productions. The series was influenced by the critical and commercial success of Batman: The Animated Series, and reworked its characters for a younger audience. It follows Diabolik and Eva as they commit heists to expose the atrocities of Diabolik's adoptive brother Dane, who has taken over their father's organization The Brotherhood, all while avoiding being captured by Ginko. The English dub of the series was initially set to air on Fox Family Channel in the United States in 2000, but was cancelled before being aired, although the series was broadcast in Australia.

In 2000, Radio Monte Carlo produced a radio drama adaptation of several of the original fumetti stories from Diabolik. The series was broadcast on Rai Radio 2, and aired for 20 episodes on weekdays from 13 November to 8 December. Adapted by Armando Traverso, directed by Arturo Villone and featuring original music by Giovanni Lodigiani, the series featured the voices of Luca Ward as Diabolik, Roberta Greganti as Eva and Luca Biagini as Ginko.

In the early 2000s, a new film based on Diabolik, directed by Christophe Gans and starring Mark Dacascos and Monica Bellucci, was in development. Gans opined that "The Bava film is unique and I'd never, ever want to copy it. But let's see where we can take Diabolik today for a totally new and different Pop art experience." The film did not go into production. In 2002, screenwriter and Diabolik historian Mario Gomboli announced that a French production of Diabolik was to be made with a contemporary setting from a script written by Carlo Lucarelli and Giampiero Rigosi. The script was completed in April 2007, with filming set to begin in January 2008, but the production stalled. In 2012, Sky Group, in conjunction with Sky France and Sky Italia, produced a teaser trailer for a second proposed live-action TV series based on Diabolik, but the series did not enter production.

In December 2018, Rai Cinema president Paolo del Brocco announced that a new adaptation of Diabolik was in development, with the Manetti Bros. directing and co-writing the screenplay with Michelangelo La Neve and Gomboli. The cast includes Luca Marinelli as Diabolik, Miriam Leone as Eva, Valerio Mastandrea as Ginko, in addition to Serena Rossi, Alessandro Roja and Claudia Gerini. The film was originally set to be released in Italy by 01 Distribution on 31 December 2020, but was then pushed back to 16 December 2021, due to the second wave of the COVID-19 pandemic in Italy. In April 2021, two sequels to the film were announced, which are scheduled to begin back-to-back production in October.
