Creative credit
A clause in Spielberg's contract with Universal Studios prevented him from directing another film while preparing E.T. the Extra-Terrestrial. According to Tobe Hooper, the core concept of the film was an idea he pitched to Spielberg after turning down the offer to direct Night Skies. Writer Michael Grais stated that "we weren't really 'working' with Spielberg because he was on E.T.", and that Spielberg only had sporadic meetings with the writers in MGM's commissary. E.T. and Poltergeist were released a week apart in June, 1982; Time and Newsweek referred to it as "The Spielberg Summer". There were suggestions that Spielberg, in addition to being Poltergeist's co-producer and co-writer, had also served as its de facto co-director. This view was bolstered by various statements Spielberg made about his involvement, including a Los Angeles Times quote on May 24, 1982: "Tobe isn't ... a take-charge sort of guy. If a question was asked and an answer wasn't immediately forthcoming, I'd jump in and say what we could do. Tobe would nod agreement, and that became the process of collaboration."
That same article noted that the Directors Guild of America had opened an investigation into the "question of whether or not Hooper's official credit was being denigrated by statements Spielberg has made, apparently claiming authorship." The investigation ended in an arbitrator's ruling that MGM/UA Entertainment Co. must pay $15,000 to Hooper because the studio gave producer Spielberg a bigger credit than Hooper got in its trailers, although also noting that "broader issues of dispute exist between producer-writer (Spielberg) and the director" (damages of $200,000 were originally sought by the DGA). Co-producer Frank Marshall told the Los Angeles Times that "the creative force of the movie was Steven. Tobe was the director and was on the set every day. But Steven did the design for every storyboard, and he was on the set every day except for three days when he was in Hawaii with Lucas." However, Hooper stated that he "did fully half of the storyboards."
The week of the film's release, The Hollywood Reporter printed an open letter from Spielberg to Hooper:
Regrettably, some of the press has misunderstood the rather unique, creative relationship which you and I shared throughout the making of Poltergeist.
I enjoyed your openness in allowing me, as a writer and a producer, a wide berth for creative involvement, just as I know you were happy with the freedom you had to direct Poltergeist so wonderfully.
Through the screenplay you accepted a vision of this very intense movie from the start, and as the director, you delivered the goods. You performed responsibly and professionally throughout, and I wish you great success on your next project.
In a 2007 Ain't It Cool News interview, Zelda Rubinstein discussed her recollections of the shooting process. She said "Steven directed all six days" she was on set: "Tobe set up the shots and Steven made the adjustments." She also alleged that Hooper "allowed some unacceptable chemical agents into his work," and that during her audition, "Tobe was only partially there." Comments from actor James Karen, concerning a 25th-anniversary Q&A event which both attended, categorized Rubinstein's remarks as unfair to Hooper. "She laid into Tobe and I don't know why ... Tobe was kind to her."
In a 2012 Rue Morgue article commemorating Poltergeist's 30th anniversary, interviews were conducted with several cast and crew members. In response to the magazine's query about the authorship issue, cast members unanimously sided with Hooper. James Karen said, "Tobe had a hard time on that film. It's tough when a producer is on set every day and there's always been a lot of talk about that. I considered Tobe my director. That's my stand on all those rumours." Martin Casella stated: "So much of Poltergeist looks and feels like a Spielberg movie but my recollection is that Tobe was mostly directing." Oliver Robins: "The guy who sets up the shots, blocks the actors and works with the crew to create a vision is the director. In those terms, Tobe was the director. He's the one who directed me, anyway." Make-up and effects artist Craig Reardon said Spielberg often had the final say. The original version of the cancerous steak, for instance, was created by Reardon per Hooper's specifications—but vetoed by Spielberg: "Although the first steak did not represent a killing amount of work, it had consumed enough time and effort—none of which I could afford to waste—that I determined in the future to make certain whatever I prepped would be approved in advance by Spielberg as well as Hooper."
Hooper was asked about the controversy in a 2015 interview with online journal Film Talk and said the rumors originated from a Los Angeles Times article that reported on Spielberg shooting footage of "little race cars" in front of the house, while Hooper was busy elsewhere shooting another scene. "From there it became its own legend. That is how I remember it; I was making the movie and later on, I heard this stuff after it was finished. I really can't set the record much straighter than that."
According to the Blumhouse Productions website, first assistant cameraman John R. Leonetti reported that Spielberg directed the film more so than Hooper, stating, "Hooper was so nice and just happy to be there. He creatively had input. Steven developed the movie, and it was his to direct, except there was anticipation of a director's strike, so he was 'the producer' but really, he directed it in case there was going to be a strike and Tobe was cool with that. It wasn't anything against Tobe. Every once in a while, he would actually leave the set and let Tobe do a few things just because. But really, Steven directed it."
Following Hooper's death in 2017, director Mick Garris, a publicist on the film who made several on-set visits, came to Hooper's defense on the Post Mortem podcast:
Tobe was always calling action and cut. Tobe had been deeply involved in all of the pre-production and everything. But Steven is a guy who will come in and call the shots. And so, you're on your first studio film, hired by Steven Spielberg, who is enthusiastically involved in this movie. Are you gonna say, 'Stop that... let me do this'? Which [Tobe] did.
[...] Tobe was a terrific filmmaker. I don't think it's that Steven was controlling. I think it was Steven was enthusiastic. And nobody was there to protect Tobe. But all of the pre-production was done by Tobe. Tobe was there throughout. Tobe's vision is very much realized there. And Tobe got credit because he deserved credit. Including... Steven Spielberg said that.
[...] Yes, Steven Spielberg was very much involved. It's a Tobe Hooper film.
