2019–present: Established actress and producer
Robbie's first release of 2019 was the LuckyChap Entertainment production Dreamland, a poorly received period crime thriller set during the 1930s Dust Bowl. She began executive producing the comedy series Dollface, which streamed on Hulu from 2019 to 2022. Robbie was filmmaker Quentin Tarantino's only choice to portray the late actress Sharon Tate in his period film Once Upon a Time in Hollywood, starring Leonardo DiCaprio and Brad Pitt. With the Tate–LaBianca murders serving as a backdrop, the film tells the story of a fading character actor (DiCaprio) and his stunt double (Pitt) as they navigate New Hollywood in 1969 Los Angeles. Feeling "an enormous sense of responsibility", Robbie prepared for the role by meeting Tate's family members and friends, watching all of her films and reading the autobiography by Tate's then-husband, Roman Polanski. Once Upon a Time in Hollywood premiered at the 2019 Cannes Film Festival to critical acclaim, and was a commercial success with a worldwide gross of $374.3 million. Despite many bemoaning Robbie's lack of lines in the film, Robbie Collin of The Daily Telegraph highlighted a scene with Robbie in the cinema, which he found to be the film's "most delightful" scene.
Also in 2019, she starred as Kayla Pospisil, a composite character based on several Fox News employees, in Jay Roach's drama Bombshell. Co-starring Charlize Theron and Nicole Kidman, the film recounts stories of various female personnel at the news network and their sexual harassment by the network's chairman Roger Ailes. Robbie based her character's accent on Katherine Harris. The film received positive reviews; Kenneth Turan of the Los Angeles Times wrote, "Robbie [is] at her best, the arc of her story is so crushing that it stays with you the longest." For her performances in Once Upon a Time in Hollywood and Bombshell, she received two nominations for the BAFTA Award for Best Actress in a Supporting Role, and for the latter she received nominations for an Academy Award, a Golden Globe and a Screen Actors Guild Award; all in the Best Supporting Actress category.
Robbie began the new decade by reprising the role of Harley Quinn in Cathy Yan's Birds of Prey (2020). Determined to make a female ensemble action film, she pitched the idea for the film to Warner Bros. in 2015. Robbie spent the subsequent three years developing the project under her production company, making a concerted effort to hire a female director and screenwriter. Birds of Prey, along with Robbie's performance, gained generally positive reviews; Ian Freer of Empire wrote that "the MVP is Robbie, who lends Harley charming quirk and believable menace, hinting at Harley's inner life without reams of dialogue." She received two nominations at the 46th People's Choice Awards.
Robbie served as a producer on Promising Young Woman (2020), a comedy thriller by writer-director Emerald Fennell, starring Carey Mulligan as a woman who seeks to avenge the rape and death of her best friend. The film received acclaim, earning a nomination for the Academy Award for Best Picture. In 2021, Robbie reprised her voice role as Flopsy Rabbit in Peter Rabbit 2: The Runaway, which received mixed reviews and grossed $153.8 million worldwide. She also made her third outing as Quinn in the standalone sequel The Suicide Squad, written and directed by James Gunn. Due to the COVID-19 pandemic, the film was simultaneously released theatrically and on the streaming service HBO Max. Owen Gleiberman praised Robbie's "delectable performance" in it. She also served as an executive producer for the Netflix miniseries Maid.
In 2022, Robbie reprised her role as Donna Freedman for the final episode of Neighbours. She starred alongside an ensemble cast in David O. Russell's period comedy Amsterdam, based on the 1933 Business Plot. The film emerged as a critical and commercial failure. In her second film release of the year, she played Nellie LaRoy, an actress inspired by silent movie star Clara Bow, in Damien Chazelle's comedy-drama Babylon. In preparation, she studied the works of Bow and researched her traumatic childhood. She described LaRoy as "the most physically and emotionally draining character I've ever played". The film polarised critics and had poor box office returns, though her performance received praise; Caryn James of BBC Culture opined, "Robbie's bold, charismatic performance makes Nellie a daring, endlessly spiraling, sympathetic figure". She received another Golden Globe nomination for Best Actress, although the underperformance of her two major releases that year led some commentators to brand her as "box office poison" at the time.
In the following year, Robbie had a single scene in Wes Anderson's ensemble comedy film Asteroid City. Chris Hewitt of the Star Tribune described her "impassioned acting in her lone scene" as "perfectly judged". The fantasy comedy Barbie, co-starring Ryan Gosling as Ken, was her next film release. As producer, Robbie secured the rights from Mattel for a film about the eponymous fashion doll in 2018. She hired Greta Gerwig to write and direct the film, and took on the title role herself after Gal Gadot declined her offer. In preparation, Gerwig and Robbie watched old Technicolor musicals such as The Red Shoes (1948) and The Umbrellas of Cherbourg (1964). Variety reported that Robbie earned $12.5 million for the role, the highest for an actress in Hollywood that year. Vulture's Alison Willmore took note of how much Robbie fit the part, and commended her for combining both "heartbreaking earnestness" and "humor" in her performance. With a worldwide gross of over $1.4 billion, Barbie emerged as Robbie's highest-grossing release. She received further BAFTA and Golden Globe nominations for her performance, in addition to a nomination for the Academy Award for Best Picture.
Also in 2023, Robbie produced Fennell's second directorial, Saltburn. The 2024 Sundance Film Festival marked the release of her next production, Megan Park's comedy film My Old Ass. Robbie starred alongside Colin Farrell in Kogonada's 2025 film A Big Bold Beautiful Journey Robbie starred as Catherine Earnshaw alongside Jacob Elordi as Heathcliff in Wuthering Heights, the romantic drama film written and directed by Emerald Fennell and loosely based on the Emily Brontë novel. The film was released theatrically on February 13, 2026.
