Brad Pitt and Leonardo DiCaprio also star in the movie, which is slated for a 2019 release.

Tarantino previously described the film's synopsis in a press release: It's “a story that takes place in Los Angeles in 1969, at the height of hippy Hollywood. The two lead characters are Rick Dalton (DiCaprio), former star of a western TV series, and his longtime stunt double Cliff Booth (Pitt). Both are struggling to make it in a Hollywood they don’t recognize anymore. But Rick has a very famous next-door neighbor... Sharon Tate.”

Robbie shared her glee about working with Tarantino with USA TODAY in May.

"It’s always been a bucket list thing for me to work on a Tarantino film," she said, "so I’m obviously ridiculously excited and grateful."
