The stars are finally aligning for Quentin Tarantino’s next movie. Sony has announced that the L.A.-centric story, titled Once Upon a Time in Hollywood, will bring together two of Tarantino’s most distinguished alums: Brad Pitt (who previously starred in Inglourious Basterds) and Leonardo DiCaprio (who made a villainous turn in Django Unchained). Plot details for the mysterious film, which was at one point rumored to be a biopic of sorts about Charles Manson’s cult, are also finally being revealed.

According to Tarantino himself, the story “takes place in Los Angeles in 1969, at the height of hippy Hollywood. The two lead characters are Rick Dalton (Leonardo DiCaprio), former star of a western TV series, and his longtime stunt double, Cliff Booth (Brad 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.”

Rumors have abounded for several months that Margot Robbie is in talks to play Tate, but nothing has been confirmed. Alas, it would seem that Tarantino’s finished story is also drawing the plot away from Manson and his followers, despite previous reports; the movie sounds like it will focus less on the murders themselves and more on the wider tableau of Hollywood in that peculiar era. Perhaps the Manson Family will simply be the specters in the distance, lending the film a malevolent edge? Will an actor even be cast to play Manson? After all, the cult leader wasn’t present the night of the Tate murders—so Tarantino could get away with that.

Then again, the characters Rick and Cliff sound like performers who easily could have gotten tangled up in Manson’s corner of California. The mastermind and his murderous followers spent a large chunk of time living on Spahn Ranch, a former movie set that had regularly been used for westerns in its heyday. The character of Cliff might have also been inspired by Donald Shea, a real Hollywood stuntman who was murdered by Manson followers shortly after the Tate murders.

“I’ve been working on this script for five years, as well as living in Los Angeles County most of my life, including in 1969, when I was seven years old,” Tarantino said in a statement. “I’m very excited to tell this story of an L.A. and a Hollywood that don’t exist anymore. And I couldn’t be happier about the dynamic teaming of DiCaprio & Pitt as Rick & Cliff.”

Once Upon a Time in Hollywood, Tarantino’s ninth film, will hit theaters on August 9, 2019, the 50th anniversary of the Tate killings.
