The actors are starring in Once Upon a Time In Hollywood, Tarantino’s ninth film about actress Sharon Tate‘s murder at the hands of Charles Manson’s followers.

In a previous release, Tarantino called the film 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.”

This is the second time Pitt and DiCaprio have worked with Tarantino, with the former starring in 2009’s Inglorious Bastards as the Nazi-killing American Lt. Aldo Raine, and the latter starring as the villainous, slave-owning Calvin Candie in 2012’s Django Unchained. Both films gorily reimagined history, as Once Upon a Time in Hollywood will likely do.

While the film revolves around Tate’s murder, which took place on Aug. 9, 1969, when the actress was more than eight months pregnant with her child with director Roman Polanski, the story is reportedly not a full chronicle of the Manson family murder spree. (Manson died in prison last year at the age of 83).

Once Upon a Time in Hollywood is expected to hit theaters Aug. 9, 2019, which marks the 50th anniversary of Tate’s death.
