The Tarantino pic has been referred to as a Pulp Fiction-like tapestry of stories set in L.A. in the summer of 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: Tate (Robbie).

David Heyman, Tarantino and Shannon McIntosh are producing, and the studio has set it for an August 9, 2019 release worldwide.
