Quentin Tarantino’s ninth film, Once Upon a Time in … Hollywood, covers a lot of territory in three acts, all set in the Los Angeles of 1969 just as Charles Manson was working his sicko spell on a group of slavish followers. Once Upon a Time is the story of fading TV star Rick Dalton (Leonardo DiCaprio) and his longtime stunt double Cliff Booth (Brad Pitt), two guys facing the end of their era with a martini-shaker jumble of anxiety and grace.
