Between the story of Leonardo DiCaprio’s depressed/fading actor Rick “Fuckin” Dalton trying to maintain his career alongside his best friend Cliff Booth, played by Brad Pitt, and its crossover into the real-life antics of Charles Manson and his murderous “family”, there is certainly no room for chaste examination in this love letter to a golden era of excess and freedom.
If Quentin Tarantino wanted to start trying for a PG-13 rated project Once Upon A Time In Hollywood would have been the worst film to attempt such a result, especially after reading those specific descriptors on Box Office Mojo.
