The upcoming film is set in the year 1969 and primarily will follow the story of TV star Rick Dalton (Leonardo DiCaprio) and his best friend/stuntman Cliff Booth (Brad Pitt). While they used to be big, their stars are fading, and Hollywood is slowly beginning to look unrecognizable to them. Their fortunes seem to turn when they discover that Sharon Tate is their new neighbor... but anyone familiar with real world events knows that there isn't much of a happy ending there. That being said, it's unclear exactly how the film will treat the actual events - and Quentin Tarantino has been known to alter history (in case you didn't know, Adolf Hitler didn't die in a burning movie theater being shot in the face hundreds of times by a furious American soldier, as portrayed in Inglorious Basterds).
