The Manson Family were a cult who lived in a commune on a California ranch, and committed a series of murders in the summer of 1969 at the command of their leader, Charles Manson - an ex-convict and aspiring musician. Tate was married to director Roman Polanski and was eight-and-a-half months pregnant at the time of her death.

Leonardo DiCaprio and Brad Pitt will portray best friends - one is a former TV star, the other is his longtime stunt double. His sidekick Cliff Booth (Pitt) - who's also his stunt double - is looking for the same thing.
This is Tarantino's ninth feature. Set against the backdrop of the Manson murders, the ensuing saga, described by Sony as "a story that takes place in Los Angeles in 1969, at the height of hippy Hollywood", will be a fractured, multi-storyline affair reminiscent of Pulp Fiction, although details are so far relatively scarce.
Back in June, Leonardo DiCaprio - who also starred alongside Robbie in The Wolf of Wall Street - gave fans a first look at the upcoming Quentin Taratino flick by sharing a photo of him and Brad Pitt - the film's other star - decked out in '60s garb. However, Variety reported in mid-July the release date has been changed to July 26, 2019.
However, Sharon Tate's sister Debra has said she is "very happy" that the release date is being shifted away from the anniversary of her sibling's murder, according to the New York Daily News.
