In reality, the Manson murders led to the brutal deaths of five people, including actress Sharon Tate, in 1969. Though Charles Manson wasn’t present at the crime scenes, he played a pivotal role in orchestrating the deaths. While the events of that night are no less brutal in Once Upon a Time in Hollywood, Quentin Tarantino ultimately gives new meaning to the Manson family murders. Though the film has been called out for some significant (and controversial) historical inaccuracies, it’s been lauded as a love letter to the movie-making industry he loves. And in one way or another, it’s helped a new generation, like Laura Dern’s kids, learn about one of Hollywood’s darkest moments.
