Once Upon a Time… in Hollywood is one of the most highly-anticipated film releases of 2019, starring Margot Robbie, Leonardo DiCaprio and Brad Pitt. Lena Dunham makes an appearance, too.

But the film is not without its contentious issues.

Set in 1969 Los Angeles, the Charles Manson murders are the backdrop to a story about an aging actor (DiCaprio) and his stunt double (Pitt). Sharon Tate (Robbie) is their Hollywood neighbour, and one of the seven victims of the Manson killings. Although the newest trailer shows that the murders aren’t the primary focus of the film, using the real-life deaths of innocent people for what looks to be a very cool and glamorous film has been a controversial move for some critics.

Another issue is that DiCaprio’s character idolises director Roman Polanski. This is particularly uncomfortable because a recording of Tarantino defending Polanski’s 1977 rape charge surfaced in 2003, saying: “It was statutory rape… he had sex with a minor. That’s not rape.”

The director has also faced backlash over not giving Robbie enough lines in his newest film.

Quentin Tarantino has added more Margot Robbie scenes to Once Upon a Time… in Hollywood
