Brad Pitt, Leonardo DiCaprio, Margot Robbie praise Quentin Tarantino

Brad Pitt, Leonardo DiCaprio and Margot Robbie brought glamour to London for the premiere of 'Once Upon a Time in Hollywood' on Tuesday. The film directed by Quentin Tarantino arrives in Europe after it opened in North America raking in 40 million dollars, a career best for Tarantino.

Set in the late 1960s against the backdrop of the Manson family murders, the film sees DiCaprio's character as a struggling actor who goes to Italy for more work in the genre that would become known as a 'Spaghetti Western'. Italian director Sergio Leone was famed for that genre and made the films 'Once Upon a Time in the West' (1968) and 'Once Upon a Time in America' (1984). The film is set to hit UK cinemas on August 14.
