Watch: Pitt & DiCaprio Star in Trailer for Tarantino's New Film 'Once Upon a Time in Hollywood'

The new trailer for Quentin Tarantino's new film "Once Upon a Time in Hollywood" is here.

There's not much known about the film – the ninth effort from the director – but it's loaded with star power. Brad Pitt and Leonard DiCaprio take the lead roles. Pitt plays Cliff Booth, a stunt double for DiCaprio's Rick Dalton, an actor best known for a Western TV series who is also Cliff's best friend. Dalton is trying to transition into movies but it's not going so well, only picking up guest roles. He's also thinking about moving to Italy – oh and his neighbor is actress Sharon Tate (played by Margot Robbie), who was infamously murdered in her home by Charles Manson's followers while she was pregnant with filmmaker Roman Polanski's child.

A description for "Once Upon a Time..." says the film is set in 1969 Los Angeles when Cliff and Rick "embark on an odyssey to make a name for themselves in the film industry." The movie also stars Al Pacino, Dakota Fanning, Damian Lewis, Bruce Dern, Emile Hirsch, Lena Dunham, Rumer Willis, and many more.

"Once Upon a Time..." hits theaters on July 26. Check out the trailer below.
