Everything we know about Quentin Tarantino's new movie, which stars Brad Pitt and Leonardo DiCaprio and involves the Manson Family murders

Brad Pitt and Leonardo DiCaprio are teaming up with Quentin Tarantino for the director's upcoming ninth film, "Once Upon a Time in Hollywood," Tarantino announced on Wednesday.

Pitt and DiCaprio were in talks to star in the film for weeks, but the contract negotiations for it were reportedly so "strenuous" that DiCaprio was ready to walk away from the project in January, sources told The Hollywood Reporter.

Pitt previously worked with Tarantino on 2009's "Inglorious Basterds," and DiCaprio appeared in 2013's "Django Unchained."

"Once Upon a Time in Hollywood" is set for release on August 9, 2019.
