Brad Pitt JOKES About Why He Had Never Worked with Leonardo DiCaprio

"Extra's" Renee Bargh was with Brad Pitt as the star shut down Hollywood Blvd. for the premiere of "Once Upon a Time in Hollywood."

The film, set in 1969, recreates Old Hollywood, and centers on a western actor, played by Leonardo DiCaprio, and his stunt double and longtime friend, played by Pitt, who want to make a name for themselves in the film industry.

It was Quentin Tarantino who finally brought Pitt and DiCaprio together for a movie. Brad joked about finally working with Leo, "Yeah, I had a restraining order against him for a while... incident in ’94 we don't like to talk about."
