The Celebrity Big Brother winner will star alongside Nick Nolte in a film about a gypsy girl who falls for an Irish-American fighter.
Doherty will play the girl's overly-protective father who gets into a fight with Nolte's character in the movie, which is being produced by Pierce Brosnan.
"I'm going to Hollywood. Can you believe it? I'm getting paid a few bucks. I'm not going to be a millionaire, but I'd do it for nothing," Doherty told the Daily Star.
"It's just an honour to be in it. I love Nick Nolte, God I do. I've always been a fan since he was in Down and Out in Beverly Hills.
"I can't believe I'm gonna knock him out in New York, where I hunt down my on-screen daughter. I'm gonna look him straight in the eye and give it to him."
Brad Pitt was previously rumoured to be interested in making a movie about Doherty's life.
