Iconic actor Robert De Niro has signed up to star as a movie producer in new independent film WHAT JUST HAPPENED.

The RAGING BULL Oscar-winner's character struggles to hold onto his morality in unscrupulous Hollywood, and is reportedly based on ART LINSON - who produced hit movies Fight Club, HEAT and The Untouchables.

What Just Happened producer JANE ROSENTHAL says, "The movie will capture Hollywood just as WAG THE DOG captured Washington."
