Bowfinger

Bowfinger is a movie starring Steve Martin, Eddie Murphy, and Heather Graham. When a desperate movie producer fails to get a major star for his bargain basement film, he decides to shoot the film secretly around him.
On the verge of bankruptcy and desperate for his big break, aspiring filmmaker Bobby Bowfinger concocts a crazy plan to make his ultimate dream movie. Rallying a ragtag team that includes a starry-eyed ingenue, a has-been diva and a film studio gofer, he sets out to shoot a blockbuster featuring the biggest star in Hollywood, Kit Ramsey -- only without letting Ramsey know he's in the picture.
