What do you do when a movie star refuses to be in your movie? You do like Martin does, you film the star anyway. Martin has decided he will shoot some scenes with Murphy in them. Of course, Murphy doesn't know he is in them. The rag-tag actors Martin has will act around Murphy, using their lines at him and letting his reaction move the film along. In the action star's absence, Martin has to use Kit's geeky twin Jiff, who Murphy also plays, quite well as a matter of fact.

Steve Martin wrote the script and has some very effective scenes. Some of them are laugh out loud worthy. It's not as funny as the previews suggest. Some of the jokes misfire, as with any comedy. The script feels like a seesaw, the big laughs go up, but then they go back down, and up again, and down again.

The scene-stealer in the movie has to be Heather Graham, who is bent on becoming a star in a hurry, preferably in a week. She'll do anything, including sleeping with just about everyone who is on the set, to get to the top. Her character is very likable, even if she wasn't hot.
