8. Jim Carrey - All In Good Taste
The Movie: An up-and-coming and uptight filmmaker is disheartened to hear that the only way anyone will bankroll his wholesome project about an orphaned boy and his dog is to add a bunch of nudity and violence.
The Role: Carrey, playing an assistant nude photographer for the movie (that's a photographer of nudity, as well as a photographer who is nude), and appears for all of three minutes. Though the rubber-faced actor has no lines, he makes quite the impression during his lone scene by showcasing his insanely gaunt physique.
His scene is played for laughs, but you'd be forgiven for believing it to be a horror picture after having to endure a long look at his tiny, pasty buttocks.
