#7. Eminem in 8 MILE (2002)
Apparently, we aren't the only ones who thought Eminem should have stopped acting after 8 Mile. He must have thought so too. Aside from an episode of Crank Yankers (remember that nasty puppet show?) and a voiceover in the 50 Cent video game Bulletproof, he seemed to have retired from film. But now there are reports that he'll be returning in a big-screen adaptation of Have Gun — Will Travel. Oh well, it was nice while it lasted.
