The Movie: 1999's Thicker Than Water
The Rapper Behind It: Mack 10
Why It Was Bad: Mack 10. Okay, okay, so we'll cut the guy a little slack. He was asked to fill a role that he wasn't really ready to fill. But because of that, this film about rival gang leaders trying to launch a career in music (Fat Joe was also in the film) was pretty much doomed from the start.
