Dear rappers: Please. Stop. Acting.

Ludacris

The Mistake: "Fred Claus"

Scenario: Fred Claus, Santa's older brother, begrudgingly moves to the North Pole.

Rapper-Turned-Failure: Ludacris' carefully sculpted observations in "Crash" were pretty annoying, but as DJ Donnie, the North Pole's record spinning elf, Ludacris makes "Crash" the movie look like "Crash" the television series.
