Rapper Chris "Ludacris" Bridges has joined the cast of the Warner Bros. Pictures' Vince Vaughn comedy FRED CLAUS, says The Hollywood Reporter.

David Dobkin is directing the film, which stars Vaughn as Santa's loser brother living in New York who returns home to the North Pole and almost ruins Christmas. Ludacris will play an angry elf. Paul Giamatti, Kevin Spacey, John Michael Higgins and Elizabeth Banks also are in the cast.

Ludacris was part of the ensemble cast of Crash and received a SAG Award for outstanding performance by a cast in a motion picture. He appeared in Hustle & Flow and on TV's "Law & Order: SVU." He recently did voice work for an episode of "The Boondocks" on Cartoon Network's Adult Swim.
