On the left is the original skit from Saturday Night Live that inspired the film, "Night at the Roxberry." This skit also features Jim Carrey. Night at the Roxberry Features Chris Kattan and Will Ferrell.
Kattan has been with SNL for many years and has appeared in several movies as either an guest extra or as the main star himself. Yet he is best known for his amazing dance moves on the dance floor.
