Plot hole: In the scene with the brothers group, the guys don't believe that Fred is Santa Claus's brother (because they don't believe in Santa). But why don't they believe in Santa? Santa leaves gifts for kids on Christmas. If they don't believe in Santa then where do they think the presents came from?

Directed by: David Dobkin
Starring: Elizabeth Banks, Paul Giamatti, Vince Vaughn, Miranda Richardson, John Michael Higgins
Continuity mistake: When Fred gets to the North Pole and the Security elves take him down. Fred comes up and the snow on his face change between shots.
Willie: Charlene, do you think it's possible we can make enough gifts to meet our quota?
Charlene: Baseball bats, lose four seconds, 55... Yeah, it is possible.
Willie: It is, but, Fred, that's not what the kids asked for.
Fred Claus: Yeah, but all that matters is that each of the kids get a toy. That they have something that they can open when they wake up in the morning. Most importantly, they all know there's somebody who's thinking about them.
Trivia: Vince Vaughn plays Paul Giamatti's older brother, despite being 3 years younger.
