Fred Claus (2007)
1 visible crew/equipment mistake
Directed by: David Dobkin
Starring: Elizabeth Banks, Paul Giamatti, Vince Vaughn, Miranda Richardson, John Michael Higgins
Revealing mistake: In the beginning when Nick gets a present from Fred you see that the background is fake.
Fred Claus: Nick, there's been one thing that's been eating at me since I've been here. That Naughty-Nice List that you got? There's no naughty kids, Nick. They're all good kids. But some of them are scared. And some of them don't feel listened to. Some of them had some pretty tough breaks too. But every kid deserves a present on Christmas.
Trivia: Siblings Anonymous features three real brothers of celebrities: Frank Stallone, Roger Clinton, and Stephen Baldwin.
