Fred Claus, Santa's bitter older brother, is forced to move to the North Pole to help Santa and the elves prepare for Christmas in exchange for cash. /// Of the two Claus brothers, Fred (Vince Vaughn) is the troublemaker and polar opposite of his saintly sibling, Nicholas (Paul Giamatti). When Fred's criminal ways finally land him in big trouble, Nicholas bails him out and brings him to the North Pole to work off the debt by making toys. The headaches mount for St. Nick, who not only must deal with his troublemaking brother, but also an efficiency expert who has come to evaluate Santa's operation.
"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." — Fred Claus
