Fred Claus is a comedy film starring Vince Vaughn and Paul Giamatti and produced and directed by David Dobkin. The film is a comedic, holiday film about Santa Claus' older brother Fred Claus.

Project was originally titled "Fred Claus", but was changed due to a potential rights issue. It was then retitled "Joe Claus." After the rights were cleared, the title returned to "Fred Claus."

The wardrobe department consulted Levi's and had special 501's created to accommodate Vince Vaughn's sizes exactly.

David Dobkin was originally going to direct I Now Pronounce You Chuck and Larry (2007), but dropped out to work with Vince Vaughan in ‘Fred Claus’. The two originally worked together on Clay Pigeons (1998) and again in Wedding Crashers (2005).

Kevin Spacey's character Clyde asks for (and later receives) a Superman cape from Santa Claus. Spacey played Lex Luthor in Superman Returns (2006)

Release prints were shipped to some theaters under the fake title "Brotherly Love".
