CINDERELLA MAN star Paul Giamatti will team up with Vince Vaughn and play SANTA CLAUSE in an upcoming holiday comedy. The Christmas tale revolves around Santa's bitter, black-sheep brother, played by Vaughn, who returns home to the North Pole after a long absence. The movie was previously titled Fred Claus, but due to a copyright issue, the film will be re-titled. DAVE DOBKIN will direct the film after previously working with Vaughn on Wedding Crashers.
