One of my favorite Christmas movies is Elf starring Will Ferrell in the charming role of Buddy the Elf who grew up at the North Pole. His adopted elf father (Bob Newhart) tells him that his real father is Walter Hobbs (James Caan) who lives in New York with his wife and son. Buddy finds his father and meets a great girl named Jovie played by Zooey Deschanel. This fun, heartwarming movie from 2003 is sure to be a Christmas classic.
Here is a clip from the movie with Jovie and Buddy singing Baby, it's Cold Outside.
