Elf (2003). I'll admit it. I just never got Will Ferrell until I saw elf. He's childish, but in the best way possible. When holiday stress starts to edge out the good stuff, I pop this dvd into the player and get the joy of the season back again.
Elf (2003) directed by Jon Favreau, starring Will Ferrell, Zooey Deschanel and James Caan. "After inadvertently wreaking havoc on the elf community due to his ungainly size, a man raised as an elf at the North Pole is sent to the U.S. in search of his true identity."
