2. It's a Wonderful Life (1946)
What good is a Christmas Countdown without a Christmas classic?!
Jimmy Stewart stars as George Bailey in this moralistic movie about a man who thinks the world would be a better place if he didn't exist. Cue Clarence (Henry Travers) the angel on a mission to convince Jimmy otherwise and earn his wings.
Suicide and money troubles aside, It's a Wonderful Life is the ultimate feel-good movie directed by the masterful Frank Capra. And Capra and Stewart both cited it as their favourite of the films they were a part of and that's got to count for something.
The film was released later in colour but I wouldn't recommend it. A little bit of charm is lost with the bringing of colour technology to this film. The black and white version the original and just the way it's meant to be.
If you haven't watched the film and don't want to see the ending avoid watching the clip below... Even though it is brilliant.
