It's one of the greatest movies ever made, and yet I hear more and more people saying they've never seen it. Well, now you have no excuse.
The entirety of "It's a Wonderful Life" in glorious black and white (no offense*).
Consider this a top-level Teacherdave/PBB recommendation. Watch this before you watch any other film I've recommended to you this year. It's a beautiful film that's unfairly pigeon-holed as a "Christmas" movie. It's not. It's just a masterpiece, no matter what time of year.
