These montages each December (video embedded below) always get to me. For a classic movie buff, it's hard to say goodbye to many of the actors and actresses who have given me hours of entertainment throughout my life. It's also fun to remember some of those great performances as the montage plays.
Update 12-22-10: YouTube pulled the account of the embedded video, but Turner Classic Movies on YouTube still has it, only it can't be embedded. So follow this link to view it.
