CineFix makes their arbitrary choice of the best movie end credits in five different styles. Along the way, it's a pretty good survey of the history and styles of end credits. Lots of honorable mentions, though a few good ones inevitably got left out.
If you don't have time to watch, here are their choices:
1) Blue Valentine
2) Legend of the Drunken Master
3) Ferris Bueller's Day Off
5) Inland Empire
