Let's see, some not mentioned here so far: Klitschko - Excellent feature-length documentary on the two brothers. Very well made. A real rags to riches story. Surprised these guys are still alive having grown up in an area where workers were cleaning up after Chernobyl. Champion (1949) - It is a little cliched by today's standards but not for its time. Probably the first boxing film that followed the now typical "rags to riches to turning your back on your friends and the big fall" storyline that every boxing film after would adopt to a certain extent. Douglas is convincing as a 1940s fighter. And he was fitter than nearly every actor at that time. Sort of the Rocky film of its day.
