Punch-Out: Behind the Punch is a Hugh Janus documentary. Doc, Glass Joe, King Hippo, and of course, Little Mac are all interviewed. They discuss three of Mac's fights; Glass Joe, King Hippo, and Tyson. They also discuss the rumors of Mac abusing drugs to give him a little extra for the Tyson fight and other off beat topics.
The only problem I have with the movie is if you use Scene Selection the music doesn't play, no biggie. Punch-Out fans and fans of comedy in general should enjoy it.
