The King of Kong (2007) -- Pretty good little documentary about a fairly
normal husband and father who beat the Donkey Kong record of the 80s prick
(Billy Mitchell) who won all those arcade records. But, because the guy
wasn't nerdy enough (or something), they didn't give him credit for it.
The movie is good even if you have no interest in classic video games, since
that's not really what it's about.
