Holy crap, I just finished watching "THE KING OF KONG" from 2007:
http://www.imdb.com/title/tt0923752/and it's no doubt one of the best movies I have seen lately! :-O
Actually it's more like a documentary, not just a movie. Dealing mostly with the recent battle for the world-record in Donkey Kong highscore, and also gives great insight into the beginning of the video gaming competitions in the 80s in general.
Highly recommended to everyone here.
If you liked the "Masters of Doom" book, you'll also love this flick.

Hell, one of these guys is even wearing a Doom (3) shirt...
Enjoy!
