gnat's lightning talk from YAPC::NA 2002 was a film he made entirely during the conference. It is the story of a Python programmer, wandering confusedly around the Perl conference, encountering many luminaries of the Perl community, all of whom are showing off the most severe corner-cases of their personalities.

Best. movie. ever.
