In a recent email to the Seattle Perl Users Group mailing list, Tim Maher, lord high pooh-bah of SPUG provides the following:

In order of appearance, the actors are: Jon Orwant, Casey West, Abigail, Elaine Ashton, Jarkko Hietaniemi, Dan Sugalski, Michael Schwern, Simon Cozens, Uri Guttman, Damian Conway, Larry Wall, Mark-Jason Dominus, Nat Torkington, and then Uri again.

Update samtregar is correct. This refers to Nat Torkington's YAPC 2002 Movie reported above by VSarkiss. I responded to the wrong node.
