Jesse Heiman is an American extra who has appeared in almost 50 productions, usually uncredited, ranging from movies (Spider-Man, The Social Network, American Pie, Old School) to television (Chuck, Glee, Monk, Curb Your Enthusiasm, Arrested Development.) Embedded above is a two-minute video of his many, many cameos.
I actually recognize this guy from Chuck, where he's featured as a Buy More employee most weeks. The guy gets around! I bet casting him is becoming the visual equivalent of a Wilhelm Scream these days. Enjoy!
