The Angry Video Game Nerd: Cooper. If you want to be a nerd like me, you gotta make some unique sacrifices. No physical fitness, no social popularity and most important, no girls.
Revealing mistake: About seven minutes in, during the scene where we see Cooper helping the Nerd as a cameraman, you can tell that Cooper has been added to the scene using green-screen effects, as the actor was unavailable to shoot at the location. The lighting on Cooper doesn't quite match the lighting of the scene, and you can see a slight "blur/feathering effect" around him where the greenscreen background was removed.
