The camera pan from Craig and Hammerhead to Amy was meant to be a whip pan. The camera operator's mistake went unnoticed by the director as his character was dead in the shot, so couldn't see the camera/camera operator.
The conversation at the start of the short film was meant to be longer, but footage was lost resulting in the final version of the scene.
Raad uploaded the bloopers to YouTube before uploading the short film.
