To create the infomercials that appear on Harry Owen's TV screen in The Glitch, the filmmakers studied hours of late night television and decided it was impossible to write anything more absurd. The medical professionals appearing on Harry Owen's TV screen are speaking an amalgam of dialog adapted from 'real' male enhancement products.
The Glitch composer Laurent Watteau, impressed by actor Scott Charles' vocal talents, created a theme song for Scott's character, Harry Owen, to sing at a crucial moment in the film. Scott recorded the vocal while listening to music playback, seated in a makeshift sound-proof cubicle in producer Joe Fordham's bathroom. The finished song appears briefly in the film as an homage to corny action movie ballads.
