Creator Cameo: Director James Gunn plays Satan (or Demonswill) in The Holy Avenger's public access television show.
Doing It for the Art: It is a very low-budget independent film, so everyone involved was paid scale.
Dueling Movies: With 2010's Kick-Ass, which had a similar premise of dark, realistic superheroics. Super is even darker and more grounded in reality. Both Mark Millar and Gunn are friends in real life, with the former defending the latter's work when accusations of copying came up (both films were developed around the same time independently of one another). Millar even screened Super at his own Kapow! comic convention in London. There's a third movie to factor into this with Defendor, which played at festivals before either film came out. Super could be considered half-way between Kick-Ass and Defendor, or maybe even more similar to the latter in many aspects.
