So, i remember back in the day, James Bond movies became increasingly silly and campier, until Mike Myers came with Austin Powers, and it kinda flunked the real ones for a while until they decided to retry a more serious style with Craig. I feel the same happened with Scary Movie sending teenage slashers to hide in a corner for a while.
So… Why has no one tried a superhero spoof? At this point this shit writes itself, and it might give us a superhero respite?
… This is a kinda shower thought. But still.
Super starring Rainn Wilson
Mystery Men starting Ben Stiller and William H. Macy
The Incredibles
Also check out non-Western cinema superhero movies if you want just a fresh take and not necessarily a parody. The Krrish movies and Hanu Man from Indian cinema are first to mind. They do sometimes embrace/subvert/parody American superhero film tropes.
