Most of the time the first film is always an origin story. Even the reboots are origin stories. I would make a film that is ongoing in the life of the superhero. Stan Lee had the right idea with the reality show Who Wants To Be A Superhero. I would not make a parody or some wild R Rated film that not a lot of kids could see. Let's see -- John Wayne as Jonah Hex! Val Kilmer as Green Lantern!
