 Gunn has said in interviews that he had been working on the script for "Super" since 2002, but he had a hard time getting it made, as producers felt that the content was too violent and esoteric.In addition, Gunn had a hard time deciding on the right actor to play Frank; John C. Reilly was Gunn's top choice, but he wasn't considered to be a big enough star for the film to get made.After "Slither" was made, Gunn had effectively put the project on hold until his ex-wife Jenna Fischer encouraged him to go through with it and recommended Rainn Wilson, her co-star from "The Office".
