“It was just difficult to figure out where I was going to come from with Superman ,” Gunn said speaking to io9 in Los Angeles last week. “And I think that it really started with my dog in a lot of ways.

James Gunn has a penchant for bringing obscure comic book characters to the big screen, and DC's Detective Chimp should be next on the list.
