What he said was " Almost all of them, with the exception of Superman I think my brother
is going to make a really cool film, but I kind of dont get that character. Hes the closest to an establishment superhero that you get. Occasionally writers and artists have gotten some great material out of that conflict for him, I think most superheroes, certainly the ones that Im drawn to, whether youre talking about Batman or Wolverine or Spider-Man are vigilantes and theyre working firmly on the outside and always running the risk of getting caught."

I thought that it was J Nolan who had pitched the Superman idea to his brother and so when I read him saying this about the Superman character it worried me a bit.
