10 elements from the Superman mythos we'd like to see in a movie
Will we ever see Darkseid, Braniac or Bizarro on the big screen?
This is more of an overall DC Universe mythos element rather than merely a Superman one, but it certainly has ramifications for the Man of Steel. Moreover, though it's a concept that has been arbitrarily convoluted by DC editors over the last decade, the core idea is still very much an interesting one: there are multiple versions of DC's superheroes, including Superman, scattered across multiple parallel universes. It's the kind of thing that, if tapped, nicely disappears the by now annoying term "reboot" as the various incarnations of characters on film could be explained away as part of other universes, allowing for multiple interpretations by filmmakers, just as the original concept allowed for multiple interpretations by artists and writers. And if you want to really get crazy, seeing as there has been contact between the universes on the page, imagine a meeting between Henry Cavill and Brandon Routh (or, for that matter, Michael Keaton, Val Kilmer, George Clooney and Christian Bale).
