"Superman is the King Daddy of all superheroes; everybody knows that", is how director Zack Snyder put it to a Hall H crowd at this year's San Diego Comic-Con. The reaction in the room was one of muted disbelief. To a world that had experienced The Dark Knight, and was just weeks away from the premiere of the The Dark Knight Rises, it seemed like a preposterous thing to say.
