"I think it would be really interesting with the age-old Batman/Superman conflict, because they are two different sides of the same coin and their methods are entirely different. And I think it would actually make for an interesting story as to why, first of all, they were going head to head and how. I think that would make a great story."
When asked if this movie is actually in the works, Henry Cavill offered this response.
"Who knows, I'm sure there's all sorts of ideas being thrown around at Warner Bros right now."
While we have not seen a live-action team-up between the Man of Steel and The Dark Knight, the heroes have been seen together in animated films such as Justice League: The New Frontier, Justice League: Doom, and LEGO Batman: The Movie - DC Superheroes Unite, which was released on Blu-ray and DVD this week.
Warner Bros. also has the superhero ensemble Justice League, which would likely feature Batman, Superman, Wonder Woman, The Flash, and many other DC heroes, in development, but it isn't known when that project will go into production.
