It's no secret that superhero movies are everywhere. While all eyes are currently on the contents of the Marvel Cinematic Universe, the genre goes back way before Tony Stark announced himself as Iron Man. On the DC side of things, there's been quite a few silver screen adaptations, especially when it comes to iconic heroes like Superman and Batman. The latter was mostly recently played by Ben Affleck, but it turns out that a former Bruce Wayne actually discouraged him from taking the role.
