The whole concept of Two Face still being alive was due to the fact that, yes, in a superhero movie, people can survive bigger falls than that. In fact, I see that as a cheap way of killing him off. They might as well made him have a heart attack. But sucks that Nolan isn't on for another one, that means that they will probably make another one with a shitty director and have stupid Jolie as cat woman and be a bastardization to the storyline.
