Many kids dream of being a superhero when they grow up. Unfortunately, no amount of money can make a crime-fighting bat work or build an Iron Man suit (believe it, <a href="http://vt.co/sci-tech/innovation/elon-musks-list-things-year-2030-absolutely-crazy/">Elon Musk</a> has probably tried), and a radioactive spider bite will probably send you to the hospital rather than give you the proportional strength of an arachnid. However, there are people who come close to being a superhero by embodying them on the big screen. Now that the sub-genre has taken over cinemas, we've managed to see plenty of behind-the-scenes shots of what it's like for these actors to play the comic book characters. 1.

Although, it must be pretty cool to be walking around in full-costume, especially when you get to surprise kids with an appearance.
