The Marvel Cinematic Universe is expanding at a rapid rate. With nine films established in the canon thus far, and three more in the filming, production and development stages respectively, here's a franchise that has already reached an insanely huge size., which is impressive, given that it's only been around for a mere six years. To add to that, there have been some (possibly) joking comments from Marvels President, Kevin Feige, regarding Marvel's plans for the next decade and a half, which basically means that the studio are going to need to hire a hell of a lot more actors to fill their quota.

Take the upcoming Guardians of the Galaxy, for example: you could certainly argue that Bradley Cooper is wasted on simply voicing Rocket Racoon instead of playing an actual character in another film.
