The hype keeps building for next Summer's 'The Avengers', featuring Marvel heavy hitters Iron Man, Captain America, Thor and more. But lost in all of the hype has been one little--okay, big, green guy: Hulk. Thanks to Marvel releasing the final character production poster today at SDCC, fans can REALLY get excited. The first look at Mark Ruffalo's Hulk is pretty awesome. Also, Marvel released a full set poster of the Avengers, featuring Captain America, Iron Man, Thor, Hawkeye, Black Widow, Hulk, Nick Fury and other S.H.I.E.L.D. operatives. Check out the images below.
