Say hello to the Hulk, the mean, green fighting machine with an anger-management problem. Marvel has just released concept art showing the Hulk's look for 'The Avengers.' His hue this go-round is a lot less cartoony green and a tad more Gollum-esque gray-green, judging by these artist sketches.
He'll be played by Mark Ruffalo in his more peaceful moments, who's taking over the role vacated by Eric Bana and Edward Norton.
