Edward Norton

Marvel fans would have a hard time picturing any actor other than Mark Ruffalo playing the Hulk, but Edward Norton had the honor of portraying the angry green giant before Ruffalo ever did. Norton appeared as the Hulk in a 2008 standalone film, The Incredible Hulk, two years before the very first Avengers movie would be made.

Marvel revealed that Norton made no effort to get along with his castmates or any of the crew. They phrased it as the actor not having the same “creativity” and “collaborative spirit” as his co-stars. He must not have been surprised when the studio didn’t invite him to be part of the Avengers, given his sour attitude.
