The first and biggest star to "nope" out of his Marvel marriage was Norton, who played the lead role of Bruce Banner in The Incredible Hulk. Unlike Elba and Portman, though, Norton's creative differences with Marvel proved so severe that the studio itself decided to dump Norton. Luckily for us, they replaced him with fan favorite Mark Ruffalo, while Norton went on to star instead in indie hits like Moonrise Kingdom. This is one breakup that worked out best for everyone—although according to director Louis Leterrier, the whole thing spun out of a disagreement over editing that could have been settled to everyone's liking. "I regret that [Marvel and Norton] didn't come to an agreement where we could've all worked together," he told Entertainment Weekly. "The press is what kept Edward and Marvel from talking to each other. [The argument] was nothing, but then it became something big."
"My feeling was that I experimented and experienced what I wanted to. I really, really enjoyed it. And yet, I looked at the balance of time in life that one spends not only making those sorts of films but then especially putting them out, and the obligations that rightly come with that," Norton later told NPR. "I think you can sort of do anything once, but if you do it too many times, it can become a suit that's hard to take off, in other peoples' eyes."
