The Incredible Hulk (2008)

Edward Norton, who had previously rewritten films he starred in, wrote a draft of the script which Louis Leterrier and Marvel Studios found satisfactory in establishing the film as both a sequel and a retcon of Hulk (2003). As Norton explained, "I don't think that in great literature/films explaining the story's roots means it comes in the beginning. Audiences know the story, so we're dealing with it artfully." Norton's rewrite added the character of Doc Samson and mentioned references to other Marvel Comics characters. He also wanted to put in "revelations about what set the whole thing in motion" that would be explained in future installments.
