14. Edward Norton
Despite not getting a chance to be in The Avengers, Edward Norton is still one of the most recognizable and versatile actors in Hollywood. He broke out in the late 1990's when he starred in two of the defining films of the era in Fight Club and American History X. His performance as racist skinhead Derek Vinyard in American History X earned him an Academy Award nomination and the character is often considered one of the best of the 90's. Norton showcased his versatility as an actor in films such as 25th Hour, The Incredible Hulk, Leaves of Grass, and Moonrise Kingdom. In Leaves of Grass, he plays both a philosophy professor and his drug dealer brother. In Moonrise Kingdom he played a boy scout leader that is the complete opposite of most of the roles he had done previously. Norton has a reputation as an actor who is hard to work with, but he is definitely one of Hollywood's most talented actors.
