4. Mel Gibson
Known for his angry tirades, Mel Gibson would make an excellent Hulk. Forget CGI, all you need to do is put Mel Gibson on-screen with some green body paint and everyone would get the idea. Perhaps it would be a good idea to keep some Jewish people and paparazzi on set so that Gibson can have some fuel for his uncontrollable anger, bringing some real authenticity to the character.
Eric Bana would be interesting. Plus many fans say Eric Bana makes the best looking Hulk/Bruce Banner. Eric Bana will definitely be fit to be in the MCU. Also Eric Bana would look good in any Avengers Movie, and Crossoverfilms.
