For a while speculation on whether or not The Hulk will be in ‘Thor: Ragnarok’ has been floating around. Now we can confirm that The Hulk will be in the next Thor film. But just to clarify the main battle the Hulk may be facing will probably not be between The Hulk and Thor but rather The Hulk and Bruce Banner.
Actor Mark Ruffalo who portrays both Bruce Banner and his alter ego (via CGI) The Hulk, had this to say in an interview with the Huffington Post:
If they do appear together will it be in reality or some sort of dream sequence on Asgard where maybe ‘mystically’ they are able to separate and work through some of their problems… or maybe the Hulk will smash puny Banner into a pulpy mush, only time will tell!
