Brad Pitt in kalifornia and Fight Club, Vin Diesel in Pitch Black and Fast and Furious, Norton in American history X (yes it is possible without roids) Mark Walberg in Big Hit, Nick Cage-those are the guys who are not typically associated with body building
AS for the bodybuilders-Stalone in Get Carter, looks bigger than ever. Jean Cladue Van Damme about 10-5 years ago, he's not looking so built this year.
But i think the strongest most muscular guys are:
the dude from green mile
the guy who plyed spawn, he was also in universal soldier2, exit wounds and totally ripped in the jerry springer movie
