Yeah, without wishing to further derail this thread from Stewart, I think it shows true professionalism and a real love of acting to throw himself so wholeheartedly into a role, when he must have had a clue that this wasn't the next Citizen Kane he was in.
He truly became Bison, which is more impressive considering that Bison isn't exactly flowing with deep layers of character. Turned him into a very human tyrant.
If only there had been a few more actors like him in it, a good script, a decent budget, and a dozen other things done right, Streetfighter could have been great.
