I've got one in mind, whom I'll share later, but which actor do you think has played the most bad-ass characters. I don't mean playing a character who was the baddest, but who plays different bad-asses over and over?
In leading roles, perhaps, but I suspect that there's someone who's played a lot of small parts in a lot of films that I probably don't know the name but I see his face and think "Yeah, that's whathisname. He was in that other movie that I can't remember the name of..."
Vin Diesel has made almost his whole career playing 3 bad-asses -- Riddick, XXX, and the dude in Fast & Furious. The character from Knockaround Guys who claimed to have been in 500 street fights was a monster too.
