“He can play a weasel bad guy like no other.”
Mostly a weasel...I wonder where he gets his inspiration? ;>)
I think his looks do help. I am not saying he looks bad, but he does have a distinctive look about him.
And his bad guys are not just over the top parodies. He can be a weaselly worm, a smarmy a$$hole, or downright evil. And he is believable.
He can also play other roles as well.
