I met him, briefly
It was so long ago and so UNremarkable I'm wary of saying it really happened. But it was at a record/CD/VHS store in Chicago in the happening part of the Near North Side. What WAS remarkable was that he looked exactly like he does on screen. He looked like I could I could break a 2x4 over his chest and he'd say "What did you do that for? Are you trying to make me angry?"
But he had tremendous charisma and talent on the big screen. I don't think he was meant to be a leading man. Bryan Brown was much more conventionally handsome in F/X, and I also like him as an actor, so it was obvious who was the chick bait. But Dennehy seems like a very crafty actor, that is to say, a man who knows his craft.
