Where has he....
....Biehn?
Sorry, couldn't resist.
Great actor and cool dude, though.
I do wish he'd get more work.
I'm not sure what he's been up to lately but I do know he has a role in the next season of Star Wars the Mandalorian.
He had some outstanding leading roles in the 80's ie Terminator, Aliens, and Abyss(All James Cameron Movies) but for some reason didn't take off as a leading man in the 90's. James Cameron was also perplexed why he didn't get more recognition and better offers.
