If you can even find a dvd of Steven Speilbergs's short-lived tv series "Amazing Stories", try to find the episode entitled "Mummy Daddy", where he plays a small part as "Willie Joe"
It's not the best role he ever did, but he did somewhat of a humurous turn as your archetypical rural pickup truck driving redneck. For some reason that role has stuck in my mind, and it still amuses me to think about it. I too have seen him in a lot of films, and his appearance in "Mummy Daddy" is typical of how his screen appearances were at that time(see: "Enemy Mine")

I agree, he's terrific in Blade Runner, Leon was a great character, I also liked him in Striking Distance.
Second chances are rare man, you shoud learn to take better advantage of em'
