He didn't look particularly asthmatic or excessively smallish to me. He did have rather thick glasses in Bladerunner, though I thought that was the character rather than the actor.
Maybe with the right makeup team, proper lighting and camera angles, he could play one in the epic film.
I'd vote for him. Maybe this epic movie could be kickstarted?
How old is Joe now, anyway? Is he still working? Who is his agent?
