Angus Sutherland as Walter??
Well, the chances of a movie on this game happening are slim to none, but hey, you never know. But I think if they ever did do a movie on SH4, they should get Angus Sutherland to play Walter. I saw him in "The Lost Boys 2" (not the best movie ever, but that's not the point) and I was really startled by how much he reminded me of Walter. I honestly could see him pulling it off. He's the only actor I've seen so far that's reminded me of Walter. His character in LB2 has got this pleasant demeanor, but you can tell there's more to him than what he's displaying. Seemingly placid, with a hint of underlying menace. Plus he looks like Walter, being tall and handsome with longish blonde hair.

He doesnt have too many pictures (all of those are from LB2) but you really have to watch the movie to see what I'm talking about.
