Indiana Jones is cool. The Bride is cool. So is Ash, Sanjuro, Han Solo, James Bond. But this poll neglects the coolest character with the longest running film career. That is, of course, Godzilla.
Good old Snake. Just oozing puddles of cool. Watch out for that... lemme go get a mop.
Seriously. I think at least part of this vote is affected by my view of the actor. Before Escape from NY, Kurt Russell invariably did nerdy types in disney-esque movies. (The Computer Wore Tennis Shoes, the voice of adult Copper in the Fox and the Hound...)
Snake was a departure from his norm, and he pulled it off WELL.
I like Ash and Han of course, but Dirty Harry's my favorite on that list. He somehow manages to live in that strange land of LN, not quite LG and not quite LE, a force of nature to be sure.
