OK, I've been pondering this, but I honestly do find those I already listed very hot. Clooney especially. He definitely has what I like:

Hmmm, alright, here are a few more that might not be such mainstream picks:
Terrence Howard
Harrison Ford
Jason Schwartzman
Owen Wilson and, although he's fairly mainstream, his brother Luke, whom I should have included on my previous list
Jamie Foxx
Kurt Russell
Alec Baldwin
Orlando Bloom
