My current crush: William Fichtner. The man's just a few days from 51 years young and is still sexier than most leading 30 year olds on TV (IMO). At first glance, he's not someone you'd classify as conventionally good looking, but he brings such a level of intensity into his character portrayals that he instantly draws you in. Definitely one of the more talented actors out there. Plus, he's got a rockin' bod, a striking pair of sad blue eyes, and a distinctively husky voice. :P And I think his forehead gives him character.
(Worksafe, but just in case -- there are a couple of naked chest shots)
