Even though he may be a little old for me, I have to say Al Pacino is a fine-looking man.
My other picks are Chris Meloni, Jesse L. Martin (Det. Green on "Law and Order"), Danny Masterson (Hyde on "That 70's Show"), Ewan McGregor, Robert Plant when he was younger, and Trent Reznor.
And while I admit George Eads is hot, but Gary Dourden (Warrick) and Eric Szmanda (Greg) are way hotter.
