Joaquin Phoenix!

He's also an extremely talented actor, which makes him even sexier. I only watch "Gladiator" for him and fast-forward to his scenes. And he's great in lots of movies: "Walk the Line", "Quills", "Signs"... And so self-deprecating - another reason why he's so hot.

No one does sexy-creepy better than him. Anyone who saw "Red Eye" should know what I mean; that scene with him slamming Rachel McAdams against the walls in the tiny airplane bathroom was one of the sexiest scenes I've ever seen in movies. Seriously.
Also,
Eric Bana, Ewan McGregor, Clive Owen, Marat Safin, Hugh Jackman...and a lot of other people mentioned on this thread.
But three that weren't mentioned (and are way too old for me; actually most of these people are
Hugh Grant - my first celeb crush!
He has a good line in charm; never mroe charming than in "About A Boy" or "Bridget Jones's Diary."
Tom Cruise - I know everyone thinks he is crazy (including me), but I still think he's really good-looking, especially for his age. Plus, I've met him at a premiere before, and he's a
really nice guy.
Al Pacino - He's old now, but I still find him totally charming. And he was hot hot hot during his prime. Watch "The Godfather."
Eric Bana will always be Poida to me
