Rupert Grint tied with Johnny Depp/Robert Pattinson.
Rupert because he is absolutely gorgeous (in my eyes, don't care if he's a ranga), and he's funny on and off screen, and can actually act. Johnny because ... well, who wouldn't?
Robert because he is quite hairy and oily, and has a hungry look in his eyes that make him seem like the pedophile his character is.
