Stephen Dorff in Blade
David Boreanaz and James Marsters in the tv show Buffy.
Alucard from the Hellsing anime
Yes, I've always had a thing for Stephen Rea in Interview with the Vampire but Antonio Banderas is also gorgeous.
Bill Paxton in Near Dark (I like my psychos)
Kiefer Sutherland in Lost Boys
Vincent Perez in Queen of the Damned and Tayler Kane (the vampire at the Admirals Arms who was kind of the leader of the trio that wanted to hurt Jesse but Lestat chased them off). Tayler just struck me as so seductive. Maybe it was his voice.
I can't help myself. I love them all.
