I found it at auctrix_icons, some time ago :) I have no idea who are the actors, I would like to know it too ;) Judging from their poses it is "Carpe Noctem" scene from TdV, but I don't know any production in which Black Vampire wears such shirt. Maybe it is not "Tanz der Vampire" at all... Now when you said it, this guy looks like Thomas, but I'm also not sure.
