I am one of those very rare people who are attracted to someone intellectually first. I don't particularly care about looks, but I tend to prefer interesting over conventionally good looks and I'm not at all consistent. This is very difficult for me. So in no particular order:

Adrien Brody
Wittgenstein (younger)
Lewis Powell (conspirator)
Daniel Day Lewis
Boris Pasternak
Johnny Depp (sometimes)
Stanley Kubrick (young)
William Butler Yeats

Yay! I did it.
