Geoffrey Rush. *le sigh* Though I don't find it particularly 'odd' anymore, as the man has a growing, and very dedicated fanbase, and is lovely to those who have met him. (No, I am not among these lucky ladies
) I think I just have a thing for older men, because I love Alan Rickman as well.
Also Michael Emerson. Yes, he plays absolutely batshit crazy/weird characters, but I love him anyways.
