I have a thing for voices. If a man has got an incredible voice, whether speaking or singing voice, I am all over the floor. Hence why some of my favorites are Alan Rickman, Jeremy Brett, etc. I <3 Jeremy Brett's voice super much. AHH and Jeremy Irons and Liam Neeson!
Others I adore include Cary Grant (he always seems to have this smirk on his face, I love his subtle humour), Clark Gable ("It Happened One Night" is simply hilarious), Jimmy Stewart (it's his boyishness), Gregory Peck (certainly one of the most attractive men, EVER). Fred Astaire, Frank Sinatra, John Lennon, George Harrison, Ralph Fiennes, despite that scandal with the stewardess. I'm spacing at the moment, of course, but I there's more, of course. Oh, right, I almost forgot, Michael Caine. I don't know why, but yes. Michael Caine.
I also adore three-piece suits. Something about waistcoats, they make anybody look automatically more sexy.
Edited to add pics + some people I forgot to mention earlier. lol.
