I am a lot younger than Brad but that doesn't matter, he is still sexy as all hell! lol :) ... and getting better with age.
Brad Pitt is a excellent actor who can play serious roles as well a comedic roles. He really gets into the roles he is playing and seems to put a lot of passion into the more dramatic roles. I enjoy watching him in both.
Fame and being the "sexiest man alive" does not seem to have gone to his head (too much!) and he just seems to be a likable guy.
Although some may disagree I think he has handled the media well over the years.
