PEOPLE's only two-time Sexiest Man (in 1995 and 2000) played Achilles (in Troy), and even his heel was gorgeous. Pitt, who turns 41 on Dec. 18, will heat up the big screen next in Ocean's Twelve. "He's not at all self-involved," says Helena Bonham Carter, who costarred with Pitt in 1999's Fight Club. "He's just a kind and easy and chivalrous gentleman. I know it sounds cliche, but what makes him really attractive is internal – his humor and caring and curiosity."
