Men in Black

1. Will Smith
Will Smith seems to glide from success to success without much effort. He's a big presence. When he walks into a room, you know he's there. In addition to hits such as "Ali," "Men in Black" and "Hancock," he cares about family and affecting the future. Committed to ... morethe charity Malaria No More, he has traveled to Africa with his family to witness the devastation the disease can cause. "I think a large part of why I've been successful is that I have, essentially, a white-collar career with a blue-collar mentality," he says. "I can never really relax. I'm always waiting to see what's next. It's always, 'OK, something different is gonna happen here.'" Next month he stars in the drama "Seven Pounds." "I believe that the guy who works the hardest generally wins," Smith says. "Nelson Mandela once told me that when he was in prison, he was able to watch one American film every six months. He said our films are about hope and what the world should be. He told me to keep doing exactly what I'm doing, because there's a struggle somewhere that I'm helping. I got really inspired by that."
