For all his star power, though, Damon is more than just the pretty face of Water.org. He has turned himself into a development expert. This would seem like an obvious and necessary first step for someone embracing the global water crisis as a personal mission. But, in fact, it's highly unusual for a celebrity to dive this deep into a problem this daunting. Whether talking microfinance strategy with rural bankers, giving detailed reports from the field at the annual Clinton Global Initiative, or personally thanking donors like PepsiCo CEO Indra Nooyi, Damon has quietly developed the cred of a program geek.
Damon reads as equal parts hardworking, ambitious, grounded, and caring, the kind of celebrity you'd want your son to be if you had a son who could get both the girl and the point of fame. He's a son who'd make a mother proud. "She doesn't say it quite that way," he says. "It's not the way she talks. She says, 'I affirm him.' Hang on a sec." As he hops out of the car to go pick up the eldest of his four daughters, a charming tween who will never have to fetch water for her family, he smiles and looks affirmed.
Matt Damon "30 Rock"
Why: While Damon could easily put TV in his rearview mirror, he gets in on the joke that is Liz Lemon and has a plenty of fun with it. An airline pilot who keeps his passengers grounded, Damon's career -- on the big and small screen -- is flying higher than ever.
