Josh Hartnett, Lucky Number Slevin/The Black Dahlia

Josh Hartnett knows only too well that in Hollywood hot hunks can cool off pretty quickly. That's why this 27-year-old former teen idol has learned to take control of a career that saw the Minnesota college student skyrocket out of obscurity at 18 when he floated in front of Sofia Coppola's cameras for 1999's The Virgin Suicides. And that's why the tall, rangy actor has opted now for offbeat, risky fare like Lucky Number Slevin (a hipster-gangsta murder mystery that teams him with Morgan Freeman, Lucy Liu and Sir Ben Kingsley) and the 1940s-set Brian De Palma noir The Black Dahlia (with his girlfriend Scarlett Johansson, Hilary Swank, and Aaron Eckhart). And he played a father for the first time in Resurrecting Champ. That's a long way from teen idol land (17 minutes).
