Aging Action Stars

Matrix no more! Keanu Reeves may have found success with the "Matrix" series, but he has moved on and traded in his role as a futuristic messiah to play a man in blue. Reeves stars as a Los Angeles police officer in the thriller action flick " Street Kings," which opened April 11. The 44-year-old shot bullets at fake human targets as he trained with real cops. "Then I understood what a loaded weapon can do," he told Parade Magazine. Despite his police training and martial arts skills, he's not ready to fight in real life. "I've learned there's always someone badder than you," he said. Reeves isn't the only action hero in his class primed for a comeback. Check out who's still going strong and who's hung up the towel.
