A nerdy computer whiz on 24, a brain-stealing serial killer on Heroes and Tori Spelling's gay best bud on So NoTORIous: this up-and-coming small-screen actor is nothing if not versatile. Intrigued by acting from an early age, Quinto began appearing in Pittsburgh Civic Light Opera productions as a child. But he decided to pursue acting as a vocation after being involved in a car accident at age 16. After high school, the dark and handsome player studied at Carnegie Mellon's prestigious acting conservatory, and a year after graduating, he began landing guest spots on diverse series, everything from Touched by an Angel to CSI. His recurring role on the third season of 24 upped his profile, but 2006 was his breakthrough year. Although his first series-regular gig on So NoTORIous was cut short when the campy show failed to get picked up for a second season, he quickly snagged his signature Heroes role. With his icy stare and monotone delivery, Quinto proved a breath-taking villain, and producers announced that he would become a series regular during the sci-fi smash's second season.
