Zach Roerig, 'The Vampire Diaries'
You know him as: Lone Mystic Falls human Matt Donovan / Why we like him: Matt Donovan finally has something to do on "The Vampire Diaries" other than being the show's sole human, and Roerig has happily risen to the challenge. Now that a witch has possessed him, Roerig has the fun job of playing one character who's impersonating another. It's not an easy task, but it's one that Roerig makes both entertaining and convincing. / Where else you've seen him: Cash on "Friday Night Lights," Hunter on "One Life to Live" and Casey Hughes on "As the World Turns."
