Christina Robinson, 'Dexter'

You know her as: Astor, Dexter's (Michael C. Hall) adopted daughter and Cody's (Preston Bailey) older sister

Why we like her: As much as the rebellious, bratty kid can be a cliche, Robinson's portrayal of a teenage girl whose mother has just been murdered felt incredibly honest to us. Somehow it works that she's the confidant and challenge to a serial killer who has a surprisingly gentle side.

Where else you've seen her: In a bunch of film shorts, including "Equestrian Sexual Response." She also has a twin sister, Courtney, so perhaps you think you've seen her on "Tim and Eric Awesome Show, Great Job!" as the girl in the B'owl commercial.
