Where You've Seen Him Before: He played paramedic and war veteran Justin Walker on "Brothers & Sisters" from 2006 to 2011.

Breakout Role: clueless (and soon to be tempted) husband Henry Martin on "666 Park Avenue"

Why: Playing a regular guy who must grapple with demonic forces, Annable brings an everyman sensibility to the role of Henry, providing some welcome grounding as co-stars Vanessa Williams and Terry O'Quinn gleefully chew the scenery. Given how outlandish the concept of the show is, Annable and his co-star Rachael Taylor ("Charlie's Angels") have a thankless task in playing it straight, but having worked with scene stealers like Sally Field, Rachel Griffiths and Calista Flockhart, Annable is up to the task.
