Australian actress Yvonne Strahovski became an overnight sensation in the United States as Agent Sarah Walker on the well-loved but perennially ratings-challenged action-comedy series "Chuck" (NBC, 2007-2012). The striking and athletic actress more than fulfilled the role's requirements as a tough but beautiful agent pressed with protecting Zachery Levi, who had accidentally gained possession of government secrets. But Strahovski also brought a great deal of comic timing, as well as vulnerability to the character, which helped her expand into other television and film roles before and after "Chuck's" finale. Though initially assigned to the "girlfriend" position in "Killer Elite" (2011) and "The Guilt Trip" (2012), Strahovski proved her versatility with turns as an accused killer on "Dexter" (Showtime, 2006-13) and on stage in a Broadway revival of "Golden Boy." Subsequent leading roles in features like the action-horror hybrid "I, Frankenstein" (2013) pointed to Strahovski's ascension in the Hollywood market from TV player to feature film star.
