Australian character actress and playwright Yvonne Strahovski attended the Theatre Nepean drama program at the University of Western Sydney before achieving fame as a small-screen star on series and telemovies in her native Australia. Viewers first caught her on Channel 7's short-lived yet memorable Headland series, then as Martina on the weekly Channel 9 drama Sea Patrol. After a role her her debut feature, Middle of Nowhere, Strahovski heard Hollywood beckoning, and in 2006, she officially moved to Los Angeles. Almost immediately, she signed for a plum role in her first Tinseltown series: the NBC sci-fi comedy Chuck (2007), about Chuck Bartowski (Zachary Levi), a computer nerd-turned-highly unlikely spy. The actress played Sarah Walker, the top CIA agent assigned to work with Chuck, with whom she becomes romantically involved.
