For the third season of "Chuck," it's no more Mr. Nice Spy! The Chuck (Zachary Levi) you know -- the hapless Nerd Herder hopelessly devoted to sexy super spy Sarah (Yvonne Strahovski) -- has morphed into a super spy guy. With the new Intersect 2.0 in his brain, he's now a master martial artist whose brain is locked and loaded for action-packed fun. Also new this season: The addition of a dashing rival (Brandon Routh) to the team, someone from Chuck's Buy More life discovers his secret and Chuck learns the spy biz can turn the nicest guy dark and dangerous. Bonus material includes the featurettes: "Chuck-Fu … and Dim Sum: Becoming a Spy Guy," "The Jeffster Revolution: The Definitive Mockumentary," declassified scenes, and a gag reel. All 19 episodes are included on five discs for the DVD; four for the Blu-ray.
