Today is a bittersweet day for loyal 'Chuck' fans, as the show wrapped its final night of filming just a few hours ago. But even though the cameras have stopped rolling, the Buy More lives on -- at least for nine more episodes, the first of which airs tomorrow night (Fri., Dec. 9, 8PM ET on NBC).

AOL TV was on set for the filming of 'Chuck versus the Hack Off,' which was also the final episode of the series that Zachary Levi directed. It guest-stars 'Community' favorite Danny Pudi, 'Lost' alum Eric Lange and ass-kicking 'Matrix' heroine Carrie-Anne Moss, and judging by what we saw during our visit, it promises to be one of the show's most hilarious episodes yet.

We caught up with Moss and Yvonne Strahovski to get the scoop on why Chuck, Sarah and Gertrude find themselves infiltrating a cult; Levi's directing style; and what Strahovski was feeling as the show neared its end. We also have an exclusive -- and revealing -- preview of tomorrow night's episode, so read on for more.
