STAGE TUBE: Sneak Peek at Season 5's CHUCK on NBC

Everyone's favorite secret agent is back in the one-hour action-comedy series. Chuck Bartowski (Zachary Levi, "Alvin and the Chipmunks: The Squeakquel") returns as a regular guy who also happens to be the government's most vital secret agent.

Now that those closest to Chuck know his secret, he must try harder than ever to keep his spy life from interfering with his personal life. But this has never been more difficult -- his relationship with superspy Sarah Walker is getting serious, and he's about to take on his most personal mission yet: finding his mother.

This season, Chuck's assignments take him far from Burbank, with each mission bringing him closer to uncovering what happened to his mom, Mary Elizabeth Bartowski (guest star Linda Hamilton, "The Terminator," "Terminator 2: Judgment Day").

The ever stoic Colonel John Casey (Adam Baldwin, "My Bodyguard," "Serenity") returns with partner Sarah Walker (Yvonne Strahovski, the upcoming "The Killer Elite"), one of the CIA's top agents and Chuck's new girlfriend.

Also starring are: Joshua Gomez ("Without a Trace") as Morgan Grimes, Chuck's best buddy; Sarah Lancaster ("What About Brian?") as Chuck's ever-supportive sister Ellie; Ryan McPartlin ("Living with Fran") as Devon Woodcomb (also known as "Captain Awesome"), Ellie's husband. Chuck's Buy More team consists of Big Mike (Mark Christopher Lawrence, "The Pursuit of Happyness") and the Nerd Herd, which includes Lester (Vik Sahay, "Time Bomb") and Jeff (Scott Krinsky, "The O.C.").

CHUCK premieres on NBC on October 28, 2011.  To get a sneak peek at the upcoming season, click below!
