Linda Hamilton teases 'Chuck' role

Linda Hamilton has revealed details of her role as Mary Bartowski in the fourth season of Chuck.

The actress, who made her first appearance on the NBC comedy-drama in last night's season premiere, described the character as "a force to be reckoned with".

"Mary Bartowski is the absentee mother of Chuck and Ellie and the most that I can really say about her is that... she is not your ordinary homemaker," Hamilton told TV Squad. "She disappeared because she was deep undercover as a spy. So she comes back into Chuck's life with an agenda and... she is definitely a strong, forceful [woman]."

Hamilton admitted that viewers expecting an emotional reunion between Chuck and his mother would be disappointed.

"It ain't all apologies and sentiment, that's for sure," she claimed. "[Mary] has her own agenda and it just kind of goes crazy from there."

Chuck continues on Mondays at 8/7c on NBC.
