Image Credit: Mitchell Haaseth/NBCLinda Hamilton will play Chuck’s mom in the series’ new season, it was revealed at the start of the show’s panel. “Are we happy with this?” asked co-creator Josh Schwartz. Wild cheering ensued.

Guest star Olivia Munn will play Greta, a new Buy More exec, in the season premiere. But Munn will be only one of many rotating guest stars who’ll each manage the Buy More for an episode, now that it’s become an owned-and-operated CIA outfit.

“The search for Mom will be a big part of season four,” said Schwartz. “We’ve also learned about putting people between Chuck and Sarah.” So rest assured they will remain a couple. The panel commenced with a video of Jeffster performing Lady’s Gaga’s “Bad Romance.” Schwartz said jokingly that he’s been thinking of a Chuck spin-off: “Jeffster On The Lam,” he said, a new kind of adventure series.

If the panel — which included all the show’s stars, plus co-creators Schwartz and Chris Fedak — could be said to have a fan-fave, it was probably Adam Baldwin, who was showered with cheers and laughs at his every raised eyebrow. He also came in for some ribbing from his fellow cast-members. When Baldwin mentioned his Joss Whedon series Firefly, the cast rolled its collective eyes and someone remarked, “There he goes again, talking about his old shows.” Clearly, this is a cast that had bonded rock-solidly.
