Big news for fans of NBC’s Chuck came on Saturday at the 2010 San Diego Comic-Con as the actress set to play Chuck’s mom in season 4 was revealed, and it’s none other than Linda Hamilton (The Terminator). In a show that has prided itself on having a lot of popular guest stars may have topped itself with this casting. Creators Chris Fedak and Josh Schwartz spoke about the upcoming season and how the main plot running through the season will be Chuck’s (Zachary Levi) search for his mother.

If you ever get a chance to come to SDCC, I highly recommend checking out the Chuck panel, as it’s always a good time. This year’s panel opened with the Hamilton announcement and then cut into a performance by series band Jeffster dancing to Lady Gaga’s “Bad Romance“. Then the cast was introduced and discussed the upcoming season as well as their yearly “Thank You” to the fans. If you’re a fan of the show, you always feel very appreciated after seeing one of their panels, and you can tell that this is a show with a very passionate fan base.

Other news revealed at the panel was a list of other guest stars in the first few episodes of the series, including Olivia Munn, Dolph Lundgren, the return of “Stone Cold” Steve Austin, and Isaiah Mustafa, better known as the Old Spice Guy. Mustafa and Munn will both play CIA agents who come into the Buy More to oversee the operation of Team Bartowski, and each episode will have a different guest going by the same character name.

Unfortunately, the panel was running too long and was cut off before any of the fans could ask any questions, much to the chagrin of everyone at the panel. It may have been a short panel, but it was definitely sweet.
