Feast your eyes on the first images of Olivia Munn’s guest spot on Chuck! Munn (Perfect Couples, Attack of the Show) will appear on the NBC show’s fourth season premiere as a CIA officer, code name “Greta”, but as you can see from these pictures, her cover is a member of the Nerd Herd squad.

As previously reported, this role of Greta will change hands through the season to former WWE Diva, Stacy Keibler, and to Isaiah Mustafa of Old Spice advert fame. Now that the CIA has taken over the Burbank Buy More, the dynamic of the store will be very different indeed!

Chuck premieres on NBC, Monday, September 20, 2010.
