Lou Ferrigno and Stacy Keibler to Guest on CHUCK August 4, 2010 Chuck, News NBC’s CHUCK continues to fill its guest star roster. Incredible Hulk /Butterfinger Defense League member Lou Ferrigno will appear in the second episode of the show’s upcoming fourth season this September playing the bodyguard of Karolina Kurkova’s model/evil spy character. Additionally, Stacy Keibler has been cast as the third incarnation of Greta (following Olivia Munn and Isaiah Mustafa), a recurring role of Buy More executive/spy that will be played by a different actor or actress each week. When asked about the Greta character, Zachary Levi told Entertainment Weekly’s Michael Ausiello “Greta can be a guy or a girl, which is brilliant. The Buy More has now been taken over by the CIA and it’s a fully functioning operation by the government, so there are these constant agents that are in the store.” Keibler’s episode will also feature the previously announced Nicole Richie and Steve Austin and will air in October. Chuck returns for its fourth season Monday September 20 at 8pm/7 central.
