"Chuck" won't stop at Dolph Lundgren and Olivia Munn when it comes to bringing guests to the show. It has just been announced that Lou Ferrigno, or best known as the voice and body of Hulk in "The Incredible Hulk", will come to the fourth season as a bodyguard.

According to EW, Ferrigno will be starring opposite former Victoria's Secret Angel Karolina Kurkova who portrays an "evil spy model". His appearance is set in the second episode which, if goes according to the schedule, will air on September 27.

Ferrigno's casting came just a day after it was spilled that Stacy Keibler is also a guest. She would be in the third episode as undercover agent named Greta, a character which will be portrayed by different actors every week.

"Greta can be a guy or a girl, which is brilliant," Zachary Levi said. "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. First it was Olivia Munn, who looked hot in her little Nerd Hereder outfit, and [next was] Isaiah [Mustafa], who was a hoot to work with."

The fourth season of "Chuck" begins September 20 on NBC. Nicole Richie and Stone Cold Steve Austin will reprise their roles as Sarah's former high school nemesis Heather and bad man Hugo Panzer respectively.
