If you are like me, you are probably chomping at the bit for Chuck's Season 4 premiere – coming to your tv sets September 20th.

Comic-Con was wonderful for divulging details on what's going down, along with some pretty nifty (and one not-so-nifty) guest stars. Here's what to expect when this fan-frakkin-tastic season gets under way:

  • S4 will focus on the search for Mama Bartowski. Playing said mama will be none other than Linda Hamilton.
  • In October, Nicole Richie will be reprising her role of Sarah’s high school nemesis Heather Chandler. We hear that she will resurface when a prison transfer goes awry and she ends up being stowed away at Castle. Word on the street is that she will be creating a rift in our beloved Chuck-Sarah romance. (Why wouldn't it?)
  • “Stone Cold” Steve Austin will also be reappearing in the same episode as baddie Hugo Panzer. Stunner anyone?

Also interesting, Zachary Levi (Mr. Bartowski himself) told EW's Michael Ausiello the following: “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.” Hmmm….cool way to go. With this, we will have an Agent named Greta, who will be played by multiple actors, both male and female. First up is my not-so-nifty reference – Olivia Munn. (Sorry, I hate her with a passion, for she lacks any discernable skills.) We will see her in the season premiere. Yay. Also on tap is Old-Spice guy Isaiah Mustafa as Greta V2.0 (really?) as well as former WWE-Diva Stacy Keibler as Greta V3.0. I am interested to see how this character is pulled off.

Newly announced as a guest star is The Incredible Hulk himself, Lou Ferrigno. Lou will be playing  the bodyguard of an evil spy/model played by Victoria's Secret Angel Karolina Kurkova. It wouldn't be a season without some eye-candy spies (more so than Yvonne Strahovski, who we get every episode. ) Both Lou and Karolina will appear in the second episode of the season.

So we have good guests and an interesting story arcs ahead. Season 4 is shaping up to be another great one. I highly recommend that it become part of your Must-Watch List.
