CBS' hit series The Big Bang Theory has never shied away from bringing in high-profile guest stars, with William Shatner, Bob Newhart and even real-life nerd heroes such as Stephen Hawking and Steven Wozniak appearing on the show through its first nine seasons. Today we have word that the show's high-profile guest star tradition will continue with Breaking Bad star Dean Norris coming aboard for a multi-episode arc in Season 10. The actor will appear in the first three episodes of the new fall season.

Entertainment Weekly reports that Dean Norris is playing Captain Williams, described as a "tough Air Force representative from the Department of Materiel Command, who's interested in the boys' quantum gyroscope for military applications." You may recall that, in the Season 9 finale, Wolowitz claimed that the Air Force might be spying on their gyroscope project. Here's what showrunner Steve Molaro told EW about this story line, before Dean Norris' casting.

"Based on what we've learned and what we've been researching, it could be fine, but I think there is a small percentage chance that they should actually be concerned. That storyline is certainly not finished. They have no choice but to see what the Air Force wants and then go from there."

Dean Norris, who also starred on CBS' Under the Dome, won't be the only famous guest stars stopping by this season. We reported last month that Katey Sagal and Jack McBrayer have come aboard to guest star as Penny's (Kaley Cuoco) mother and brother, who come to town for Leonard (Johnny Galecki) and Penny's "re-do" wedding. The Season 10 premiere will also explore the "awkward morning" after Sheldon's (Jim Parsons) mother (Laurie Metcalf) slept with Leonard's (Judd Hirsch) father in the Season 9 finale.

In related news, back in June, series star Kunal Nayyar hinted that this upcoming season may in fact be the final season. CBS had renewed the show for a whopping three seasons back in 2014, and this season is the last of that order, and despite Kunal Nayyar's comments, other cast members such as Kaley Cuoco expressed confidence that the show would return. During CBS' TCA summer tour presentation today, CBS president Glenn Geller was just as confident that the hit sitcom would continue past Season 10.

"We are very confident that everyone involved wants more Big Bang past Year 10. I know Warner Bros will make those deals... We'll put it on for as long as everyone wants Big Bang on the air. I hope it lasts forever."

Like it has for the past few seasons, The Big Bang Theory will start off Season 10 on Monday nights, due to CBS' Thursday Night Football, kicking off on September 19 at 8 PM ET. The show will then move to the Thursday 8 PM ET time slot on October 27, after the network's Thursday Night Football run comes to an end. Stay tuned for more updates on The Big Bang Theory as we get closer to the Season 10 premiere.
