"The Big Bang Theory" is going to break bad in Season 10, thanks to guest star Dean Norris.

Norris, who played Walter White's (Bryan Cranston) brother-in-law and DEA agent Hank Schrader on the AMC series "Breaking Bad," will have a multiple-episode arc on "TBBT" as Captain Williams, an intimidating Air Force officer who's interested in acquiring Howard (Simon Helberg) and Leonard's (Johnny Galecki) quantum gyroscope to use for military purposes. Very good casting, since Norris looks like the idea of an Air Force general.

The casting brings Norris back to CBS, where he played the nefarious Big Jim Rennie in CBS' "Under the Dome" for three seasons.

"The Big Bang Theory" returns Monday, Sept. 19 on CBS.
