As previously reported, former 24 star and current Covert Affairs recurring player Gregory Itzin is coming to Big Love.
The veteran actor will play a senator who, based on a recent interview with TV Guide, clashes often with the main character of Bill Henrickson.
"I am very judgmental of him because of what he did," Itzin told the publication. "I feel he betrayed his constituents. He told them one thing and then did another."
Meanwhile, Christian Campbell has been cast on the show. The former NCIS and CSI: Miami guest star will portray a high school math teacher who has Cara Lyynn as a student.
