The TV casting news is in full force today. First up, EW reports that Gregory Itzin, the once deceptive president of 24, has signed on for another government role as the actor will join the cast of Big Love as a pivotal politician. Itzin will take on the major recurring role of Senator Richard Dwyer, the Republican Majority Leader of the Utah State Senate. And since series lead Bill Paxton has just become a member of the State Senate, you can be sure they’ll be having plenty of interaction once the series starts production for its fifth season sometime this week.

Hit the jump for casting additions to The Good Wife, Detroit 1-8-7, Criminal Minds: Suspect Behavior and the prequel series Spartacus: Gods of the Arena.
