NEW YORK - OCTOBER 21:  Actor Mandy Patinkin speaks at the 2009 Princess Grace Awards Gala at Cipriani 42nd Street on October 21, 2009 in New York City.

The actor joins previously announced star Claire Danes.

Mandy Patinkin has officially joined Showtime’s new pilot, Homeland.

He joins previously announced Claire Danes, who plays CIA officer Carrie Anderson, and will fill the role of Saul, a veteran CIA Division Chief who is Carrie’s boss and mentor.

Homeland, a Fox 21 production, is loosely based on Gideon Raff’s Israeli television series Prisoners of War, and will be executive produced by Raff, 24’s Howard Gordon and Alex Gansa (24, The X-Files). It centers on an American soldier who is taken prisoner during the Iraq invasion in 2003. The solder returns to the States after years captivity. Danes’ character Carrie is a driven CIA officer trying to fight her own psychological demons and is convinced that intelligence that led to the solder’s recapture was all a set-up.

The pilot, written by Raff, Gordon and Gansa, begins production in January.

Patinkin most recently starred in CBS’ Criminal Minds.
