Showtime is adding two more shows to its programming slate. The first, Homeland, is an hour-long drama following a CIA agent (Claire Danes) who suspects that a recently rescued American POW (Damian Lewis) is now connected to Al Qaeda. The second, a half-hour comedy, House of Lies, is based on the book House of Lies: How Management Consultants Steal Your Watch and Tell You the Time and stars Don Cheadle as a sleazy, powerful consultant and Kristen Bell as the up-and-comer at his firm. Homeland shares at least a little bit of DNA with Showtime’s 2005 series Sleeper Cell, and Lies should fit right in with the channel’s other shows about horrible people: Dexter, Shameless, Californication, Weeds, Nurse Jackie, Brotherhood, some seasons of The L Word, and so on.
