HOUSE OF LIES is the hit half-hour comedy series from the hit tell-all book House of Lies: How Management Consultants Steal Your Watch and Tell You the Time by Martin Kihn. HOUSE OF LIES stars Cheadle (Iron Man 3) in his three-time Emmy-nominated and Golden Globe-winning performance. Kristen Bell (Frozen, Veronica Mars) plays his razor-sharp partner, along with Emmy winner Ben Schwartz (This is Where I Leave You); Josh Lawson (Anchorman 2: The Legend Continues); Emmy winner Glynn Turman (In Treatment); and Donis Leonard Jr. (Criminal Minds). We last left a despondent Marty alone in the desert after a cataclysmic double-cross by Jeannie (Bell) and a visit by the Feds. This season, Marty’s brief stint in white collar prison leaves Jeannie to pick up the pieces of the now tainted Kaan & Associates with Clyde (Schwartz) and Doug (Lawson). Client flight has decimated the bottom line, but Marty is now a man with a singular focus: winning, at any and all cost. Produced by SHOWTIME, HOUSE OF LIES is created and executive produced by Matthew Carnahan. Jessika Borsiczky, Don Cheadle and David Walpert return as executive producers for season four.
