Today’s the day for respected film actors to commit to TV, it seems. Hot on the heels of Ethan Hawke negotiating to topline a CIA procedural for Fox, Don Cheadle has signed on for House of Lies, a new Showtime pilot from Matthew Carnahan (Dirt). He’ll star as a “highly successful, cutthroat management consultant who is never above using any means (or anyone) necessary to get his clients the information they want,†in the project, which is based on Martin Kirn’s nonfiction book, House of Lies: How Management Consultants Steal Your Watch and Tell You the Time.
