Bell is best known for her work on TV's "Veronica Mars" and "Heroes." Her film credits include "Couples Retreat" and "Forgetting Sarah Marshall."
"House of Lies" was created, executive produced and written by Matthew Carnahan. It is based on the book "House of Lies: How Management Consultants Steal Your Watch and Tell You the Time" by Martin Kihn.
In the small-screen version, Cheadle will star as Marty, a highly successful, cutthroat consultant who is never above using any means -- or anyone -- necessary to get his clients the information they want. Bell will play Jeannie Van Der Hooven, a brilliant, Ivy-League graduate who works at Marty's firm, Showtime said in a news release Tuesday.
The pilot is expected to go into production this month in New York and Los Angeles.
