Showtime’s “House of Lies” has added more famous faces, tapping John Cho and Malcolm-Jamal Warner as guest stars for one episode of its upcoming season.

Cho will play Sean Chew, a messianic billionaire CEO of a revolutionary retailer who has radical philosophies about organizational structure. Warner will play his suffering COO, Yurgen Celebi, who calls upon his old business school friend, management consultant Marty Khan (Don Cheadle) and his team to save Sean’s company from himself.

Created by Matthew Carnahan and based on Martin Kihn’s memoir of the same name, “House of Lies” also stars Kristen Bell, Ben Schwartz and Josh Lawson. The 10-episode fifth season of the series will premiere in 2016. It was recently announced that “Scrubs” alum Donald Faison will also guest star that season.
