Mark McKinney, Rhys Darby Join Lauren Graham in ‘The Z-Suite’

Tubi is filling out the cast for its Lauren Graham-starring workplace comedy The Z-Suite with new guest stars.

Rhys Darby (Flight of the Conchords), Mark McKinney (Superstore), Dani Kind, Nadine Djoury, Richard Waugh and Peter Keleghan have nabbed guest-starring roles. They join earlier-announced series regulars Graham, Madison Shamoun, Nico Santos, Spencer Stevenson, Anna Bezahler and Evan Marsh in the comedy shooting in Toronto.

The Tubi original is set at a boutique New York ad agency where generational divides see the established C-Suite and rising Gen Z employees clash. After a company decision spirals out of control, the agency’s reigning executives are forced out and replaced by Z-Suite employees, whose skills and patience are tested.

Graham will play Monica Frazier, an ad agency mogul who is fired as CEO and has to claw her way back into the company she helped build. In the latest casting announcements, McKinney will appear in the comedy as George, CEO of Boppin’ Burger and the ad agency’s biggest client, while Darby guest stars as a sardonic, successful ad executive who always knows best.

Kind appears as an assistant to the CEO at Atelier ad agency, while Djoury is the HR manager. Waugh is a longtime employee and Keleghan owns Atelier. Kate O’Brien writes The Z-Suite and serves as showrunner, while Graham executive produces Tubi’s first original live-action series.

“It’s incredibly exciting to see The Z-Suite come to life with such an amazing roster of talent. Having them on board and witnessing their brilliant comedic performances has truly been a gift,” O’Brien said in a statement.

Lance Samuels, Samantha Levine, Daniel Iron, Eric Wattenberg, Gary Vaynerchuk and Matt Higgins also executive produce. Tubi has global distribution rights to the series.
