Isaiah Washington appearing on CW pilot

A former “Grey’s Anatomy” star is headed to a CW post- apocalyptic thriller.

Isaiah Washington will be one of the stars of “The 100,” which is based on upcoming Alloy books written by Kass Morgan.

The project is set 97 years after nuclear war destroyed civilization. A spaceship harboring the last human survivors sends 100 juvenile delinquents back to Earth for the chance of re- colonizing the planet.

Washington will play Jaha, leader of the last humans now inhabiting the space station in orbit.

Henry Ian Cusick (“Lost”), Bob Morley (“Home and Away”), Eli Goree (Emily Owens, M.D.”), Marie Avgeropoulos (“Cult”) and Eliza Taylor (“Neighbours”) round out hthe cast.

Leslie Morgenstein and Gina Girolamo from Alloy TV serve as executive producers alongside Matt Miller (“Chuck”) and Jason Rothenberg. Rotherberg also wrote the script.

Washington has also appeared in “Bulworth,” “Hollywood Homicide” and in “Wild Things 2.” He faced controversy in 2006 after he reportedly insulted co- star T.R. Knight with a homophobic slur. Whether related or not, ABC announced the following June that it was not renewing Washington’s contract, and he was going to be dropped from the show. He later classified his dismissal as an “unfortunate misunderstanding.”
