Jeffrey Dean Morgan Joins 'Extant'

Supernatural alum Jeffrey Dean Morgan has joined the second season of CBS's summer drama Extant.

He'll play J.D. Richter, a womanizing cop who's more mercenary than police officer. Freewheeling, hard-drinking and reckless, Ritcher believes he's seen everything until he meets Molly Woods (star Halle Berry).

From Steven Spielberg 's Amblin Television and CBS Television Studios, the series follows Woods, a female astronaut whose recent trip to space has unwittingly steered the human race toward its destruction. Only she and a mysterious stranger may be able to change the course of fate.

Morgan, best known to Supernatural fans as John Winchester, starred as the Comedian in 2009's Watchmen and as Clay in 2010's The Losers. Following a stint on Grey's Anatomy, he headlined the Starz period drama Magic City.
