As the apocalypse draws near for the Winchesters, the four horsemen align for their time on earth. The latest casting news from the CW’s “Supernatural” lands Matt Frewer (“Eureka”, “Watchmen”, “Max Headroom”) in the role of Pestilence. Exec producer, Sera Gamble gives a bit of context to the arrival of Pestilence:

“Our first brush with him in Episode 520 seems relatively innocuous and then unfolds into something more substantial. Put it to you this way: Horsemen on our show tend to think several moves ahead.”

Thus far, the Winchester brothers have run into two of the four Horsemen. War was played by Titus Welliver (below left) and Famine by James Otis (below right). Death was off-screen in his mention.
