After adding a slew of new cast members last week, HBO's Westworld has brought on Ed Harris for a pivotal villain role.

The actor will be playing a character known only as The Man in Black, who is described as, "the distillation of pure villainy into one man" by The Hollywood Reporter. He joins a cast that includes Anthony Hopkins, Evan Rachel Wood, Jeffrey Wright, Rodrigo Santoro and James Marsden, just to name a few.

The story is inspired by the 1973 feature Westworld, which was the directorial debut of author/filmmaker Michael Crichton. The original film was set at a theme park where visitors can live out their wildest fantasies through the use of android robots, although something goes awry and the robots begin hunting the humans. This version is described as a dark exploration into artificial intelligence and the future of sin.


Jonathan Nolan and Lisa Joy wrote the pilot script and will executive produce alongside J.J. Abrams, Jerry Weintraub and Bryan Burk. No production schedule was given for the pilot.

Ed Harris recently starred in Snowpiercer, and he will next be seen in Frontera and Run All Night. The actor also starred in the HBO TV movies Game Change and Empire Falls.
