HBO has cast Ed Harris and James Marsden in the pilot for their upcoming new series Westworld. It's inspired by Michael Crichton’s 1973 Western thriller, and it's described as "a dark odyssey about the dawn of artificial consciousness and the future of sin."
Harris will play one of the central leads in the story known as The Man in Black, "the distillation of pure villainy into one man." Marsden is will play a character named Teddy Flood, "a mysterious new arrival to a small frontier town. Teddy quickly proves both his charm — and his talent with a revolver — while his pursuit of a local beauty launches him on a dark odyssey." Eddie Rouse has also joined the production and will play Kissy, "a laconic American-Indian who deals cards and contraband from the town saloon."
The movie is being produced by J.J. Abrams' Bad Robot, and is being written by Jonathan Nolan. The remaining cast includes Anthony Hopkins, Evan Rachel Wood, Jeffrey Wright, Rodrigo Santoro, Shannon Woodward, Ingrid Bolsø Berdal, Angela Sarafyan, and Simon Quarterman.
