HBO drama pilot Westworld is building one of the largest and highest-wattage casts in recent memory. Ed Harris has closed a deal for one of the central leads in the project, from J.J. Abrams’ Bad Robot, Person Of Interest creator Jonathan Nolan, writer Lisa Joy, producer Jerry Weintraub and Warner Bros TV. He joins previously cast Anthony Hopkins, Evan Rachel Wood, James Marsden and Jeffrey Wright. Inspired by Michael Crichton’s 1973 sci-fi movie set at an amusement park, Westworld is described as a dark odyssey about the dawn of artificial consciousness and the future of sin. Harris will play The Man in Black — the distillation of pure villainy into one man. This marks Harris’ return to HBO where he starred in the movie Game Change, winning a Golden Globe and earning an Emmy nomination. He will next be seen in the feature film Run All Night. Also cast in Westworld to date are Rodrigo Santoro, James Marsden, Shannon Woodward, Ingrid Bolsø Berdal, Angela Sarafyan, Simon Quarterman, Eddie Rouse, Demetrius Grosse, Kyle Bornheimer, Currie Graham, Lena Georgas, Steven Ogg and Timothy Lee DePriest.
