Just one day after six new cast members signed on for HBO's Westworld, the show has added a whopping eight more actors, lead by James Marsden.

Based on the 1973 film Westworld, the show is set in a futuristic theme park where visitors can live out their wildest fantasies, with the help of androids, although the robots soon start killing off the patrons. James Marsden will play Teddy Flood, a charming yet mysterious new arrival to a small frontier town, who is proficient with his revolver. He pursues a local woman which sends him on a dark journey.

Eddie Rouse has also joined the cast as "Kissy," which is short for his full Indian name Kisecawchuck. He runs the town saloon while controlling the contraband trade, with his work at the bar has made him an expert in card games.

They join previously-confirmed cast members Anthony Hopkins, Evan Rachel Wood, Jeffrey Wright, Rodrigo Santoro, Shannon Woodward, Simon Quarterman, Angela Sarafyan and Ingrid Bolsø Berdal.
