'Westworld' casting switch: 'Narnia' star replacing 'Once Upon' actor

There’s a casting change behind the scenes on HBO’s Westworld: Actor Eion Bailey (Once Upon a Time) is leaving the sci-fi thriller a week after he was announced as joining the show. A scheduling conflict emerged before Bailey started, and now Ben Barnes (The Chronicles of Narnia franchise) is taking over the role of Logan.

The character is described as a “louche bachelor and veteran Westworld guest. His hedonistic romp through Westworld is equally motivated by self-indulgence and a desire to help his friend, William.”

Westworld stars James Marsden, Evan Rachel Wood, Thandie Newton, Anthony Hopkins, Jeffrey Wright and Ed Harris in the series version of Michael Crichton’s techno-thriller about androids run amok at a fantasy-fulfilling theme park. Previously, actress Miranda Otto left the series after shooting the pilot after her character was re-conceived, and joined the fifth season of Showtime’s Homeland. The show is planned for 2016.
