HBO's mysterious Westworld sent fans into a tweeting frenzy last week after the first sustained peek at the long-delayed sci-fi Western, which upgrades Michael Crichton's 1973 androids-run-amuck thriller for the new millennium, debuted on HBO. Totally reengineered by executive producers Jonathan Nolan (Person of Interest) and Lisa Joy (Pushing Daisies), Westworld tackles the promise and the threat of artificial intelligence (hey, even Stephen Hawking and Bill Gates say they're truly worried about it) in a lawless R-rated play-scape where a theme park's guests' darkest desires run wild. Only this time, you'll find yourself sympathizing with the sentient bots who are slave-laboring under the creepily apathetic gaze of Dr. Robert Ford (Anthony Hopkins). The resulting future-shock series resembles a mash-up of Blade Runner, Ex Machina, Black Mirror, and Crichton's own Jurassic Park; but its creators initially struggled to get their prime-time machine operational.
