The Westworld finale is a super-sized 90 minutes long and is directed by Nolan himself (who also helmed the show’s pilot).
Westworld season 2 isn’t expected until 2018. Previously, HBO’s entertainment president Casey Bloys told us regarding the showrunners’ pitch for the next round of episodes: “I didn’t know exactly what to expect in season 2. And what [Nolan and Joy] came up with is as exciting, mysterious and as fun as season 1. And completely original, as well.”
