Westworld season 4 was confirmed a couple of weeks before the season 3 finale aired in May 2020, suggesting that HBO still has plenty of faith in its big-budget sci-fi drama. "From the western theme park to the technocratic metropolis of the near future, we've thoroughly enjoyed every twist and turn from the minds of master storytellers Jonathan Nolan and Lisa Joy," said president of HBO programming, Casey Bloys in a company statement. "We can't wait to see where their inspired vision takes us next." Showrunners Nolan and Joy are back to continue their epic tale – based on the 1973 movie directed by Jurassic Park author Michael Crichton – and, going on past form, it's probably best to expect the unexpected. In its third year, the drama took a hard turn away from the android theme park setting at the heart of the first two seasons, spending most of its time in the human world.
