Last night, Westworld, HBO's newest series about a theme park resort full of questionable people and artificial intelligence, premiered.
While the show is based on the 1973 sci-fi film of the same name, there are quite a few differences between the original movie and the new series. Most of those changes come with the modern revamp — everything looks much more sleek and less medicinal than it did in the original — but there are a few changes that are pretty easy to spot.
It was through a conversation about the premiere last night that the original trailer was rediscovered and it’s pretty interesting to watch if you’ve seen the pilot for the new series already. Aside from the tonal differences, the way that artificial intelligence was imagined back in 1973 compared to how it’s been reimagined by executive producers J.J. Abrams and Jonathan Nolan is wild.
Of course, because the show is based on the film, there are plenty of similarities that people will be able to point out, like the amount of cowboys and animatronic animals running rampant through the fake Wild West setting. But even then, there are some pretty big differences between how Michael Crichton imagined the cowboys should appear (think Clint Eastwood) and how Abrams and Nolan thought the residents of Westworld should dress (think Little House on the Prairie).
The full three-minute trailer for the film can be seen above. The premiere of Westworld is currently available to stream on HBO Now and HBO Go. Westworld airs Sunday nights at 9 p.m. ET.
