The Wild West-themed park that Westworld centres on offers plenty for us to try and get our heads around, but it sounds like future seasons will see Guests explore new environments.

In the original 1973 film, parent company Delos operates three areas: Western World, Roman World and Medieval World.

Asked this week whether we’ll ever see the other two, co-showrunner Jonathan Nolan said: I've been coming to New York Comic Con for seven years and I've never said a single thing of substance. They keep inviting me back but I've never answered a single question, not really. Does that answer?"

He was obviously keen not to divulge any spoilers, but later followed up: "You said Roman World and Medieval World, right?" When the fan nodded, he said: “No.”

We can fairly safe assume from this that while those two won’t feature, he and co-creator Lisa Joy are cooking up other worlds.

It makes sense - with Westworld the park being such a success, why wouldn’t the creators turn it into a franchise? They could even use the same robots, a bit like when a video game gets a location-specific sequel using the same character movements/engine.

"For the first season, we only explore the West World," Westworld production designer Zack Grobler told Inverse, but did add: “There's talk about in the future seasons, if there's more, that there will be a different world. But we're not sure what it will be yet."

In Futureworld, the sequel to the Westworld film, there was also a Future World and Spa World.

Nolan and Joy might take inspiration from this, or come up with their own theme. Maybe, just maybe, an in-development park is what is at the end of the maze Ed Harris’ Gunslinger is trying to locate.
