Season two introduced a creepy new all-white robot. “The drone hosts are down in another facility; they function as sort of worker bees and it was fun to build out that idea. That was one of those situations where you read the script for the first time and you weren’t quite sure what you were going to make. It’s this host that doesn’t have any skin and doesn’t have any pigment and it’s all muscle.

“Justin Raleigh and his team at Fractured FX really did an amazing job. They were able to find a very slim person to put on the [drone host] suit; it looks like normal proportions when he puts on the suit. From the FX standpoint, all we did was cleanup on the suit itself. Where there’s a crease or where it doesn’t look like it’s their skin-cleanup on makeup effects.”

There were new animal characters as well. “We did a tiger sequence for episode three, which obviously had its challenges, doing full CG tigers on a TV schedule,” says Worth. “But the team at Rhythm & Hues busted it out and killed it as always. It was a lot of fun to work with them and bring this to life.”

Different progressions of Westworld’s Interactive Map are also seen in Season 2. “We tried to find ways of showing this technology that’s not doing as well. What does the map look like when it’s malfunctioning? What does the map look like when there’s a battle in the world? We built up the technology in season one. It was based on a projector system but we always wanted it not looking like a projector, not looking like a TV screen and not looking like a hologram. So we had a map upon which we projected real time imagery of this landscape and it was all based on correct lighting, so at different times of day the shadows across the map would be different, with a three-dimensional quality. This season is about what happens when the map goes south. The systems are all shut down and because of that the map breaks, the map comes back online, the map dies.” Worth had to figure out what that looks like “from a story perspective and from a visual effects perspective as well.”
