Nolan's Cyclops was rushed into a Greek cave in two months and moves better for it
The plan was a full-size puppet with working elbows, wrists and shoulders. What ended up hanging in the cave had none of them, and its single eye was never glued on.
On 13 October 2026, Andrew Jackson, the visual effects supervisor who won an Oscar for Tenet, explained how the Cyclops in Christopher Nolan's The Odyssey was built. The talk, a pre-recorded conversation with Ian Failes of the VFX magazine Befores & Afters, screened at View Conference in Turin, and Variety wrote up the details.
The cave that moved the schedule
The original plan was a more complex full-size puppet, built for a scene expected to shoot near the end of production. Then Nolan and production designer Ruth De Jong found a real cave in Greece, and the Cyclops suddenly had to be ready within months. The team's first reaction, as Jackson remembers it, was "Oh no, we can't do that in that timescale. It's just not possible." His answer was "No, no, no, we're not going to give up."
What he proposed instead was a giant marionette. The rigid sections of the body were built, the elbows, wrists and shoulders were skipped, and the whole thing was hung from cables.
"You could just give it a bit of a push, and the whole thing moved in a really convincing way because of the scale."
— Andrew Jackson, VFX supervisor, The Odyssey
That is the bit nobody planned. A puppet stripped of its mechanics turned out to sway like something heavy and alive.
Two months, halfway up a mountain
Jackson doesn't pretend the deadline was fun. "It pains me to say it," he said of the rush, because getting the puppet "to a cave halfway up a mountain in Greece in two months" was so hard. But the loose, lightweight build gave it a fluidity that a more elaborate mechanical version might have lost, and he put the lesson down to the way Nolan works across every department:
"It's those constraints that force creative solutions that are better than if you have no limits."
— Andrew Jackson
Before anyone files this under "no CGI": the finished Cyclops is a hybrid, and Jackson says so.

The strings did the heavy lifting, but not all of it:
- The body: rigid sections on cables, moved by hand.
- The hands: animatronic, for the moments when soldiers get grabbed.
- The joints: CG, filling in what the marionette left out and augmenting the full-size puppet.
- The eye: Bill Irwin's own.
The puppet put something real in the cave for the actors, the camera and the lighting. The computer finished the job.
Bill Irwin's eye
Irwin, who plays the Cyclops, has form with Nolan and strings. In Interstellar he voiced the robot TARS and physically operated it on set. On The Odyssey, the team was still weighing heavy prosthetics when Jackson filmed him experimenting with the character. Jackson took footage of one of Irwin's real eyes, rotated it and repositioned it in the middle of his forehead, then showed Nolan.
The prosthetics plan lasted until Nolan saw Irwin's own eye on his forehead.
Nolan's reply, as Jackson tells it: "That's how we're doing it. Forget about all the prosthetics. Do that because that's really good." The point, for Jackson, is that the eye never leaves the actor. "All of the performance of this eye is part of his face, and it's all synchronized perfectly," he said. No make-up artist could glue that on.
The same thinking runs through the film: Samantha Morton reshaped Circe's silicone faces with her own hands, in takes lasting a full roll of film.
The Odyssey opened on 17 July 2026 and, by Deadline's count, had taken just under $623 million in the US by 11 October, 13 weeks in and back on IMAX screens. Plenty of that audience has been staring at one eye in a Greek cave without knowing whose it is. Now they know: it's the man who played TARS.
