Mandalorian’s VFX Team Blends Puppets, LED, and Stop Motion

John Knoll’s – VFX supervisor John Knoll explains how “Star Wars: The Mandalorian and Grogu” builds its worlds with LED volumes, miniatures, a handcrafted sensibility, and stop-motion artistry—plus a last-minute plan to put a real performer on set for a key role. The result

The first time you realize how intentional it is, it’s not in the biggest explosion—it’s in the reflections.

In “Star Wars: The Mandalorian and Grogu. ” VFX supervisor John Knoll says director Jon Favreau’s approach has always been about letting the illusion show its seams when it matters. “Best tool for the job’ — that’s always been the credo for this show,” Knoll told IndieWire. “With the one twist being that Jon [Favreau] really likes having a bit of a handcrafted look.”.

Knoll has worked on “Star Wars” movies as a visual effects supervisor dating back to “The Phantom Menace. ” and he traces this philosophy to what audiences should be allowed to notice. In Knoll’s words. it’s fine if you can tell something is “a puppet” and even “a character in a rubber mask.” It’s fine. too. when a miniature or “a stop motion sequence” is legible—because in Favreau’s mind. the visible artifice is part of the charm.

That mindset extends to the film’s production design and the way it earns its realism, starting with how the show—and now the movie—captures environments.

The Favreau-directed sci-fi spectacle has so far grossed $176 million globally. Knoll described the blend of virtual production techniques with “every trick in the Old-School Hollywood special-effects book. ” including an LED-based system that can generate digital environments by projecting high-resolution imagery onto wrap-around screens.

He also won an Emmy for his VFX work on Favreau’s “The Mandalorian” TV series, which was shot largely within a 110-foot-wide ellipsoid-shaped “LED Volume” in Manhattan Beach.

When Disney expanded the world into a standalone feature centered on intergalactic bounty hunter Din “Mando” Djarin (Pedro Pascal) and sidekick Grogu, aka Baby Yoda, Knoll’s work shifted into building a new way to shoot the Razor Crest spaceship.

From the beginning of the series. Knoll says. he’d wanted an LED volume for filming miniatures—and for the movie they built an 8-foot-by-8-foot LED cube with one face open. specifically so reflections and lighting could land in-camera. Knoll had “this gorgeous 48-inch model of the bare metal ship. ” and he pushed that detail into how the crew planned shots. If the Razor Crest was “flying amongst clouds. ” Knoll says they made sure “you’re seeing clouds reflected on the side of the ship.”.

He also explained that the approach affected how Mando was captured. “We would shoot Mando in the LED environment, instead of [in front of] blue screen, to get all those reflections on his highly polished armor.”

Knoll collaborated with production animation supervisor Hal Hickel—who oversaw digital characters including Rotta the Hutt—and with Legacy Effects puppeteers. in charge of Grogu. Together. they created a virtual travelogue of exotic planets. including the snow-capped mountains that backdrop Mando and Grogu at the start of the film.

The mountain imagery traces back to real-world location scouting. “We knew one thing: It’s mountainous with pine trees,” Knoll said. Andrew Jones, the production designer, identified an area north of Vancouver called Mount Waddington as the base for the environment. Knoll’s co-supervisor. Justin van der Lek. then went up there for a four-day helicopter scout-and-shoot. photographing “thousands and thousands of stills.” Knoll said “a lot of the imagery you see in that opening is Mount Waddington.”.

Not every destination relied on LED screens and virtual backdrops. Some environments were built as massive physical sets, including the Blade Runner-like cityscape Shakari.

For Shakari, Knoll said they found a big industrial warehouse in downtown LA and built the main drag there. “We can see way off miles into the distance. ” he said. and instead of using a blue screen at the end of the street for the digital extension. the team built LED screens at both ends and used motion tracking cameras to generate the street extension. Knoll called it “a nice use [of LED volume] where it’s not a 110-foot diameter round set.”.

In Shakari, Mando and Grogu meet Hugo, a gregarious four-armed food truck vendor voiced by Martin Scorsese. Hugo was ultimately computer-generated, but Knoll wanted the production to keep the scene grounded. “When you’re doing synthetic characters. Hal and I strongly believe you should cast an actor to play that role on set if at all possible. ” he said.

Knoll explained what that meant in practice: it helps camera operators frame up. it gives other actors someone to “play against. ” and it helps editors cut the scene. The crew brought in Misty Rojas, a little person, to perform Hugo’s role on set. Knoll said they “didn’t know that Marty was gonna do the voice until the whole scene had been shot and Jon did the deal.” He added. “God bless him — Marty did a hilariously great performance with all that hemming and hawing.”.

Knoll said the team had a camera on Scorsese while he recorded the voice, allowing the production to incorporate “some of his gestures and facial expressions.”

The film also leans into tactile effects during action sequences. One of its more thrilling chase scenes sends Mando racing across dunes—modeled on Nova Scotia’s Magdalen Islands—in a low-flying “speeder” with droid thugs in hot pursuit. Knoll said old-school practical effects made it feel alive. The full-size speeder prop sat on what the crew called an inner tube rig: “this very low-tech. springy mount where some of our grips could shake it around to give it a bouncy motion.”.

When the story turns to its climactic battle—Mando going toe-to-toe with two very tall droids—Knoll brought in Oscar-winning “Jurassic Park” legend Phil Tippett and his stop-motion team. Knoll said Tippett’s crew used a technique “immortalized back in 1933.” He described it plainly: “It’s straight out of ‘King Kong.’”.

In Knoll’s account, the droid puppets were 12 or 14 inches tall and had three arms, lots of moving armor plates, and many articulation points. Knoll said that the Tippett team told him it was “the single most complicated thing they’ve ever done.”

Even the film’s most iconic visual legacy came with a reminder that nostalgia doesn’t always survive modern clarity. Knoll pointed to “Star Wars” canon inspiration. but also to the upgrades the team had to make after he tried to revive the original Stormtroopers look for “Rogue One: A Star Wars Story.”.

He described visiting George’s archive building. where “he’s got a lot of the original ‘Star Wars’ costumes.” When Knoll saw the Stormtrooper helmets in person. he said they looked “like high school craft projects.” The conclusion was blunt: “It was clear that those helmets weren’t gonna hold up. so we made entirely new ones. way more polished.”.

Knoll then explained why the change became necessary. In the era of original filmmaking, fake-looking helmets didn’t draw the same scrutiny—but now “With digital cameras and better projection systems, you can see things more clearly than you could see them before.”

Still, Knoll’s tone stayed on one guiding goal: keeping the audience in the spirit of a classic adventure.

The film’s scope, he suggested, fits within pulp entertainment traditions such as “Flash Gordon” and “Tarzan,” which George Lucas famously admired in his youth. Knoll said he was “pleased that this movie is mostly being received in the spirit intended.”

In his telling, Favreau wanted an old-fashioned adventure where you don’t need to study first. Knoll quoted the director’s attitude toward the homework some people expect: “Oh man. do I have to do a load of homework to enjoy this movie?” Then he said. “No. it’s just sort of a fun adventure you can see without having done 40 hours of homework.”.

“Star Wars: The Mandalorian and Grogu” is now in theaters.
