Director Jon Favreau (Iron Man, The Jungle Book) hasn’t been shy about embracing new technology for filmmaking. While producing The Mandalorian for Disney+, he was one of the first filmmakers to use ILM’s massive LED screens, AKA “The Volume,” to produce more realistic lighting and backgrounds on studio sets. For the feature film The Mandalorian and Grogu, which hits theaters May 22, Favreau recently revealed that he had Disney build an Apple Vision Pro app to preview its full IMAX scope during filming.

“So I’m making an IMAX movie, and I’m looking at a TV screen, and no matter how big your TV screen is it’s not an IMAX screen,” Favreau said in a recent episode of The Town podcast. “We built software so that I can pop on my Apple Vision Pro and be sitting in an IMAX movie theater and see the full aspect ratio when we’re lining a shot up. And I can watch that take and see what people will see.”

Favreau isn’t the first director to use the Apple Vision Pro — Wicked filmmaker Jon Chu also used it to handle post-production work — but he’s the first to specifically mention using the headset for IMAX production. That’s still a relatively limited use case for the Apple Vision Pro, but it’s one that could be useful to future filmmakers. With its large field of view and sharp micro-OLED screens, the Apple Vision Pro is one of the only ways to replicate the experience of watching a large IMAX screen at home. (The Meta Quest 3 comes in as a close second.)

In general, Favreau says he’s more excited about using existing consumer technology in the filmmaking process than AI. He mentions using the Unreal Engine to previsualize special effects on The Mandalorian and his previous films, and he believes the quality from game engines could be good enough to make it into final productions down the line.

“This is what the animation industry has understood from the beginning,” he said. “Get it right before you ever paint a cel.”
