  • StageCraft is a visual effects technology built around a massive LED video wall, and it has changed the way film and television productions create the worlds around their actors. The system was designed by Industrial Light & Magic for the Disney+ series The Mandalorian, and the soundstage where it lives is called The Volume. What makes this technology striking is what it replaced: actors no longer stand in front of flat green screens waiting for a world to be painted in around them after the fact. Instead, they step inside a cathedral of high-definition light, and a living, computer-generated landscape wraps around them in real time. How did a problem on the set of a different film set this whole chain in motion? And how quickly did what began as a single custom stage expand into a network of permanent facilities across three continents?

  • Greig Fraser, the cinematographer on Rogue One in 2016, ran into a string of difficulties during that shoot. Those frustrations planted a specific idea: that large LED screens could serve not merely as decoration but as a functional component of the set itself. Fraser's instinct found traction with a team that included Richard Bluff and Rob Bredow from ILM, along with Kim Libreri of Epic Games. The collaboration brought together expertise in filmmaking, visual effects, and real-time game technology under one roof. Jon Favreau, the director of The Lion King in 2019, separately worked with ILM to develop tools that would help him visualize shots inside a fully computer-generated space. When Favreau moved on to create The Mandalorian for Disney+, ILM recognized the convergence: the technology was ready, and the director was already comfortable enough with virtual environments to use it.

  • The StageCraft process places live-action actors and physical set pieces inside a surrounding shell of enormous, very high-definition LED video walls. Those walls display computer-generated imagery that would previously have been composited onto the footage only after the principal photography was finished, using chroma key screens as a stand-in. The shift matters because the camera sees the background the same way the human eye does, picking up natural reflections and lighting from the panels rather than from a green placeholder. When the camera moves, the production team can realign the background instantly to match the new angle. The entire computer-generated environment can be manipulated in real time, giving directors and cinematographers an immediate sense of how a location truly looks. To handle that real-time three-dimensional rendering, ILM turned to Epic Games' Unreal Engine, a game engine already well established in the interactive entertainment world. Technology partners FuseFX, Lux Machina, Profile Studios, Nvidia, and ARRI each contributed specialized capability to the broader system.

  • For the second season of The Mandalorian, ILM advanced the technology to what it called StageCraft 2.0. The updated version came with a physically larger volume, expanding the space actors and cameras could inhabit. More specialized software accompanied that growth, and the most notable piece was Helios, a rendering engine that ILM designed specifically for StageCraft hardware. Helios was not an adaptation of an existing tool but a purpose-built system, reflecting how tightly the demands of the volume had outpaced off-the-shelf solutions. The iterative step from the original setup to StageCraft 2.0 within a single series illustrated how rapidly the production team expected the technology to evolve once it was in regular use.

  • In September 2020, it was announced that a second permanent volume was being built at Manhattan Beach Studios in Los Angeles, separate from the original one constructed for The Mandalorian, with a completion target of March 2021. At the same time, a volume at Pinewood Studios in London was set to open in February 2021. A larger, custom facility was also announced for Fox Studios Australia. Each of these new volumes was designed to be bigger, to use more LED panels, and to deliver higher resolution than the original Manhattan Beach installation. ILM also maintained the ability to assemble temporary, pop-up virtual production configurations in locations that lacked a permanent stage. A volume for Vancouver was announced in November 2021, with plans to open in early 2022. That expansion across Los Angeles, London, Sydney, and Vancouver traced the path of an infrastructure shift rather than a single invention: StageCraft had become a platform that major productions on multiple continents could schedule into their shoots.

  • The list of productions that adopted StageCraft spans genres and studios far removed from The Mandalorian's origins. On the television side, The Book of Boba Fett, Obi-Wan Kenobi, Andor, Ahsoka, and Star Wars: Skeleton Crew extended the technology within the Star Wars universe. Outside that franchise, House of the Dragon, Percy Jackson and the Olympians, Doctor Who series 14, Avatar: The Last Airbender, How I Met Your Father, and Our Flag Means Death each brought the volume into their own production workflows. Feature films followed a similarly wide path: Thor: Love and Thunder, The Batman, Black Adam, Ant-Man and the Wasp: Quantumania, The Marvels, The Creator, Transformers One, and The Fabelmans all shot at least some material using StageCraft. Productions scheduled as far out as 2025, including Tron: Ares and A Big Bold Beautiful Journey, confirmed that the pipeline of committed projects extended well past the technology's first years. Steven Spielberg's The Fabelmans, a film explicitly about the mechanics of filmmaking, choosing to use StageCraft stands as one of the more pointed endorsements in that list.

Common questions

What is StageCraft and who designed it?

StageCraft is an on-set virtual production visual effects technology built around a high-definition LED video wall. It was designed by Industrial Light & Magic (ILM) for the Disney+ series The Mandalorian. The soundstage where it is implemented is called The Volume.

What inspired the creation of StageCraft?

Cinematographer Greig Fraser encountered multiple issues while shooting Rogue One in 2016, which gave rise to the idea of using large LED screens as part of the set. The concept was developed further by a team that included ILM's Richard Bluff and Rob Bredow, as well as Kim Libreri of Epic Games.

How does StageCraft work on set?

StageCraft surrounds live-action actors with large, very high-definition LED video walls displaying computer-generated imagery in real time. The background can be realigned instantly as the camera moves, replacing the traditional approach of compositing backgrounds in post-production using chroma key screens. ILM uses Epic Games' Unreal Engine to handle the real-time three-dimensional rendering.

What is StageCraft 2.0 and what is the Helios rendering engine?

StageCraft 2.0 was an upgraded version of the technology introduced for the second season of The Mandalorian. It featured a larger volume and more specialized software, including Helios, a rendering engine designed by ILM specifically for StageCraft hardware.

Where are the permanent StageCraft volumes located?

Permanent volumes were announced at Manhattan Beach Studios in Los Angeles, Pinewood Studios in London, Fox Studios Australia, and Vancouver. The London volume was planned to open in February 2021, the second Los Angeles volume was expected to complete in March 2021, and the Vancouver volume was announced in November 2021 with an early 2022 opening planned.

Which TV series and films have used StageCraft?

Television series using StageCraft include The Mandalorian, The Book of Boba Fett, Obi-Wan Kenobi, Andor, House of the Dragon, Ahsoka, Percy Jackson and the Olympians, Doctor Who series 14, and Avatar: The Last Airbender, among others. Feature films include The Batman, Thor: Love and Thunder, Black Adam, The Fabelmans, Ant-Man and the Wasp: Quantumania, The Creator, and Tron: Ares.
