“Lion King” (2019) was one of the first movies to involve the Virtual Reality in the process of creation, thus completely reshaping the production pipeline. It all started when the director Jon Favreau was working on the movie “The Jungle Book” in 2016, shooting of which was done in just one warehouse, with use of SimulCam, such that they could see the combination of real-life and CG characters on the screen. Taking it to the next step a set-up for working in Virtual Reality was created and implemented, such that the shooting team could see low-resolution version of the final assets and could trigger the long clips of animation on command. So, it was important for the assets to be worked on before the stage of shooting, with the details added and refined only after the scenes were shot. Those were done by MPC, working on the master scenes in London, whilst developing an “asset management system” such that the scenes could be translated into something that was compatible with Unity, the game engine.
With the use of HTC Vive headsets Jon Favreau, Caleb Deschanel and Robert Legato with other important crew members could submerge into the virtual world being able to explore it like a real set. Within the virtual world they had access to a lot of settings, such as the lighting, placement of sun, choice of sky (out of 350), position of the camera, variety of lenses.

The team would make suggestions ‘based on what they thought it was going to look like when they filmed it’, be it changing the way an animal is walking, or position of assets in the shot. Despite the expensive side of virtual reality equipment, the ability to pre-determine such key characteristics which make-up a big part of the movie all in the virtual reality meant that it would require less crew and equipment, the choice and application would be instantaneous and hence more convenient infrastructure-wise. This way it brings more flexibility to the set. But one has to still have a great sense artistically and visually wise to be able to use all the various instruments to their advantage.
MPC lead lighting artist, Samuel Maniscalco, would have to light the world according to several factors, such as time of the day, location of the scene, placement within the larger story. The lighting was determined in the Unity such that it was possible to know the direction is was falling and how it would affect the drama when it was finalised. However, the downside of the VR production is that it was only possible to see how properly it was lit later after the scene was shot. Thus, it is important for the filmmaker to understand the process in advance. Having someone as part of the filming crew who knows how to use the visual tools straightaway and be able to adjust lighting, colour and editing on the spot is a big must, as that way they could show the director immediately of what they are intending to do. Thus by the time that the film was being shot, a big digital file would be created, which would contain the performance of the characters and the settings in 360 degrees, with all the dialogue and songs pre-recorded and synced with the characters in the virtual world. The only left thing to do was to record with the virtual camera and apply the virtual lighting.


The actual shooting of the movie was held in a 25-foot-square area called the Volume. Despite it being physically restrictive, due to technological involvement, they could update the scale of their movement in regard to the scene, for example, moving a meter in real life would translate as moving two or four inside the virtual world. Using a camera or something that would represent the camera, Favreau and his crew would physically move it around the stage. The three-dimensional flight path was tracked and reflected inside the virtual world, thus enabling the team to ‘shoot’ inside Unity. Having a custom setup where it was combining the Vive with OptiTrack sensor system and US Digital encoders, the crew could use and track the conventional camera equipment, be it Steadicam stabilisers, cranes and wheeled dollies. Furthermore, those filmmaking tools could be repurposed for other uses, such as a coded pan or tilt on a dolly or head, tilt up thus lifting the camera up in the air like the arm of a Fisher dolly. A drone pilot was hired to operate a virtual quadcopter such that aerial shots could be captured in a believable manner. One of the difficulties that arises with the Virtual Reality toolset is how to make the film appear having a human touch to it, having to understand how to imitate the conventional filming if the movie was shot in real life. One of such examples was the requirement of the drone for a wide aerial shot of Zazu. Following the pre-set put virtual path an operator with great experience of drone-like movement in real life, would know how to move it, such that it felt natural for the audience eyes.
Use of the Virtual Production implied that the animation inside the master scenes were always repeatable and identical, meaning the filming crew could shoot the action as many times as they needed to. This also got rid of the need to use multiple cameras, allowing for the operator to focus on a single camera. After the shoot, the so-called “3D scene files” would get sent to MPC, where in their turn, they would translate the camerawork into a version of the movie that had final production quality, assests and animation. This was a very new workflow for the company, but it had its advantages, such as eliminating the need to track the camera as it was done already. However, this sort of production increased the amount of work done by the VFX company, as MPC did all the visual effects: animation, compositing, lighting.

Overall, “Lion King” brought new technological step and advancement in the world of cinematography. Whilst being on a more expensive side, the use of Virtual Reality has some impressive applications and brings the ability to use countless instruments, all accessible via one headset and pair of tools for the hands. Being both the advantage as well as a disadvantage it reduces the necessity for a big crew during the stage of shooting but would probably require more people from the side of post-production as well as pre-production. Nowadays, more projects are bringing the virtual reality to the production appearing more and more convenient and available for other projects.
