While much has been said about the stunning practical special effects of George Miller’s post-apocalyptic action film Mad Max: Fury Road, shot largely in South Africa and the Namibian desert, for visual effects supervisor Andrew Jackson, one of the best compliments is when people don’t even realize that what they are watching is, in fact, computer generated imagery.

In fact, for Jackson, the project spanned six years from preproduction to post. While Sydney-based visual effects house, Iloura, (formerly Method Studios), handled the vast majority of the film’s VFX work, Jackson had a team of about 15 people in the postproduction offices who handled over 400 shots. In total, the film has over 2,000 VFX shots out of 2,600.

“I was very much involved in shooting background plates and elements and a huge amount of still photography for environment enhancements,” said Jackson. “We got an enormous amount of material from the shoot to help in the post VFX.”

“A lot of what we did was augmenting what was already exciting live-action elements,” explained Jackson. That included a lot of environment extensions, as well as “some pretty major CG sequences as well.”

In particular, the film’s sand storm sequence was almost entirely a CG event, however Jackson explained that “My approach to visual effects is very much using live-action elements as much as possible. Even if it’s all CG, I always try to base it on some sort of element. So we shot the vehicles driving around for a base plate to work with. Occasionally, by the time you’re done, all of the elements in the shot have been replaced one by one, until there is nothing left of the original plate, but I still believe that the shots inherit something from the original plates that helps make them more believable. It may be only the camera move, but I feel that there is a benefit of basing a visual effects shot on some kind of a live-action plate.”

The film’s Citadel, the home base of the psychotic warlord Immortan Joe, is also entirely CG.

So we built that structure from real location, but transformed it to the shape we wanted.”

“We had to make them appear as if they’re moving,” he explained. “Sometimes it can be easy, when there isn’t much background, but there were some shots where the actors were standing on vehicles and climbing all over them, and we had to make them appear as if they were moving. When you a have a performance from an actor standing on a vehicle that’s not moving, to get that to appear as if they’re on a moving vehicle, without losing their performance was definitely one of the most challenging things in the film.”

Jackson explained that the film was shot on an ARRI Alexa, which has a native resolution of 2880, which gave them a little headroom to pan and zoom within the shots and still maintain a 2K image.

“George feels strongly about a technique he uses in editing to make the fast cut sequences flow smoothly, which is to focus on where the viewer’s eyes are at the end of one shot, and make sure that the subject is in that part of the frame in the next shot, so despite the speed of the action and the cutting, you never really get lost.”

“That process of lining up the subject does require blowing the shot up and re-framing it,” he added.

Another major CG environment was the canyon. “For the whole chase through the canyon, we did shoot in a canyon in South Africa, but there was hardly a shot there that was real,” said Jackson. “We made the canyon way taller than the actual location. To be honest most people had no idea that that work had been done. From a visual effects point of view, when people don’t know that they’re looking at VFX, that’s the ultimate compliment.”
