Glassworks has been nominated for a TV BAFTA Award for its VFX work on the critically acclaimed Black Mirror ‘Bandersnatch’. The film contained 250 visual effects shots and as sole VFX vendor, Glassworks worked in close collaboration with director David Slade and the team at House of Tomorrow to deliver the dark immersive vision for this game-changing Netflix interactive episode.
Duncan Malcolm, VFX supervisor at Glassworks says: “Glassworks was involved in the very early R&D stages of the Bandersnatch project, helping to create ideas for the viewers interactive choice points. Collaborating with the production team at House of Tomorrow at the very beginning meant that we really became engaged with the project as it developed from script to final film. Since scenes were shot several times with various outcomes that could be explored multiple times during one viewing, careful consideration was taken for all aspects of continuity. For the story to flow seamlessly across the variations of timelines, the scripting and production planning had to be executed with great precision. With the episode containing over 250 visual effects shots, some of the bigger VFX sequences which were contained within their own story timeline brought some exciting challenges."
“The mirror sequences were shot with 3 x Arri 65 cameras which were synced together and the footage was then used to build Stephan's 3D reflection emerging from the mirror. The bathroom film set was actually two identical rooms, one in reverse with removable walls and was created to look like the 80s and then redressed for the 70s. The VFX requirements on this section on the shoot schedule were quite significant and so the Glassworks VFX team had to be confident of the technique used and very quick to react to changes.The shoot timescale was tight, but due to the detailed planning and testing, ended up being a great success. Once the footage arrived at Glassworks the detailed construction work on the CG reflections began."
“Throughout the film, director David Slade wanted to stay true to the various eras portrayed, so the scenes based in the 70s were captured on 35mm film, the news footage was shot on 16mm and the Game Review studio coverage was shot on old PAL Tube cameras. The VFX had to also be crafted to stay true to the period so visual effects were heavily leaned on to match cathode-ray tube screens with PAL content embedded into scenes which were then brought together with the real televisions captured in camera.
“The iconic Trellick Tower was undergoing renovation at the time of filming which brought its own challenges since the efficiency of the builders meant the scaffolding almost climbed higher than the floor where filming was taking place. Luckily not quite. It did mean that wherever the Trellick Tower exteriors could be seen, the bottom 23 floors had to be recreated in post. Capturing various passes with a drone camera gave us a good start with the construction of the CGI build. We then used a bespoke tool to populate the busy balconies with bikes, washing and random domestic clutter. The top of the building would have remained untouched in post, if it weren’t for all those post 80’s satellite dishes needing to be removed!”
Glassworks MD Aleks Ugarow adds; “Glassworks has been involved in the VFX on a number of seasons of Netflix Black Mirror and to now be part of the team nominated for a BAFTA for the critically acclaimed ‘Bandersnatch’ makes us all feel really, very proud.”
