Following the events of the first film, Enola Holmes 2 follows Enola on her quest to unravel the disappearance of a missing girl, assisted by her close associates and her older brother, Sherlock. Spin VFX and The Yard VFX worked together to provide the majority of the visual effects for the film, with around 550 VFX shots required overall. “Working directly with the movie VFX supervisor, we had to deliver photorealistic period images and scenery, staying true to the spirit and tone of Enola Holmes as laid out in the first installment,” says Edward Taylor, VFX Supervisor for Spin VFX on the film.

“The conversation started with Helen Judd, Mike Ellis and myself around two years ago,” remarks Laurens Ehrmann, Senior VFX Supervisor and Founder of  The Yard VFX. “They asked me if The Yard would like to work on Enola Holmes 2. Of course, it was a great opportunity for us,” Ehrmann explains. “They showed me some concept art and explained the project, and we started from there. In the same period, I had some conversations with Aymeric Auté, and I proposed he join us for the show. Then we started sharing our thoughts with Mike, regarding the different environments that we had to craft, especially the outside of the matchstick factory and this big aerial shot over the Thames, where the camera is flying over the dock to reach Enola in the street.”According to Ehrmann, there weren’t a lot of images for the time period. “We tried to build a bunch of references. The main references from Mike were Jack the Ripper and murky London with lots of pollution, as well as Peaky Blinders,” he says.

“There weren’t many pictures, as it was the end of the 19^th century and beginning of the 20^th century,” adds Auté, who served as VFX Supervisor. “We tried to go a little further in time, around 1930, as there are more pictures, but we had to take care as it was more industrial in this time period. We tried to get as many references as possible, and we created a mood board with Mike. They sent us what they wanted architecture-wise and details of windows, for example, to really fit with the time period.”

The Spin VFX team was meticulous when it came to the final details. “The harsh smoke-filled realities of Victorian England were present but moderately gentrified in order to create an accessible vision in which the story could be presented,” Taylor says. “Period correct was always on our minds as we scoured through Lost London: 1870-1945, London’s Lost Riverscape: A Photographic Panorama, as well as Spitalfieldslife.com, nationalarchives.gov.uk and numerous other websites. The devil was in the details much of the time, as any new photography is littered with television cables, security alarms and cameras, power boxes/junctions, etc. All of these had to be digitally removed in order to sell the turn of the [18th to 19th] century time frame.”

The Yard started with their own concepts for every shot “with a big mood board with lots of pictures we had gathered, just to give them our feelings and thoughts regarding the look of the shot,” Ehrmann details. “After that we spoke about how we would craft and build the shots. For example, for the aerial drone shot, the initial on-location plate over the river with the dock, we were supposed to keep the water as it is, but to ease the connection between our CG environment and the water, we decided to recreate everything, including the water. With the CG water we were able to manage the connection with the wooden docks, to add this kind of morning smoke over the water. We were asked to connect the street with the water with a drain, but an inclined plane, where the water is flowing over the bricks. So, the idea to recreate everything was a good one, as it gave us the ability to connect everything. We added a few extras, which were shot onstage in front of greenscreen, just to add people to the background. A lot of simulation for all of the smoke coming out of the chimneys.”

Overall, The Yard created 63 shots for the film, notes Luhrmann, “18 outside matchstick factory and 45 shots inside the matchstick factory. They shot a room, which we duplicated in depth. Sebastien Fauchère, Comp Supervisor, created a setup to recreate this second room and to be able to craft every shot really fast. We didn’t have to go to the CG render, everything was inside Nuke. It was pretty fast to develop on every shot.”

The establishing shot proved to be particularly challenging for The Yard to create. “It was a really big environment,” Auté says. “Because it’s a drone shot, we can’t do this on matte painting. We have to really build it in 3D to manage all the parallax to recreate the mood of old London with this kind of move. We started from really wide, and we have to go to almost close-up inside the streets, with the water on the grounds. It was the most challenging in terms of 3D.”

“We started from wider and then went close to the actress, meaning that every single aspect needed to be really defined. We did have time to craft it because the project’s duration was nearly six months. Six months for 63 shots is a lot of time to develop and build all of the assets and do the layouts. It was challenging but not exhausting,” adds Ehrmann.

The trickiest locations to capture for Spin VFX were usually dealing with cameras that were traversing the area. As Taylor explains, “The theatre stage interior and the rooftops and their scope, blending CG with practical, were generally the most challenging. The cameras and created geometry have to be in complete sync to achieve the desired illusion, not to mention lighting and any fluid dynamic elements such as water and smoke. Trying to make seamless transitions for such large and varied vistas was truly a challenge.”

In terms of the most difficult effect to realize, Taylor notes that, “As happens from time to time, creating invisible effects can be perceived as simple, but can often be challenging. The carriage explosion was exceedingly tricky, being nestled in the branches of trees, and blending practical elements alongside CG, as well as the various panoramas of London from a hillside and out a window.”

“For the whole project, we had to almost set up in parallel, as a lot of shots were inside the factory and they were more 2D centric,” Auté says. “We also had a few shots where we had to build specific assets, such as cranes or the docks building. We started to build these assets in 3D, but at the same time create the layout to place the camera and see where we need to add detail and what we can render in 2D. When we had all this established, we started to refine the texture of the lighting. Or, in some cases we only did matte painting to extend a street. We tried to spread the work between the 3D and 2D team to have everything go together at the end. They have a kind of ownership of the shots, and sometimes it is good to have someone work on one piece. It’s creating a kind of energy, and people are more involved.”

Concludes Taylor, “Our VFX Producer, Brandy Drew [with Spin VFX], created an environment where daily conversations with artists kept collaboration moving forward and information flowing, no question too small, no concern to go unrecognized. Organized by level of difficulty and availability of resources, the plan was created and the workload balanced. We delivered on time and on budget.”
