The Digital and Practical Effects of Sinners

Ryan Coogler’s Sinners is a work of love–a multilayered story that encapsulates heritage, music, and the supernatural. A movie that feels authentic and grounded–an incredible effort that not only pushed the boundaries of filmmaking, it corralled all departments to create something that was owned and shared by every single artist. This collaboration is evident by the unprecedented blend of visual and practical effects. Representing both departments are VFX supervisor Michael Ralla, VFX producer James Alexander, SFX makeup designer Mike Fontaine, and SFX coordinator Donnie Dean who revealed how practical rooting and digital expansion melded into something that is almost invisible and most definitely believable.

Michael Ralla called the VFX of Sinners timeless. It was very important that their work was counterintuitively unnoticed–serving the story instead of gearing towards spectacle. “The visual effects in this movie support the filmmaking–integrated seamlessly with the [IMAX] celluloid look. The look of the film transports the audience into that world of 1932 Mississippi … It has a feel of a bygone era. Everything that we created had to honor whatever was in front of the lens,” James Alexander said. Ralla added that the baseline of the VFX effort in Sinners was to have a practical base for every single shot to preserve the creative intent.

Depression-era Mississippi

The period transformation of current day Louisiana into Depression-era Mississippi was more than historical accuracy. Especially during the driving sequences, the fields of sugar cane were transformed into endless rows of cotton, which were “emotionally very important to Ryan. He wanted to get this sense of isolation that he’s seen in Mississippi, which conveys a feeling of no escape. There’s nowhere to hide, nowhere to run, and nobody who can help you,” Ralla shared. The director’s first encounter with cotton fields was during a production trip for Wakanda Forever with the VFX supervisor–an incredibly powerful moment that instantly connected him to his ancestry.

Arguably the biggest period VFX scene was the train station, which involved massive digital set extensions and relied on production designer Hannah Beachler’s detailed feedback: “We went through many rounds of iterations until she was happy with the digital section of the train station that we built, which is quite frankly most of the image because we didn’t have a train,” Ralla said. To achieve historical accuracy, the VFX team spent time doing proper research for other elements in the scene, particularly the cars which Alexander explained could only be black Model T Fords which were full digital vehicles–all this under the scrutiny of the IMAX large format. On the other hand, the main street of Clarksdale where we first meet the Chow family was an example of invisible VFX work, shot on location on Railroad Avenue, Donaldsonville which was dressed by Beachler on street level and then cleaned up of any technological advancements (electricity cables, AC units, etc.) by Ralla’s team. “That’s how we ended up with more than 1000 shots instead of what was supposed to be, less than 200,” he revealed.

The Twinning

Twinning as a visual effect goes back almost to the dawn of cinema. As technology evolved, the illusion of seeing identical faces within a frame became something so credible that it is no longer a mere fascination. For Sinners, the VFX team examined the evolution of this special effect–from the basic split screen to motion control to present day cutting edge digital tools–experimenting each approach six weeks before principal photography. However, Ryan Coogler’s ambitious vision and most importantly Michael B. Jordan’s critical eye pushed Ralla and Alexander to go beyond the traditional “hockey mask” and camera overs for Smoke and Stack and instead embraced full head replacement. “All of the twinning work is fundamentally grounded in Michael B. Jordan’s performance. No twinning shot could be a success without his performance,” emphasized James Alexander.

The “footprint in the snow” shot, as he calls it–a reference to The Empire Strikes Back’s Battle of Hoth scene where the AT-AT and AT-ST walkers make contact in the snow, a pinnacle in VFX history that sold the interaction to the audience–was the introduction of the twin brothers as they exchange a cigarette. “In this particular instance, we chose the route of shooting him, getting photographic plates and combining those with compositing. It was particularly time consuming because we had lots of sync points to hit. There’s the sync of the dialogue, there’s the sync of the spatial placement of the hands as the cigarette gets passed back and forth. We knew that the audience would believe in the story from that point onwards,” Alexander explained. To capture every nuance of Jordan’s performance, Ralla shared that the team filmed the actor twice with a technodolly, doing several “takes until Ryan was happy with the performance for the A side, then another seven takes to just nail the timing and get a B side that works well with all the handovers–all that in 110 degree heat in Louisiana. We had a very narrow window until it would all start to fall apart.” The subtlety that Michael B. Jordan constructed for both characters started to surface as Ralla and team were bringing the scene together in editorial and post–understanding the different mannerisms that distinguish one brother from the other.

The VFX team didn’t stop there. Sinners is full of action, and to truly capture and preserve Michael B. Jordan’s micro performance without disrupting his acting rhythm, they engineered the Halo Rig–a 360 degree shoulder harness with cameras all around (manufactured by Wild Rabbit) to capture every possible angle for a full head replacement. The portability of the Halo Rig allowed the Sinners VFX artists to record the actor’s performance on set, in the right lighting on location, and in the moment of the scene–the latter being a key factor in facilitating the best possible results: “We could fly the Halo Rig in, put it on Michael B. Jordan’s shoulders, and capture while the whole production was moving around us, which was amazing. He would be able to stay in the moment and perform immediately after being one of the twins as the other twin and keep all of that momentum,” Alexander explained. “We were always trying to break any obvious pattern to a point where Ryan, on day 30, got a little frustrated … ‘We’ve never done a twinning shot the same way as what we’ve done before. Why is it always different?’ And I was like, ‘It’s going to be hard to explain, but it’s so that there’s no recognizable pattern. I know it’s frustrating right now, but you’ll thank me later!’ That was a big thing, and it’s part of the theme of the film–embracing imperfections and breaking regularity so that you can basically never tell what the split line is … you can never tell if it’s digital or practical,” Ralla added.

The Vampires

At the center of the plot, there are the vampires. Sinners defined new lore for the creatures of the night, bringing an animalistic nature to the way they consume (and turn) their victims while still maintaining a persuasive personality. Although the period aspect of Sinners doesn’t affect the vampire design specifically, Mike Fontaine and team took it into consideration in order to tap into its realism: “This isn’t a fantasy world, this is very much a real world, and it has to be believable. But at the same time, there’s this undercurrent of supernatural energy that gets revealed throughout the film. The vampires, to me, always felt ancient, that the spiritual aspect to this is something that’s been around a lot longer than in the 1930s. We went to nature and started looking at anything we could find as opposed to other vampire films or even art. We were looking at predatory animals and the wounds that they inflict.” He added, “We were looking at different fangs and teeth in certain animals. I wanted the fangs to kind of curl backwards, almost like a hook … if you got bit by one of these creatures it would actually hook you in. That became another technically difficult problem to solve–to make it so that they can speak and that it’s not going to cut their mouths. We ended up making these very thin, delicate veneers. It was really about finding technical solutions so that we could make all of this stuff actually work on set practically.”

One of the most fascinating details of the vampire makeup in Sinners is the tapetum lucidum effect. The contact lenses (created by the incredibly talented Cristina Patterson) was the first indicator that these folks are not what they seem. While the effect was fully practical, in certain instances where the lenses limited the actors’ performance, a faithful digital recreation was done by the VFX team–so accurate that even Fontaine admitted he could not tell the difference on screen. “There’s a moment outside the juke when Remmick comes up to all the heroes who are gathered at the door, and it looks like his eyes turn on. The way the light catches them, they’re very subtle at the beginning, and they kind of flare up in the middle of the shot … that’s all in camera. It’s the nature of how the light interacts with those practical lenses, and it’s something that we would never have done were it only a digital creation, because it’s intentional, it’s part of storytelling. That subtlety was only possible because we filmed it for real.” James Alexander then added that “later on when we did recreate the contact lens effects, and the instance that I’m thinking of is when Bo comes to the door and his eyes do illuminate, we were able to have an accidental but perfect reference from the real contact lenses that Mike supplied. It’s that imperfection and irregularity and real world subtlety that is almost impossible to create from scratch and is only possible because everything is based in reality.”

Remmick’s Introduction

Remmick’s introduction is built on deception, and the burns on his body play a big part in that reveal. “He’s always pretending to be something that he’s not–a guy on the run who has been injured, or this musician that just wants to join a party–he’s never being totally forthcoming. To me, I always see makeup as a means to create disguises,” Fontaine explained. “These burns are actually the result of him being in the sun as a vampire, and so they’re generated in a supernatural way, but his story is something else–his story is that he’s under attack, and the characters feel sympathetic enough towards him that they actually bring him into their house. Understanding that the burns were created in a supernatural way, we still wanted to make them feel as realistic as possible, so we dove into a very disturbing research period where we were looking at burn victims and what happens to their skin. We ended up finding some amazing medical photographs to have the most believable interpretation of it. We actually printed these photos of real burns as temporary tattoos that we could map out and put all over [Jack O’Connell’s] body as our base, then we used prosthetics on top of that and airbrushed.” To emphasize his deceitful act, the SFX team applied dentures to make Remmick’s jaw swollen along with a swollen eyepiece–all of this in tandem with costume designer Ruth Carter who created a look that would show the burns through the fabric holes. And to give the audience the first clue to the supernatural nature of the character, Michael Ralla and James Alexander’s team came in to make the burns sizzle–which again had a practical reference from Fontaine’s makeup team.

The Montage

The montage has a very different visual language from the rest of the film. Both VFX and SFX played a crucial role in bringing to life IMAX’s longest scene to date. Ralla explained, “We stitched it together from several passes that we shot independently … it all had to be in sync with the music and the choreography. Any time we went over one of those stitch points (for instance, the CG piano), that was our takeover point from section one to section two. Then there’s another one where we’re going past the beam, which is a little bit more traditional, but all of that had to happen at the exact same time. It was a colossal planning effort.” As the musical experience reaches its peak, the roof literally sets on fire–carefully executed by Donnie Dean’s team then digitally recreated by the VFX department. “It started out being a small panel, like 6 x 6, and then over time it came out that this thing needed to be the full size of the roof in the real juke joint. The panels got so big we actually had a forklift holding them because it was so massive. We’re using IMAX cameras at high speed, so you only had a minute and a half of footage–we had to have the whole roof burn away in that amount of time. We found different materials that would burn at the right speed while also giving you the right look so that it burns away and no pieces fall down. It was a team of three guys that did nothing but work on that for a couple of months. We also had to come up with a way to protect the cameras because there’s only four of those in the world, and we had two underneath that roof while it’s on fire. We came up with an air system to protect the cameras that basically blew a blade of air across the lenses, and anything that would fall down into the lens, it would blow it away before it got to the camera. Then Ryan wanted to be in the room with it too, which made things even more interesting,” Dean said. Then Coogler wanted to elevate the moment by going through the roof–all the way up to the ancestors. “At that point we had filmed the static elements, so we needed to replicate all of that in CG so that we could push the camera through. What you see in the film is a full CG roof with a full CG fire and everything. Eventually, our IMAX plate became a reference, but the shot would have never looked the way it looks without that reference,” Ralla shared.

Remmick’s Demise

As the sun rises, the vampire nightmare comes to an end in the most supernatural way. Sammie slams Remmick with his guitar, and the result is an incredibly iconic makeup. “The idea of the resonator of the guitar getting embedded in Remmick’s head and then him ripping it out was all Ryan. At that point we had to figure out the most realistic way to depict that. We collaborated with Donnie on making that resonator because it was too heavy to actually put in his head, so we came up with the idea of it being like one of the old gags where you have the machete with the whole piece cut out of it and it goes in … the first time seeing that was in Tom Savini’s Grande Illusions when I was a kid, from the movie Maniac.” Mike Fontaine added, “There was a conversation with Donnie on making this lightweight resonator and then a conversation with Michael and James about if he pulls this thing out of his head, can we then digitally fill in the sphere where there’s a piece missing? They were able to do it seamlessly. You can’t tell no matter where that begins and ends. Then my team had to figure out how to get this fiberglass disk that’s painted chrome on his skull that can then be removed, so we created a fiberglass plate that went on Jack O’Connell’s head that had magnets in it, hidden by prosthetics and a wig. He could perform in it and then grab it and actually pull it off of his head and then reset it.” The side of Remmick’s face reveals his true self underneath his skin showcasing a demonic grin–pushing the makeup literality into something purely supernatural.

His demise is what you would expect in a vampire, instant combustion by sunrise, but with a literal spin. As the evil spirit leaves Remmick’s body, a fire vortex manifests in a spectacular way. The effect was a momentous effort by Donnie Dean’s team: “By the time we figured out how to make it turn and spin, they’re like, ‘Well, it needs to be in the water.’ We wound up getting custom electronics and plumbing that had swivels on it, and we force-fed propane into it out of several 100-pound tanks and then used a vacuum machine for cleaning parking lots. We plumbed it into a turbine that we built by hand, which was probably 5 ft in diameter. It had blades, so there’s air being shoved into it. There’s the heat and water resistant electronics that’s all run remotely, and it’s all spinning with several bottles of propane plumbed into it. In a water tank! We wanted to do it on location, but there were a lot of things about that location that became less than ideal … it was a miserable place to be. So we wound up taking a portable tank from our shop and modifying everything so that we could put this whole contraption into it on a soundstage.” The practical effect ended up 60 ft in the air, to the top of the stage, which was an invaluable reference for the VFX team to bring it all together.

The Ring

The end credits scene in Sinners was the cherry on top in terms of collaboration–containing an invisible VFX edit that changed an important characterization detail. The ring worn by Stack “initially said ‘Smoke’, but people were super confused in a lot of the test screens … Stack wanted to honor his brother. So we changed it to ‘Stack’. We never built a Stack ring. There wasn’t one in existence, so [Ruth Carter] texted me a sketch with a ring design that we then implemented. I don’t think anyone would ever identify it as a VFX shot. It’s a fairly simple one overall, but I think that’s a good story to tell because again, it’s just collaboration. That was one of the last things that we did in the last three weeks of post. Ruth helped us make this seamless … it’s her design that really makes it stand out, why no one ever questioned it,” Ralla shared.

With more than 1000 VFX shots and outstanding practical effects, Sinners is an incredible achievement that needs to be discovered and celebrated. These behind-the-scenes stories are proof that when great minds come together in a true spirit of collaboration, anything is possible in storytelling.
