Directed by Lana Wachowski, this long-awaited next chapter in the groundbreaking franchise reunites some of the original Matrix cast, as well as welcomes some new faces. Keanu Reeves and Carrie-Anne Moss reprise their roles as Neo and Trinity, taking on a new world of challenges in the search for truth and freedom from the reality simulation.
Culminating in a climactic third-act action sequence that takes in a high-octane motorbike chase, hurtling human torpedoes and a death-defying helicopter stand-off, Framestore’s team was tasked with honoring the style of the first three films, while bringing fantastic new VFX elements to the table in a cohesive blend of live action stunts and seamless CG artistry.
“The third act of the film typically hosts the biggest action sequences as the plot reaches its finale,” says VFX Supervisor Graham Page. Framestore’s talented artists pulled out every trick – from digital doubles, stunts, and environment work – no VFX stone was left unturned to provide a film as visually impactful as the original trilogy.
Although initially offered 204 shots, Framestore’s London team ultimately delivered 443 shots for the film. “There’s a legacy with The Matrix
that got people really excited, they’re iconic sci-fi/action films, and everyone wants to say they’ve worked on one – to the point where a lot of artists volunteered to work on a single shot, just to be able to say they’d worked on a
film,” explains Page.
Revisiting Classic Effects
“There was a heavy weight of expectation to build on and improve the VFX of the previous entries in the franchise, known for their groundbreaking digital effects,” says Page. In some cases, Framestore used modern techniques to reference and rebuild effects from the original films, such as Neo’s famous shield power, first seen in The Matrix Reloaded.
The transformation of Jonathan Groff’s Agent Smith is reminiscent of the earlier films featuring Hugo Weaving. “2D morphing effects were revisited using modern 3D morphing of digital characters with hair and cloth,” explains Page. “In general, the feel of the film was less stylized and more organic and realistic than the originals, meaning more detail was required in models, and work was all carried out at 4k.”
Leaps and Swarms
The Matrix trilogy was known for its dramatic stunt work, and so for this latest incarnation, the stakes were already high. The loyal fan base has grown to expect high-octane action with visually stunning stunts. “The pressure was on,” agrees Page, “VFX has come a long way since the original
Matrix in 1999, and the fans know this, so the bar for the big action sequences was set very high.”
In the third act of the film, a swarm of people chase Neo and Trinity as they speed through the streets of San Francisco on a motorcycle. This climactic sequence required the addition of a crowd of up to 100 digital characters into hundreds of shots. Framestore created fully digital humans with simulated clothing, hair and facial animation, as well as digital doubles for Neo and Trinity for the motorcycle sections that were too dangerous to capture in-camera. “The talented Matrix team tried to do as many stunts as possible in person,” says Page, “but the swarm sequence in particular was too dangerous, and so we supplemented with VFX to blend with the shot footage and create an action-packed final shot.”
“For safety reasons, they hadn't been able to film extras near any vehicles or the camera, so we knew our extras would be front and center, and the movement had to be consistent with the extras they had already filmed,” adds Animation Supervisor Max Solomon.
“We started out by analyzing the sequence and creating a detailed list of the actions we were going to need – some were generic, but many were shot-specific. We found four stunt actors of varying sizes and set up the Framestore motion-capture rigs in the largest space in our London studio. We spent two days working through the list of actions, capturing every kind of variation we could think of, throwing ourselves around like kids at soft play! It was a lot of fun.”
After the motion capture, the animation team had to examine every frame of the reference footage and make their selects for cleanup. “We spent about two months with a team of six animators creating a library of performances with classic names like AgitatedBystanders001, ShotOnRoofOfCar002 and MenacingWalk003, tidying up ground contacts, fixing joint chain pops, adding hand and finger animation, fixing scale and intersection issues,” says Solomon. “A lot of the performances were captured with all four stunt actors together, so that we could get interactions and more complex integrated movement. Meanwhile, we painted an animatic of the sequence using stills in Photoshop, showing where and how many digital extras would be added to each shot.”
Some of the stunts were too dangerous for even motion capture, as the final shots of the swarm sequence called for people in the high-rise buildings of San Francisco to hurl themselves down at Neo and Trinity. “We started out using cutting-edge physics simulation techniques to match the impacts with the ground,” says Solomon. “By varying trajectory and dive pose, we could get different kinds of impacts. With our extensive library of clips, blocking the shots was very quick, but we found that a lot of actions didn't work ‘off the peg,’ so we started creating bespoke shot-specific animations, often shooting new reference footage ourselves, to ground the actions in reality.”
A key part of the approach to the sequences was the combination of practical filmmaking with digital effects. Real explosions were enhanced with digital debris and the CG crowd was intermingled with real-world extras and stunt performers. “The work had to be integrated into and matched to real-world photography with smoke, atmosphere, lens flares, practical debris, and fire,” continues Page. “Fortunately, it was shot pre-COVID, so Director Lana Wachowski had time during the first lockdown to edit the big action sequence before production picked back up again.”
“Neo and Trinity's final leap of faith from the 44 Montgomery building in San Francisco, as seen in the trailer, was carried out as an incredible stunt by the actors, and digital intervention was used sparingly and with care,” says Page. “Keanu Reeves and Carrie Anne Moss did the jump for real several times over the course of a few days. Framestore then matched the footage together, removed the wires, and stabilized any motion from the rig, cutting between a real and CG helicopter. We also replicated the Montgomery building in order to destroy it later in the scene.”
In total, Framestore built 26 unique digital characters, 18 vehicles, helicopters, and a cat, along with various environments. Complex effects simulations were completed for crushing cars, destruction, and helicopters exploding and crashing into buildings.
The Matrix Resurrections was produced by Warner Bros. Pictures, in association with Village Roadshow Pictures and Venus Castina Productions.
