See? Not that awful. [dinosaur roars] [screaming]
Examine these images from the film “Jurassic World: Dominion”
Observe how the Giganotosaurus’ tongue moves when it opens its mouth and how its skin responds to its roar.
All of these reactions were captured on camera from this animatronic Giga puppet designed to resemble a real dinosaur.
The actual Giga measured 20 feet in height and 50 feet in width.
However, the puppet is missing the majority of its body. Building out the entire dinosaur would have rendered it immobile, so the practical and digital teams had to work together to create this.
The production crew had only three months to build the full head.
The head is the largest dinosaur ever seen in any of the “Jurassic” films, according to director John Nolan.
Therefore, the creature effects team began with a digital model based on the production designer’s ideas and sculpts. The head of the Giga was then printed and carved from polystyrene.
David Vickery: Even though we only created the head from the top of the nose to just above the shoulders, we needed to know what the entire monster resembled before we could begin creating the animatronic.
This allowed them to synchronize the CGI and real versions from the beginning and prevent drastic design modifications during post-production. John utilized this head to create a more camera-ready puppet. First, oil-based clay was used to prevent drying and cracking.
John: We skimmed the entire document, similar to decorating a cake.
Twenty sculptors were required to give the Giga its rough skin texture, drawing inspiration from historical data and crocodiles.
The skull was then encased in a fiberglass mold to maintain its integrity while John injected foam latex into it.
To cure the skin, the foam needed to be baked in the mold, but John’s oven was too small to accommodate the head. Instead of completing this stage in one piece, it is divided into seven smaller bits and baked in two separate ovens.
The final pieces of foam were then adhered together.
There was still a chance that the foam pieces would separate during filming, therefore each component was additionally protected by netting.
The last layer of foam latex was necessary for flexibility and served as a convincing substitute for the Giga’s rough, opaque shell.
But the Giga also required physical characteristics that responded realistically to light while being filmed, and foam latex lacked the required translucency for times like as this, in which the Giga opens its mouth widely.
When the tongue is raised, you want a small amount of light to pass through the tip.
Instead of foam latex, the tongue and rear of the creature’s throat were created entirely of silicone. A small amount of light still needed to penetrate through its outer skin and scales, but too much silicone would have weighed down the puppet. Thus, these characteristics were concealed while painting the creature’s skin ivory green.
John: On top of the skin, the translucency and details must be faked using an airbrush.
Observing the Giga under two different lighting conditions reveals that its skin color varies. But making this puppet appear lifelike was a another matter. Additionally, it had to move realistically. John and David chose, based on the knowledge of paleontologists, to match the mechanical skeleton within the head to what a true Giganotosaurus might look like.
David: We were creating a metal skeleton for the interior of the dinosaur in an effort to make its movement as believable and realistic as possible.
Servo motors were then employed to power the head, according to the report. By installing rotating servos in the appropriate anatomical locations, the head could rotate, pivot, and roll.
These pivot points aligned precisely with the vertebrae of the dinosaur, as well, according to David.
The facial movements of the animatronic were very important when engaging with the cast. The team had to link these servos to simultaneously move multiple pieces.
When Bryce Dallas Howard stuns the Giga, the servos controlling the eyeball and eyelid are preprogrammed as a single action.
John: With this control system, we only needed to click a single button because we understood how the system should respond. We desired that place to be as natural as possible. Then we developed eye sockets that could move left and right, so the entire eye socket, including the lids, could move left and right, and each time it blinked, the eyes would actually retract. There are some reptiles and birds that do this.
As the Giga roars toward Chris Pratt, it is also possible to observe all of these moves.
John: The eye could retract and blink, and the nictitating membrane would also move across to shield the eye.
The heavier sections of the head, like as the tongue and neck, could not be supported adequately by servos alone. Because they were manufactured from silicone, they weighed more.
John: The tongue is likely of surfboard proportions.
Therefore, these servos were combined with hydraulics to move the extra skin. And for more perilous interactions, such as when the Giga uses its mouth to drag Bryce Dallas Howard, a team of fifteen puppeteers controlled the movements live on site.
The group also incorporated safety precautions. Hydraulics used to operate the Giga’s jaws prevented its mouth from closing completely if someone went too close, and preprogrammed controls kept the performers safe.
If something exceeded a particular threshold, the puppet would immediately shut down.
These procedures were equally vital for the safety of the puppet, as stated by the narrator. Due to its modular construction, the animatronic was quite unstable. This made some action-packed moments more appropriate for CGI, such as this shot of the Giga smashing its head through a massive window.
David: It was about to break, or it was about to rip the skin.
For that moment, the scene employs both a computer-generated head and a window break. John’s Giga head was scanned in 3D to generate the CG appearance. But these pictures returned to the Giga puppet traveling through a fixed window that had already been broken.
Run!
A similar combination of CG and practical effects was required here, as stated by the narrator. The damage of the catwalk is real, but the dinosaur is not. However, the pragmatic mind returns in this shot.
Due to the flawless transitions between CG and practical, the general movements of the dinosaur had to match the digital model precisely, despite the fact that just the head was practical.
According to David, they addressed with this issue in the 2018 film “Jurassic World: Fallen Kingdom.”
The manner in which the animatronic was moving did not let us to add the remainder of the body. They were unfit.
The special effects crew then constructed this unique rig and attached the 2-ton head on it. The mechanical equipment was also digitally incorporated within the CG body of the Giga. There is an obvious distinction between the actual build and the animated body.
Wherever the dinosaur went, the mechanical apparatus would also move. Therefore, we knew that the mechanical apparatus had the precise range of motion to place the dinosaur in the correct location.
They were able to seamlessly transition from a view of the animatronic to a fully CG counterpart, with the transition being absolutely undetectable, due to the hard effort that went into integrating practical and CG effects.
We intended to use it on set to generate genuine tension and passion, as well as a connection between our performers, director, and cinematographer.
You choose a language. The dinosaur is portrayed using the puppeteers on the set. It provides our animators with a language to work with and within.
