The first step in the process was to establish how Rob Marshall envisioned mermaids moving underwater. Animation tests were commissioned during the pre-production phase, where a grayscale mermaid was created without specific designs.

Animation supervisors Pablo Grillo and Ferran Domenech with Tim Burke worked together to develop animations that captured the director’s desired aesthetic.

Marshall, known for his background in musical theater and choreography, provided clear and specific feedback on the movements, ensuring that the mermaids’ performances aligned with his vision.

Shooting Methodology

Once the desired movements were established, the team determined the filming and technical aspects of the shoot. It became apparent that most of the mermaid characters would need to be animated due to the physical restrictions of the actors being held in rigs.

However, the team aimed to capture the actors’ faces during filming to maintain live-action performances. Special effects supervisor Steve Warner was tasked with designing rigs that allowed maximum freedom of movement for the actors on set while being manually operated.

To prepare for the shoot, Rob Marshall utilized his unique rehearsal process, working with a small group of dancers and choreographers to block out scenes, particularly the musical numbers.

Basic scene blocking was captured on camera using a Sony a7, which provided material for editor Wyatt Smith to work with. The rehearsal process helped Marshall and the team visualize each scene’s timing and overall feel.

Now, let’s learn about how they create the movements of the mermaid body!

Re-Thinking Rigs

One of the challenges in the underwater filming process was ensuring that the actors had control over their movements and were not merely being manipulated by the rigs.

The team designed different rigs that allowed the actors, especially Halle Bailey, to lead the performance. The rigs had multiple axes of rotation and were manually pushed around on stage.

Puppeteers assisted with the physical movements, picking up the actor from the hips while Halle created underwater movement in her upper body, leading actions with her head and arms. This approach resulted in a fluid and natural flow of movement.

The team conducted several weeks of rig rehearsals, allowing actors to adjust if a rig didn’t facilitate their desired movements. Some shots were captured as live-action, while others were done digitally using CG characters.

The extensive preparation ensured that Rob Marshall could focus on directing the emotional performances of the actors during the shoot.

How Much of the Body to Keep

To achieve the desired mermaid appearance, only the actors’ faces and hands were used for the live-action footage of the underwater sequences. Each shot was body tracked and animated, with everything from the clavicle down being rendered using computer graphics.

Additionally, digital hair was added to every actor to enhance realism. Long shots often utilized multiple live-action takes, seamlessly transitioning between live-action and CG characters to cover transitional periods.

To overcome the challenges of underwater hair movement, the production team employed cutting-edge techniques to create realistic and visually appealing hair for the mermaid characters. The process involved a combination of simulation and hand animation to achieve the desired effect.

Underwater Hair Simulation

The first step was to gather reference material. Underwater footage was captured using high-speed cameras to study the hair’s natural movement in the water. This reference material was invaluable in understanding the physics and dynamics of hair underwater, which served as a basis for computer-generated hair simulations.

A team of animators and hair specialists worked closely to develop digital hair for the mermaid characters. They started by creating a detailed 3D model of each character’s hair, taking into account its length, texture, and style.

The hair was then simulated using specialized software that accurately replicated the behavior of hair in the water.

The simulation involved applying physical forces to the digital hair strands, such as drag, buoyancy, and gravity. These forces were carefully calibrated to match the reference material and ensure realistic movement.

The simulation also focused on the surrounding water environment, including water currents and turbulence, to add further authenticity to the hair motion.

Hand Animation and Fine-tuning

While the simulation provided a solid foundation, the team recognized the importance of artistic control and fine-tuning. Hand animation refined the hair movement, adding subtle details and correcting discrepancies arising during the simulation process.

It allowed the animators to strike a balance between realism and aesthetics, ensuring that the hair complemented the characters’ performances and enhanced the overall visual appeal.

Besides, the digital hair was integrated with the live-action footage during the compositing stage. The compositors carefully matched the lighting, color, and CG hair’s shading with the live-action elements, seamlessly blending the two.

This integration was crucial in creating a cohesive and believable underwater environment, where the actors’ faces and expressions remained the focal point (while the hair added an extra layer of visual interest).

Bringing the Underwater World to Life

To bring the underwater world to life in The Little Mermaid, the production team faced the immense task of designing and constructing a visually captivating and believable environment.

The process involved two key aspects: designing the underwater scenery and implementing advanced visual effects.

Underwater Scenery Design

The first step in creating the underwater world was conceptualizing the look and feel. The production team collaborated with talented concept artists and designers to develop a unique and enchanting aesthetic for the underwater scenes.

They drew inspiration from various sources, including marine life, coral reefs, and fantastical elements to craft a visually stunning and cohesive environment.

Once the concept was established, the next phase involved translating the designs into physical sets and digital assets. For practical sets, intricate underwater sets were constructed, utilizing a combination of effects, props, and set extensions to give the illusion of an expansive underwater realm.

The attention to detail was crucial, with elements like colorful corals, swaying seaweed, and hidden treasures adding depth and realism to the underwater world.

Advanced Visual Effects Implementation

In addition to practical sets, advanced visual effects played a pivotal role in enhancing the underwater world.

The production team employed state-of-the-art techniques to seamlessly blend live-action footage with computer-generated imagery (CGI) and create a visually breathtaking underwater experience.

CGI was utilized to augment the practical sets and bring to life elements that were challenging or impossible to capture in-camera. This included intricate sea creatures, vibrant schools of fish, and mesmerizing underwater landscapes.

The visual effects artists meticulously crafted these digital assets, ensuring they seamlessly integrated with the live-action footage and adhered to the established visual style.

Moreover, the team utilized specialized techniques to simulate underwater environments’ unique lighting and color properties.

They replicated the play of sunlight filtering through the water, the diffused and muted color palette, and the atmospheric haze that gives underwater scenes their distinctive look. This attention to detail further heightened the realism and immersion of the underwater world.
