10 Unseen Depths: The Radical Concept Art That Defined—And Almost Drowned—Finding Nemo

Contents
The visual development of Finding Nemo represents one of Pixar’s most ambitious artistic and technical leaps, a journey from simple sketches to a fully realized underwater world. This process, spearheaded by Production Designer Ralph Eggleston, was a masterclass in using traditional art—specifically vibrant pastel illustrations—to define the look of a groundbreaking computer-generated film. As of late 2025, the enduring legacy of this concept art continues to be celebrated, revealing the deep artistic foundations and numerous creative detours that ultimately shaped the beloved 2003 classic. The film’s final aesthetic, a blend of hyper-realism and cartoon expressiveness, was meticulously planned in the concept phase, with artists tackling the unprecedented challenge of rendering water, light, and a massive coral reef ecosystem. While the final movie is a masterpiece, the early concept art and rejected ideas offer a fascinating glimpse into a version of the film that was often darker, sometimes creepier, and structurally very different from the story we know.

The Core Creative Team and Visual Biography

The success of Finding Nemo’s visual language is inseparable from the core team of artists and directors who spent years translating the deep blue sea into a digital canvas. Their combined vision established the film’s distinctive look, blending the organic beauty of the ocean with the stylized charm of Pixar’s characters.

  • Director: Andrew Stanton
  • Co-Director: Lee Unkrich
  • Production Designer: Ralph Eggleston (1965–2022)
  • Character Art Director: Ricky Nierva
  • Visual Development Artists: Dan Lee, Mark Whiting, Bill Robinson
  • Studio: Pixar Animation Studios
  • Original Release Date: May 30, 2003
  • Thematic Focus: The concept art was driven by the need to capture the feeling of being underwater, emphasizing volumetric lighting and subsurface scattering.
  • Key Artistic Technique: Ralph Eggleston famously used vibrant pastels to create the mood and color scripts, which served as the emotional and visual blueprint for the entire film.

The Radical Evolution of Character Designs and Rejected Concepts

The journey from initial sketch to final character model is rarely linear, and the visual development for Finding Nemo was filled with numerous iterations and discarded concepts. These early designs reveal significant shifts in character tone, plot, and the overall atmosphere of the film, highlighting the meticulous process of visual storytelling.

1. The Pastel Palette: Defining the Underwater Mood

Before any complex CG water simulation could be rendered, Production Designer Ralph Eggleston established the entire film’s visual blueprint using simple, vibrant pastel illustrations. This technique was crucial for defining the mood and color script for every scene, from the saturated warmth of the Coral Reef to the murky, terrifying depths of the abyss. Eggleston's pastel work provided a quick, tactile way to convey the feeling of light filtering through water—a phenomenon known as volumetric lighting—which became a technical hallmark of the film.

This traditional medium allowed the team to experiment rapidly with color theory. For instance, the concept art for the dentist’s office in Sydney Harbor often used stark, sterile whites and blues to contrast sharply with the lush, warm colors of the ocean, visually reinforcing the idea of a hostile, unnatural environment where Nemo was trapped.

2. Bruce the Shark’s Terrifying Early Designs

One of the most dramatic shifts occurred with the character of Bruce, the great white shark. The final film portrays Bruce as a friendly, if slightly manic, member of a "Fish-Friendly Sharks" support group. However, early concept art was significantly more menacing and "oddly terrifying."

Initial sketches leaned heavily into the classic horror tropes of sharks, depicting a more monstrous, less anthropomorphic creature. The concept art explored a version of Bruce that was genuinely scary, a constant threat rather than a comedic character struggling with his nature. This darker design was eventually softened to align with the film's core theme of a father overcoming his fears, making Bruce's struggle for vegetarianism a source of comedy rather than pure terror.

3. Dory’s Design: The Challenge of Expressiveness

While Nemo’s design, created by Character Designer Dan Lee, was reportedly "discovered quickly" and changed very little, Dory presented a unique challenge. Blue tangs are not naturally the most expressive fish. The concept artists, including Character Art Director Ricky Nierva, had to find a way to give Dory a wide range of emotions without losing the recognizable form of the fish.

The solution found in the concept art was to exaggerate her eyes and mouth, giving her a perpetually optimistic, slightly scatterbrained look. Early sketches show a range of blue hues and fin shapes, but the final design settled on a simple, round, and instantly endearing form to perfectly match Ellen DeGeneres’s energetic performance.

4. The Rejected Plot: Marlin's Darker Journey

The concept art and storyboards often reflect abandoned plot points. One of the "rejected ideas" involved a significantly darker journey for Marlin. In an early version, Marlin was even more of a control freak, and his fear was an overwhelming, almost crippling force. Some concepts explored a more intense psychological breakdown for Marlin as he traveled, including interactions with characters that were meant to represent his warped mind or desire to forget his tragedy. The final film streamlined this emotional arc, keeping the focus on the physical journey and the bond with Dory, but the concept art confirms that a much bleaker narrative was considered.

The Technical and Artistic Hurdles Solved by Concept Art

Finding Nemo was a monumental technical undertaking for Pixar. The concept art was not just about aesthetics; it was a crucial tool for solving complex CG problems. The artists had to visually define what a digital ocean should look like before the technical crew could build the tools to render it.

5. Mastering the Illusion of Water and Light

The single biggest technical challenge was the CG water simulation. The concept artists had to intensely analyze real-world footage of the ocean to understand how light behaves underwater. This process involved studying:

  • Caustics: The patterns of light and shadow created on the seafloor by the rippling surface of the water.
  • Subsurface Scattering: How light penetrates the fish’s skin and scatters before exiting, giving them a soft, translucent, and organic look.
  • Fog and Murkiness: The concept art for the deeper, less-explored parts of the ocean used a heavy atmospheric perspective (or "fog") to convey depth and mystery, a visual cue that the technical team then had to reproduce digitally.

Ralph Eggleston’s pastel paintings were instrumental here, offering a visual target for the technical artists to aim for, ensuring the final rendering captured the aesthetic of a hand-painted masterpiece rather than a cold, sterile computer model.

6. The Look of the Tank Gang

The Tank Gang—Gill, Peach, Bloat, Gurgle, Deb, Bubbles, and Jacques—required a distinct visual style to separate them from the wild ocean fish. The concept art for these characters emphasized their worn, slightly damaged nature, reflecting their long confinement in the dentist's aquarium. Gill, in particular, was given a scarred, rugged look, a visual metaphor for his status as the hardened leader and escape artist. The contrast between the pristine, vibrant ocean concept art and the duller, more confined space of the tank was intentional, using color and texture to heighten the sense of imprisonment.

7. The Role of Squirt in Early Storyboards

While Squirt, Crush's son, is a fan-favorite supporting character, early concept art and storyboards suggest he had a much larger, more integrated role in the film's plot. One piece of art showed Nemo and Squirt actively avoiding Bruce the shark together, implying a more extended partnership or even a subplot where the two young fish navigated a danger zone. This indicates that the story’s structure was fluid, and the concept phase explored various pairings and adventures before settling on the final, streamlined narrative.

Topical Authority: The Enduring Legacy of Visual Development

The concept art for Finding Nemo remains a cornerstone of Pixar’s visual development history. It demonstrated that even in the face of immense technical challenges—like simulating an entire ocean—the foundation of a great animated film must be rooted in strong, traditional artistic principles. The work of Ralph Eggleston and the visual development team provided the essential color, mood, and emotional context, effectively creating an artistic "bible" for the CG animators. The concept art’s legacy is in its ability to bridge the gap between traditional illustration and cutting-edge technology. It proved that a simple pastel sketch could communicate the complex light refraction of the ocean more effectively than any early digital test. This dedication to visual storytelling, from the earliest sketches of a terrifying Bruce to the final, warm glow of the Coral Reef, is what cemented Finding Nemo not just as a technical marvel, but as an enduring piece of art. The unseen designs and rejected ideas are a testament to the rigorous, iterative, and often surprising creative process that goes into making a timeless classic.
