Darrel Bowen: Production Model Designer, The Simpsons

Darrel Bowen has shaped the visual backbone of The Simpsons for almost twenty years, defining the production models that keep every character, prop, and object consistent across the series. His work runs through The Simpsons Movie, the Disney+ shorts, the Universal Studios ride, and earlier eras of Animaniacs, Pinky and the Brain, Darkwing Duck, X-Men, and Scooby-Doo. We talked about the invisible rules that decide whether a design belongs in a world or quietly breaks it the moment it appears.

When you build a character or prop for a world as familiar as The Simpsons, what’s the invisible decision that decides whether it belongs there or feels off?

For me, the invisible decision always comes down to line attitude and silhouette logic. If the line weight, curve rhythm, and overall simplicity don’t feel like Springfield DNA, the design instantly reads as foreign, even if the audience can’t articulate why.

In The Simpsons universe, everything has a built-in looseness, but it also has a very distinct look that can’t be separated from its identity and has to be followed precisely. Curves beat angles, practical shapes beat ornate ones, and the silhouette has to read in under half a second. That internal compass — “Would this exist in Springfield without calling attention to itself” — is what silently determines whether a design truly belongs.

In long-running shows, visual rules accumulate quietly. Which unspoken rule guides most of your choices, even if the audience never learns it exists?

The big one is: Don’t design anything that looks like it knows it’s funny. The humor in The Simpsons comes from the writing, the characters, the staging, the acting, and the timing, not from overly stylized or “performing” props. Props and backgrounds have a poker-face quality. They play the straight man to the joke.

So the unspoken rule is: Make the object honest. The writers define the humor; the design shouldn’t compete with it. If the gag needs support, I simplify the design so the joke lands through contrast, not decoration. The audience never knows this rule exists, but the artists and the writers rely on it constantly.

Every design has a point where you remove something instead of adding it. What do you cut that viewers will never notice but artists always feel?

I cut the second idea every single time. Designers naturally fall in love with clever add-ons — extra seams, decals, folds, little personality flourishes — but on The Simpsons the second idea is almost always what breaks the style. On other shows I’ve worked on, like Scooby-Doo, Animaniacs, Pinky and the Brain, and Darkwing Duck, the visuals often get enhanced in storyboards before the design stage. The Simpsons is the opposite. Clarity comes first because the gag has to read instantly.

So what I remove is the flourish only another artist or the writers or production would ever notice: an extra angle, a fancy fold, a “cool” detail that muddies clarity. Viewers never know what vanished, but artists and writers feel the cleaner read. It’s the difference between a design you can animate and a design that only works in a portfolio.

You’ve worked across studios with very different visual languages. What’s the early signal that a design choice is going to break the internal logic of a world?

The earliest signal is a rhythm mismatch. Every studio’s style has a rhythm — Disney is lyrical, WB is punchy, The Simpsons is conversational and geometric, anime might be mechanical or elegant. If a new design interrupts that rhythm, even slightly, it’s already breaking the world’s logic.

Examples: too much anatomical structure in a Simpsons character, too much texture in a WB design, too much realism in a Disney face, too much angular exaggeration in a grounded world. When the flow stutters, the world quietly rejects the design. That’s my cue to recalibrate.

In your own process, what’s the smallest adjustment that changes everything about a character’s read, even though no one could point to what changed?

Eye spacing and small facial-gesture adjustments. Every time. A millimeter inward or outward can shift a character from confident to worried, from charming to vacant, from on model to not quite right. It’s microscopic, but it changes the entire emotional read.

Additionally, gesture posing makes a massive difference. A tiny adjustment in posture or attitude can suddenly clarify a character’s quirks, personality, or branding. It’s subtle, but it’s often the difference between a character feeling alive versus just drawn.

When Darrel talks about design, he isn’t talking about making things look good. He’s talking about the unseen structure that decides a world’s reality. For him, the invisible decisions are the ones that actually define it.
