The art of writing stories for animated cartoon films

By Robert Grock

Crafting stories for animated cartoons demands a delicate balance of creativity, structure, and audience awareness. Unlike live-action storytelling, animation offers boundless possibilities. Characters can defy gravity, worlds can shift in an instant, and a talking toaster can steal the show.

Yet, this freedom comes with responsibility. A compelling cartoon story must resonate emotionally, deliver clear themes, and keep viewers glued to the screen, whether they’re kids, adults, or both. The process is both an art and a science, requiring writers to blend imagination with discipline.

At the heart of any great animated story is a strong concept. Consider Pixar’s Up. The premise was off the wall. A widowed balloon salesman floating his house to South America with thousands of balloons. It sounds absurd on paper. But its emotional core, a man grappling with loss and rediscovering purpose, grounds the fantastical in universal truth.

Writers begin by asking, “What’s the hook?” The hook isn’t just a quirky idea; it’s a promise to the audience of what’s at stake. For Up, it’s adventure tethered to heartbreak. A good hook grabs attention and sets the tone, whether it’s the chaotic family dynamics of The Simpsons or the surreal absurdity of Adventure Time.

Once the concept is set, character development takes center stage. Cartoons thrive on memorable characters, often exaggerated yet relatable. Take SpongeBob SquarePants. He’s a sea sponge with an infectious laugh and relentless optimism, but he has his flaws. He’s hopelessly naive, occasionally selfish Sound familiar? They make him human.

Writers must define what drives their characters. What do they want? What stands in their way? In Inside Out, Riley’s emotions (Joy, Sadness, Anger) are characters with distinct personalities, each serving the story’s exploration of growing up. Strong characters carry the narrative, turning even simple plots into emotional journeys.

World-building is another cornerstone. Animation allows creators to construct realities unbound by physics or budgets. The key is consistency. In Avatar: The Last Airbender, the world of benders and elemental magic feels alive because its rules are clear. Firebenders draw power from the sun, waterbenders from the moon. Writers must establish these rules early and stick to them.

A poorly-defined world confuses viewers, while a vivid one, like the vibrant underwater city of Bikini Bottom, immerses them. Every detail, from the landscape to the culture, should serve the story.

Plotting an animated story requires economy. Cartoons, especially for younger audiences, often run 11 or 22 minutes per episode. There’s no room for fluff. Phineas and Ferb masters this, packing each episode with a dual storyline — stepbrothers building wild inventions and their sister trying to bust them — all while weaving in a villainous subplot with Perry the Platypus.

The structure is tight, with setups and payoffs timed to perfection. Writers often use classic storytelling frameworks, like the three-act structure, but adapt them for brevity. Conflict drives the plot, whether it’s external (a villain) or internal (a character’s doubt).

Humor is the secret sauce of many cartoons, but it’s tricky to nail.

Great cartoon humor lands with both kids and adults, often on different levels. The Simpsons excels here, blending slapstick (Homer’s antics) with sharp cultural satire. Writers layer jokes, such as visual gags for kids and witty dialogue for grown-ups. In Gravity Falls, a monster chase might end with a goofy pratfall, but the dialogue sneaks in clever references to conspiracy theories. Timing is critical; a punchline must hit fast. Test screenings often reveal what lands and what flops, refining the comedic rhythm.

Emotional resonance elevates a cartoon from forgettable to timeless. Toy Story isn’t just about toys coming to life; it’s about friendship, loyalty, and fear of being replaced, or becoming obsolete. Writers tap into universal emotions to connect with viewers. This requires subtlety.

In Bluey, an Australian series about a dog family, simple games like “Keepy Uppy” (keeping a balloon aloft) become profound meditations on parenting and childhood. Writers must avoid heavy-handed moralizing; kids can smell a lecture a mile away. Are your kids like that? Instead, they show, don’t tell, letting characters’ actions reveal the heart of the story.

Collaboration shapes the process. Writers work with animators, voice actors, and directors to bring the story to life. In Spider-Man: Into the Spider-Verse, the script’s bold narrative, multiple Spider-People across dimensions, demanded innovative animation styles to match.

Writers must anticipate how their words translate visually. A single line, like Shrek’s “Ogres are like onions,” sparks a visual montage that deepens the character. Storyboards and animatics (rough animated drafts) help writers see if the pacing and tone work before full production begins.

The audience matters immensely. Writing for preschoolers, as in Bluey, means simple language and clear morals, but with enough charm to keep parents engaged. Shows like Rick and Morty, aimed at adults, present complex themes and dark humor. Writers study their demographic, often drawing from personal experiences or observing real kids and families.

Phineas and Ferb creators Dan Povenmire and Jeff “Swampy” Marsh pulled from their own childhoods, infusing the show with authentic sibling dynamics. Knowing the audience ensures the story hits its mark.

Revision is relentless. A script might go through dozens of drafts. Feedback from networks, test audiences, or even social media (X posts often reveal fan reactions) shapes the final product. Adventure Time evolved from a quirky short to a sprawling epic because creators listened to what resonated. Writers must stay flexible, cutting beloved scenes if they don’t serve the story. Ego has no place here; the story comes first.

Finally, a great cartoon story leaves room for imagination. Looney Tunes thrives to this day because its simple premises, Wile E. Coyote chasing Road Runner, spark endless variations. And other applications. Automaker Plymouth licensed the Road Runner image and meep-meep horn for a line of its performance cars in the late ‘60s.

Writers plant seeds for future episodes or deeper lore, keeping fans hooked. The best stories linger, whether through a catchy theme song or a character’s heartfelt goodbye. Crafting animated stories is about capturing hearts in a few vibrant frames, blending whimsy with truth, and creating worlds where anything is possible, yet everything feels real.
