She’s messy. She’s pink. She’s absolutely terrifying if you’re a bird.
When people talk about Disney villains, they usually default to Maleficent’s cold elegance or Ursula’s drag-queen-inspired theatricality. But if you grew up watching the 1963 classic The Sword in the Stone, the witch in The Sword in the Stone—better known as Madam Mim—probably occupies a very specific, chaotic corner of your brain. She wasn't trying to take over a kingdom. She didn't have a tragic backstory involving a lost inheritance or a snubbed invitation. Mim just wanted to kill a child because she thought it would be funny.
That’s dark. Honestly, it’s much darker than most of the "complex" villains we see in modern cinema.
Madam Mim represents a specific era of Disney animation where the stakes felt weirdly personal. Directed by Wolfgang Reitherman, the film was the last one released before Walt Disney’s death. It has this loose, sketchy art style that fits Mim perfectly. She’s all jagged edges and frantic energy. While Merlin is the quintessential man of science and logic (despite being a wizard), Mim is pure, unadulterated id. She’s the antithesis of everything Arthur is supposed to learn.
The Wizard Duel: A Masterclass in Character Design
The highlight of the entire movie—and arguably one of the best sequences in animation history—is the Wizard’s Duel. This is where the witch in The Sword in the Stone really shines. If you haven't watched it recently, the scene is basically a high-stakes game of Rock Paper Scissors, but with biological warfare.
It starts because Arthur, transformed into a sparrow, accidentally falls down her chimney. Mim is delighted. Not because she likes guests, but because she loves "ugly" things and finds the idea of snuffing out a life inherently joyful.
When Merlin arrives to rescue his pupil, the rules are set. No disappearing. No non-magical weapons. Only animal transformations.
What makes this scene legendary isn't just the magic; it's the personality. Merlin transforms into things that are smart. He becomes a turtle to endure, a rabbit to escape, a caterpillar to hide. He plays defense. Mim? She plays dirty. She turns into a giant purple dragon, breaking her own rule about "no disappearing" by vanishing and reappearing to ambush him.
She’s a cheater. And that’s why she’s a perfect foil.

The animation by the legendary "Nine Old Men," specifically Frank Thomas and Ollie Johnston, gives Mim a weight and a "squash and stretch" quality that makes her feel alive. When she turns into a cat, she’s not just a cat; she’s a Mim-cat. She keeps that shock of white hair and that bulbous nose. You can always see the witch inside the beast. It’s a level of visual continuity that modern CGI often struggles to replicate with the same soul.
Why the Witch in The Sword in the Stone Matters Today
We live in an age of "sympathetic villains." Everyone needs a reason to be bad. Cruella needed a dead mom; the Joker needed a "bad day."
Madam Mim doesn't need a reason. She’s just mean.
There’s something incredibly refreshing about that. In the context of T.H. White’s source material, The Once and Future King, the characters are often symbols of different philosophies. Mim represents the "might makes right" mentality. She believes that because she is powerful, she has the right to be cruel.
Interestingly, the Disney version of the witch in The Sword in the Stone is significantly different from the book version. In White’s novel, she’s more of a traditional, seductive enchantress who traps the boys. Disney turned her into a troll-like figure who hates sunshine. It was a brilliant move. By making her physically "ugly" by her own standards (and beautiful by ours when she tries to be "pretty"), the filmmakers created a character who lives entirely outside of societal norms.
She’s an anarchist. She’s the chaos that Arthur will eventually have to keep at bay when he becomes King of the Britons.
The Science of the Fever
The way Merlin finally defeats her is through biological science, which is a wild ending for a fantasy movie. He doesn't turn into a bigger dragon. He doesn't use a death spell.
He turns into a germ. Specifically, Malignalitaloptereosis.

It’s a fake disease, sure, but the logic is sound. He attacks her from the inside. He uses his brain to defeat her brawn. For a kid watching in the 60s—or a kid watching on Disney+ today—the message is clear: being the biggest dragon in the room doesn't mean you’ve won.
Mim ends up in bed, covered in spots, shivering, and absolutely miserable. It’s a humiliating defeat for a character who prides herself on being the "Magnificent Madam Mim."
Behind the Voice: Martha Wentworth
You can’t talk about the witch in The Sword in the Stone without talking about Martha Wentworth. She voiced Mim with a raspy, manic energy that sounds like she’s perpetually on the verge of a coughing fit.
Wentworth was a radio veteran, known as the "Actress of a Hundred Voices." She brought a level of improvisational feel to the lines. When she says, "I can be beautiful, lovely and fair! Silly girl with the flaxen hair!" the transition from a screech to a melodic lilt is flawless.
It’s the kind of voice acting that defines a character. Without that specific vocal performance, Mim might have just been a generic hag. Instead, she’s an icon of the "eccentric villain" trope.
Why We Keep Coming Back to the Sword in the Stone
The movie itself is often overshadowed by Cinderella or The Lion King. It’s a smaller story. It’s episodic. It feels more like a series of lessons than a grand epic.
But that’s its strength.
The encounter with the witch in The Sword in the Stone is the final exam for Arthur. It’s the moment where he sees that the world isn't just full of fish and squirrels; it’s full of people who will hurt you because they can.

Merlin’s victory isn't just about saving Arthur’s life. It’s about proving that knowledge and education are the only real defenses against tyranny.
If you’re looking to revisit this classic, don’t just watch it for the nostalgia. Watch the way the colors shift when Mim enters the room. Notice how the background art becomes more frantic. Pay attention to the sound design—the way her magic sounds "wet" and "crunchy" compared to Merlin’s "sparkly" bells.
Actionable Insights for Fans and Collectors
If you're a fan of the film or the character, there are a few things you should know about her footprint in the Disney universe today.
- Visit the Parks: Madam Mim is a rare character, but she does appear in parades, particularly during the Halloween season at Disneyland and Walt Disney World. She’s often part of the "Frightfully Fun Parade."
- Check the Villainous Board Game: If you're into tabletop gaming, Mim is a featured character in the "Disney Villainous" expansion Bigger and Badder. Her gameplay mechanics perfectly mirror the Wizard Duel, requiring players to transform into different forms to defeat Merlin.
- Read the Source Material: Pick up The Once and Future King by T.H. White. Seeing how Disney adapted a fairly minor, dark character into a comedic powerhouse is a great lesson in storytelling and adaptation.
- Art Study: For aspiring animators, the Wizard Duel is a "must-copy" sequence. Try sketching the transition frames between Mim as a crocodile and Mim as a tiger. The "in-betweening" work there is some of the best ever produced by Disney.
Madam Mim might not have a castle or an army of goons, but she has something better. She has personality. She’s a reminder that sometimes, the most dangerous thing in the world is just a person with a lot of power and a very bored mind.
The witch in The Sword in the Stone remains a masterclass in how to build a villain who is simultaneously hilarious and genuinely unsettling. She doesn't want your soul. She doesn't want your kingdom. She just wants to play a game. And she usually makes sure the house wins.
Next time you're scrolling through a streaming service, skip the new releases for an hour. Go back to 1963. Watch a pink-haired witch try to eat a sparrow. It’s a lot more educational than you remember.
To really appreciate the craft, look for the "making of" segments on Disney+ that highlight the work of the Nine Old Men. Understanding the physical labor that went into every frame of Mim’s transformation adds a whole new layer of respect for the character. You can also find high-quality lithographs of the duel on secondary markets like eBay, which are staples for serious Disney animation collectors. Focus on finding cels that show the "purple dragon" phase, as those are the most sought-after by enthusiasts.
Finally, if you’re introducing the film to a younger generation, point out the "rules" of the duel. It’s a great way to talk about fair play and how logic can overcome brute force—even when the opponent is literally a dragon.
