Have I gone mad? I'm afraid so. You're entirely bonkers. But I'll tell you a secret. All the best people are
Not Lewis Carroll — actually Linda Woolverton, for Disney’s 2010 filmLinda WoolvertonBorn 1952 · American screenwriter — screenplay, Alice in Wonderland (Walt Disney Pictures, 2010)
This is dialogue from Tim Burton’s Alice in Wonderland, released by Walt Disney Pictures in March 2010 from a screenplay by Linda Woolverton, and there are two errors in the popular version, not one. The words are not Carroll’s — “bonkers”, “gone mad” and “all the best people” appear nowhere in his books — and it is not a speech. It is a two-hander: the Hatter asks “Have I gone mad?”, and Alice gives the famous reply.
“Have I gone mad? I'm afraid so. You're entirely bonkers. But I'll tell you a secret. All the best people are” Not Lewis Carroll. Written by Linda Woolverton for Tim Burton's Alice in Wonderland (Walt Disney Pictures, 2010) — and the famous half is Alice's line, not the Hatter's. Traced by Quotle.info · Verbatim: “Hatter: Have I gone mad? Alice: I'm afraid so. You're entirely bonkers. But I'll tell you a secret. All the best people are.”

Alice in Wonderland (2010), as transcribed on Wikiquote
The popular version collapses the exchange onto one speaker and prints it as the Mad Hatter’s wisdom. In the film he only asks the question; the line everyone quotes is Alice reassuring him, with her hand on his forehead.
Wikiquote’s page for the 2010 film ↗ transcribes the exchange with its speakers intact — Hatter asking, Alice answering, stage direction and all — and its header credits the screenplay to Linda Woolverton, “loosely based on Lewis Carroll’s book”.
A site-wide insource: search of Wikiquote, which reads the raw wikitext of every page, returns exactly one page containing “You’re entirely bonkers”, and it is that film. “All the best people are” returns four pages, only one of them Alice-related — the same film. Neither phrase is on Carroll’s page ↗ or the Wonderland page ↗.
We downloaded the Project Gutenberg texts of ten of Carroll’s English books — 2.41 million characters — Alice’s Adventures in Wonderland ↗ (in two editions), Through the Looking-Glass ↗, The Hunting of the Snark, Phantasmagoria and Other Poems, Three Sunsets and Other Poems, Sylvie and Bruno, Sylvie and Bruno Concluded, A Tangled Tale, The Game of Logic and Symbolic Logic — flattened every line break so no phrase could hide across a line ending, and searched the lot. “bonkers”, “gone mad” and “all the best people” each occur zero times. There is no Victorian original here for the film to be quoting.
What Carroll did write about madness is in chapter six of Wonderland ↗, and it is an argument rather than a compliment. The Cheshire Cat tells Alice that a Hatter and a March Hare live nearby and “they’re both mad”; when she says she does not want to go among mad people, the Cat replies “Oh, you can’t help that… we’re all mad here. I’m mad. You’re mad”, and then sets out to prove it by comparing itself to a dog. The 2010 line is that idea turned into reassurance, which is a screenwriter’s move, not Carroll’s.
One thing we did not establish: whether Woolverton wrote the line from scratch or was reworking something older. We can show it is in her film and not in Carroll; we found no earlier appearance, but absence of a find is not proof of coinage, and we are not going to assert one.
In copyright. Screen writing is work for hire, so the rights in this dialogue sit with the studio rather than the screenwriter: the film was released by Walt Disney Pictures in 2010, well inside the term. Carroll’s own books are public domain, which is where the confusion costs something: a line credited to him reads as free to reprint, and this one is not.

The speakerThe Mad Hatter Speaker, not author
He asks “Have I gone mad?” and stops there. The transcription ↗ gives the whole of the famous reply — “I’m afraid so. You’re entirely bonkers…” — to Alice, with a stage direction about checking his temperature. Printing it as the Hatter’s self-description inverts the scene.

Why it is worth correctingThe Carroll credit Context
Carroll’s text and John Tenniel’s 1865 illustrations are out of copyright; this dialogue is not. So crediting the line to Carroll does more than misname its author — it quietly reclassifies protected 2010 screen writing as free-to-reprint Victorian text.
Given to the Hatter, the line is a madman’s boast — I am bonkers, and that is what makes me interesting. Given to Alice, which is how it was written, it is something much better: the sane character telling the frightened one that his madness does not disqualify him. Same words, opposite meaning, and the version on every mug is the weaker one.
It is also the tidiest example of how film dialogue becomes literature. The 2010 film adapts a public-domain book, so its new lines arrive wearing the old book’s clothes — and once a quotation site files it under Carroll, there is nothing in the sentence itself to say otherwise.
Given to the Hatter it is a boast. Written for Alice, it is kindness.
Read the full story
The 2010 film is not an adaptation of Wonderland so much as a sequel to it: Alice is nineteen and returning to a place she half-remembers. Almost none of its dialogue is Carroll’s, and Woolverton had a free hand with lines for characters readers think they already know — which is the ideal condition for a misattribution.
Carroll’s own madness scene sets the contrast. The Cheshire Cat does not comfort Alice about being mad; it informs her she is mad, declines to let her opt out, and then attempts a proof. The warmth in the 2010 line is entirely new, and warmth is what makes a quotation travel.

Born 1952 · American screenwriter, playwright & novelist · Beauty and the Beast, The Lion King, Alice in Wonderland, Maleficent
Linda Woolverton was the first woman to write an animated feature for Disney — Beauty and the Beast (1991), which became the first animated film nominated for Best Picture — and went on to co-write The Lion King and adapt her own screenplay into the Broadway musical. Her speciality is taking a familiar story and giving its heroine a spine, which is precisely what she did to Alice in 2010, and precisely why her dialogue gets mistaken for the Victorian source.
