Find the Original Stories
Every Disney film in Once Upon a Source started somewhere else. Here are the original books, poems, plays, and fairy tales — ready to read for yourself.
As an Amazon Associate I earn from qualifying purchases.Each chapter of Once Upon a Source covers one Disney animated film and the original source material it was adapted from. Some of those originals are short enough to read in an hour. Some are novels you’ll be glad you finally got around to. All of them are different — usually darker, often stranger, sometimes more beautiful — than what you saw on screen.
The list below is organized by chapter. Every link goes directly to an edition on Amazon. If you buy through one of these links, I earn a small commission at no cost to you — it helps support the book and future projects.
Volume One — The Classics
Snow White and the Seven Dwarfs (1937)
Original source: “Snow White” (Schneewittchen) · Brothers Grimm · First published 1812
The dwarfs have no names in the original. Snow White wakes not from a kiss but when her coffin is jostled and a piece of poisoned apple dislodges from her throat. The Evil Queen’s punishment is dancing in red-hot iron shoes. Disney invented the names, the kiss, and the ending.
Pinocchio (1940)
Original source: The Adventures of Pinocchio · Carlo Collodi · First published 1883
Pinocchio kills the talking cricket — the character who became Jiminy — with a hammer on page two. He is hanged at one point. The boys who go to Pleasure Island don’t turn back. Disney softened nearly all of it. The original is worth reading.
The Adventures of Ichabod and Mr. Toad (1949)
Two source works: “The Legend of Sleepy Hollow” — Washington Irving, 1820 · & The Wind in the Willows — Kenneth Grahame, 1908
Ichabod Crane’s fate in Irving’s original is genuinely ambiguous — he simply vanishes, and the Headless Horseman may or may not be Brom Bones in a costume. Grahame’s Wind in the Willows, meanwhile, is a quiet, lyrical book about friendship and slow river life — Mr. Toad’s motorcar mania is one of its smallest subplots.
Cinderella (1950)
Original source: “Cendrillon” · Charles Perrault, 1697 (also “Aschenputtel” · Brothers Grimm, 1812)
The glass slipper, the fairy godmother, and the pumpkin carriage all come from Perrault’s French version. In the Grimm version, the stepsisters cut off parts of their own feet to force the slipper to fit, and birds peck out their eyes at the wedding.
Volume Two — The Golden Age
Peter Pan (1953)
Original source: Peter and Wendy · J.M. Barrie · First published 1911
In Barrie’s original, Peter returns for Wendy years later and has completely forgotten her. He takes her daughter instead. Then her granddaughter. He never changes. He never remembers. The flight over London is real. The rest is sadder than it looks.
Sleeping Beauty (1959)
Original source: “La Belle au bois dormant” · Charles Perrault, 1697 (also “Dornröschen” · Brothers Grimm, 1812)
Perrault’s story doesn’t end when she wakes up — that’s only the halfway point. The second half involves the prince’s mother, an ogress who secretly tries to eat the children, and a pit of vipers. Disney stops at the kiss. Perrault kept going.
The Little Mermaid (1989)
Original source: “Den lille Havfrue” · Hans Christian Andersen · First published 1837
Andersen’s mermaid doesn’t get the prince. She turns into sea foam. He wrote it after a man he loved deeply married someone else. Disney gave her the wedding the original story never had.
Beauty and the Beast (1991)
Original source: “La Belle et la Bête” · Gabrielle-Suzanne de Villeneuve, 1740 / Jeanne-Marie Leprince de Beaumont, 1756
There is no Gaston in either original story. The real villains are Beauty’s own jealous sisters. Lumière, Cogsworth, and Mrs. Potts don’t exist — Disney invented every one of them for the 1991 film.
Volume Three — Myth and Legend
The Hunchback of Notre Dame (1996)
Original source: Notre-Dame de Paris · Victor Hugo · First published 1831
Hugo wrote this novel to shame France into restoring the cathedral. It worked — restoration began almost immediately after publication. The cathedral survived the 2019 fire. Hugo has been dead since 1885. His argument is still winning.
Hercules (1997)
Original source: The Heracles Mythological Tradition · Greek classical sources
In the oldest versions, Heracles — driven mad by the goddess Hera — kills his own children. His Twelve Labors are a penance for that act. Disney turned this into a story about a teenager trying to fit in.
Treasure Planet (2002)
Original source: Treasure Island · Robert Louis Stevenson · First published 1883
Stevenson wrote the book while bedridden with hemorrhaging lungs, at a rate of a chapter per day. He drew the original treasure map with his stepson on a rainy afternoon. The map came first — the book was written to explain it. The original map was later lost.
Frozen (2013)
Original source: “Snedronningen” (The Snow Queen) · Hans Christian Andersen · First published 1844
This is the longest fairy tale Andersen ever wrote — seven chapters structured almost like a novel. Elsa and Anna don’t exist in it. The hero is a girl named Gerda who travels alone across a frozen landscape to rescue her friend. She succeeds. She gets no musical number.
Volume Four — Animals and Adventures
Bambi (1942)
Original source: Bambi, a Life in the Woods · Felix Salten · First published 1923
This is not really a children’s book. It is a meditation on mortality, predation, and what it means to live as prey in a world controlled by forces you cannot see. The Nazis banned it and burned it. Salten fled. Disney’s film kept the tragedy and softened nearly everything around it.
Alice in Wonderland (1951)
Original source: Alice’s Adventures in Wonderland · Lewis Carroll · First published 1865
Carroll was a mathematics lecturer at Oxford. The nonsense follows precise logical rules. The Queen of Hearts threatens execution constantly and never once follows through — Carroll was making a point about the emptiness of authority. The real Alice was seven years old when he told her the story on a boat trip in the summer of 1862.
The Sword in the Stone (1963)
Original source: The Once and Future King · T.H. White, 1938 (based on Le Morte d’Arthur · Sir Thomas Malory, 1485)
Merlin’s animal transformations in White’s original are deliberate lessons about different forms of power. A fish, a hawk, an ant, a goose, a badger — each teaches Arthur something specific. Disney kept the transformations. The lessons didn’t make the cut.
The Jungle Book (1967)
Original source: The Jungle Book · Rudyard Kipling · First published 1894
In Kipling’s original, Mowgli is eventually rejected by the human village and returns to the jungle permanently. Disney gave him a cheerful send-off with a musical number. Kipling wrote a serious, melancholy story about belonging to two worlds and fitting entirely in neither.
Volume Five — The Renaissance
The Lion King (1994)
Original source: Hamlet · William Shakespeare · c. 1600–1601
The Lion King follows Hamlet closely enough that you could use the film as a study guide for the play. The murdered father, the usurping uncle, the prince in exile — it’s all there. The difference: in Shakespeare’s version, almost everyone dies. Simba gets a happier ending than Hamlet.
Mulan (1998)
Original source: The Ballad of Hua Mulan · Anonymous · c. 400–500 CE
The entire original source is thirty-one lines of Classical Chinese poetry. There is no dragon, no comic relief, and no romantic subplot. Disney expanded thirty-one lines into an eighty-eight-minute film.
Tangled (2010)
Original source: “Rapunzel” · Brothers Grimm · First published 1812
In the original, Rapunzel is in the tower because her father made a deal with a witch before she was born. The prince wanders blind through the wilderness for years before finding her again — not seconds. Flynn Rider doesn’t exist in the Grimm story. Neither does the Snuggly Duckling.
Aladdin (1992)
Original source: “Aladdin and the Wonderful Lamp” · Attributed to Hanna Diyab · First published by Galland, 1710
No Arabic manuscript of Aladdin’s story has ever been found. The story may have been invented in Paris in 1709 by a Syrian storyteller named Hanna Diyab. Nobody knew his name until 2021.
Volume Six — The Final Collection
Mary Poppins (1964)
Original source: Mary Poppins · P.L. Travers · First published 1934
Travers held Disney off for twenty years before selling the rights. She wept at the premiere — not from joy — and spent the rest of her life objecting to what had been done to her character. Mary Poppins appears when she wants to. So does the east wind.
The Black Cauldron (1985)
Original source: The Chronicles of Prydain · Lloyd Alexander, 1964–1968 (based on The Mabinogion · Medieval Welsh mythology, c. 1350)
The film based on these books nearly ended Disney’s animation studio — The Care Bears Movie outgrossed it opening weekend. The books have never gone out of print. Lloyd Alexander built the world of Prydain from Welsh mythology he first encountered while stationed there during World War II.
Oliver & Company (1988)
Original source: Oliver Twist · Charles Dickens · First published 1837–1839
Dickens worked in a factory at age twelve when his father was imprisoned for debt — a fact he hid from almost everyone for most of his adult life. Oliver Twist was partly his testimony about what that felt like. Disney reimagined it with dogs in 1980s New York.
Tarzan (1999)
Original source: Tarzan of the Apes · Edgar Rice Burroughs · First published 1912
Burroughs invented Tarzan and all of Africa that surrounds him at a borrowed desk in a Chicago pencil-sharpener company, having never visited the continent. He failed at nearly everything else he tried, then became one of the most commercially successful popular fiction writers of his era. A city in California is named after his fictional character. He’s buried there.
