The Book

24 Films. 25 Original Stories. One Book.

Every Disney animated film, paired with the fairy tale, myth, novel, or poem that inspired it — and exactly what changed along the way.

The Pitch

About the Book

Once Upon a Source is a 24-chapter journey through the stories behind the Disney films you already know. Each chapter takes one animated classic and sets it side by side with the book, fairy tale, myth, or poem that inspired it — walking through what stayed the same, what changed, and why.

It’s written for Disney fans who want more than trivia, for teachers looking for a fresh way into literary analysis, and for anyone who’s ever wondered what a story looked like before Hollywood got to it. No prior knowledge of the source material required — just curiosity.

This isn’t a book about ranking movies against their originals. It’s a book about following a story as it travels — through centuries, across languages, through different tellers with different purposes — and landing, finally, on a movie screen.

“These stories came from somewhere. That somewhere is usually darker, stranger, and more interesting than the movie.”

From Chapter 1 — Snow White

“In the version most people grew up with, Snow White is a gentle girl who waits for rescue. In the Brothers Grimm original, she’s seven years old — and she survives three separate murder attempts before the Queen ever touches an apple.”
