Antique books, fairy tales, maps and manuscripts representing the literary and folkloric sources behind classic animated films.

What Is Once Upon a Source?

Every Disney animated film you love started as someone else’s story first — a fairy tale collected by two German brothers, a children’s book written in a Highland cottage, a myth passed down for a thousand years before it ever reached a movie screen.

Once Upon a Source is a 24-chapter deep dive into those original stories — the darker, stranger, more surprising versions that came before the songs and the happy endings. Each chapter pairs one Disney film with the book, poem, or legend that inspired it, and shows you exactly what changed along the way.

Whether you’re a lifelong Disney fan, a teacher looking for a new way into literary analysis, or simply someone who wants “the real story,” this project was built for you. Start with a free chapter and see where the story really began.

What Readers Are Saying

“My first memory was of Mary Poppins, Bert, and the children hopping into the chalk art. I was 6 years old and first watched the movie with my parents. I didn’t know the full story until I saw the movie Saving Mr. Banks. It was quite an eye opener”

— Chris Huffnus 


Mary Poppins: The movie opens your imagination to the possibilities of anything. You never know where your day will lead, so always expect the unexpected. Roll with the punches and make the best out of a bad situation. Also remember to laugh on the ceiling, as it will make you feel much better.

— Christopher L. M. Cox II

The Lion King:
This story is a childhood memory I will pass on to my children, friends and family. The special gift a teacher gave to a struggling student. Childhood adventures with my best friend and cousin as we reenacted scenes on a backyard hill full of tall grass and large boulders that was our pride lands.
