Disney Granddaughter's Secret Set Mishap Revealed

Joanna Miller, granddaughter of Walt Disney, recently disclosed a long-kept family secret concerning the set of the 1964 film Mary Poppins. During visits to the studio, Miller and her siblings were permitted to explore the grounds while their grandfather worked. On one occasion, they ventured onto the Mary Poppins set and accidentally toppled a carousel horse.

This incident, which occurred nearly 60 years ago, was never revealed to Walt Disney. Miller shared this memory at a D23 event commemorating what would have been Disney's 125th birthday. The event also featured insights from other notable figures who worked with Disney, including Imagineer Bob Gurr and animator Floyd Norman.

The D23 convention, held in Anaheim, California, regularly honors Walt Disney's enduring legacy through various presentations and exhibitions. The company continues to celebrate its founder's impact, notably through projects like the 2023 short film 'Once Upon a Studio' and updates to attractions such as Disneyland's 'It's a Small World'.
