Disney Impossible Creatures movie officially in development after a seven-figure rights deal for Katherine Rundell’s fantasy novel, Impossible Creatures.

Disney Impossible Creatures Movie

Walt Disney Studios has officially acquired the film rights to Impossible Creatures, the acclaimed fantasy novel by Katherine Rundell. As first reported by Deadline, Disney won a competitive auction for the project in a substantial seven-figure deal, setting the stage for what could become its next major family fantasy franchise.

A New Fantasy Adventure for Disney

The Disney Impossible Creatures movie will adapt Rundell’s beloved story of a boy who discovers a secret archipelago where all mythical creatures still survive, including griffins, dragons, selkies, and other legendary beings. Since its publication in 2023, the novel has drawn praise for its rich imagination, emotional storytelling, and environmental themes, making it a natural fit for Disney’s live-action lineup.

Author Katherine Rundell, known for The Explorer and Rooftoppers, crafted a world that mixes classic myth with heartfelt adventure. Fans have often compared Impossible Creatures to His Dark Materials and The Chronicles of Narnia, both of which inspired major screen adaptations.

Disney’s Winning Bid

According to Deadline, Disney’s live-action division secured the rights following a bidding war with several major studios. Based on their sourcing, Deadline stated that the finalists were Disney, Warner Bros, and Netflix, and execs from all three headed to London this summer to lay out their vision.

The studio’s leadership reportedly saw Impossible Creatures as a perfect blend of cinematic scope and family-friendly storytelling, two pillars of Disney’s modern strategy. While the studio has not yet announced a writer, director, or release window, early reports describe the Disney Impossible Creatures movie as a priority development project.

Rundell expressed excitement about working with Disney, emphasizing that the studio’s history of magical storytelling aligns with the heart of her fantasy world. She noted that Impossible Creatures carries a strong environmental message about protecting the wonders of the natural world, a theme Disney has explored across many of its animated and live-action projects.

Disney Impossible Creatures Movie: A Strategic Step for Disney

The acquisition comes as Disney continues to balance classic IP with new, original properties. In recent years, the studio has revisited legacy titles like The Little Mermaid and The Lion King while developing fresh franchises such as Jungle Cruise and Wish.

The Disney Impossible Creatures movie signals a renewed push toward high-concept storytelling built from modern literature rather than older fairy tales. With Impossible Creatures and its sequel, The Silver Road (published in 2024), Disney now holds a potential multi-film saga rich with characters, creatures, and mythology.

What Happens Next

No casting, production start date, or director has been confirmed, but sources close to the project suggest Disney plans to move quickly into active development. Given the book’s large-scale world and creature-driven visuals, the adaptation is expected to require extensive visual effects and creature design work.

Fans of the novel can expect updates in the coming year as Disney announces creative partners and production timelines. For now, the Disney Impossible Creatures movie represents one of the studio’s most exciting new ventures, a chance to build a completely original fantasy world for audiences of all ages.
