The Disney+ documentary series "Disney Worldbuilders" explores the multi-generational contributions of the Iwerks family to Disney's technology and imagination [1, 2].
The series highlights the intersection of technical innovation and creative storytelling. By documenting the work of the Iwerks family, the project illustrates how specific inventions allowed the company to translate large-scale conceptual ideas into tangible real-world experiences [1, 3].
Filmmaker Leslie Iwerks directed the project, which focuses on the lineage beginning with Ub Iwerks and continuing through her father, Don Iwerks [1, 3]. Don Iwerks, a recognized Disney Legend, was known for camera innovations that the company said still power the magic seen on screen [4]. He died at age 96 [5].
Across four episodes [2], the series details how the family's work is integrated into the company's history, from early animation to modern immersive attractions [3]. The production serves as both a historical record and a personal exploration of the creative process for Leslie Iwerks.
“My dad taught me that imagination is a muscle you have to work out every day,” Iwerks said [1].
The documentary said that the Iwerks legacy is woven into every frame of the company's history [3]. While some reports indicate the series is available on both Disney+ and Hulu, other sources state it streams exclusively on Disney+ [1, 3]. The series premiered in 2024 [2].
““My dad taught me that imagination is a muscle you have to work out every day,” Leslie Iwerks said.”
The focus on the Iwerks family underscores a recurring theme in the entertainment industry where technical engineering is as critical to the final product as the artistic vision. By highlighting the transition from early animation to immersive theme park attractions, the series contextualizes Disney's growth not just as a storytelling entity, but as a hardware and optics innovator.
