Following an announcement last week that Sphere Entertainment was creating an immersive version of The Wizard of Oz for its unique Las Vegas venue, we now have more details on how companies like Google and Magnopus are using AI to enhance the 86-year-old film to fill the Sphere’s massive 160,000-square-foot semi-spherical screen.

But a collaboration between Google’s Cloud and DeepMind research divisions didn’t only rely on off-the-shelf AI-upscaling techniques to create a new version of The Wizard of Oz with enough resolution for the Sphere’s 16,000 pixel by 16,000 pixel screen. The team at Google used “fine-tuned Gemini models, Veo 2, and Imagen 3 to intelligently enhance the film’s resolution, extend backgrounds, and digitally recreate existing characters who would otherwise not appear on the same screen.”
