The night before the Google NEXT'25 conference, Google explained how it used Google Cloud services and artificial intelligence technology to bring the 1939 film "The Wizard of Oz" to life in the Sphere, a giant spherical theater in Las Vegas.
To present a film shot on film in 1939, using a 4:3 aspect ratio and a resolution much lower than today's specifications, on the Sphere's internal 16K resolution OLED display screen, and to match the immersive curved screen inside, it is obviously not as simple as just using artificial intelligence to improve the image resolution.
The project combines the technical resources of Google Cloud and Google DeepMind, and also collaborates with Sphere Studios, California software company Magnopus, and Warner Bros. Discovery.
To maintain a better viewing experience, it's not enough to simply improve the image quality and enlarge it to fill the entire screen. This can cause viewers to feel excessive visual pressure. Therefore, the best approach is to use artificial intelligence to generate more content within the original screen area, so that the size of the characters can be more in line with the natural viewing experience.
To ensure a more natural and appropriate overall presentation, Google also had to adjust specific details, such as camera angles and character positioning, for optimal viewing on the Sphere's giant screen. For example, during the Cowardly Lion's first appearance, the camera initially focused on the Scarecrow and the Tin Woodman. Then, as the scene shifted to Dorothy hiding in the distant bushes, Google had to further "zoom in" the already crowded scene and make it fit more comfortably on the Sphere's screen.
Throughout the production process, Google leveraged its AI-generated tools, Imagen and Veo, combined with Gemini AI technology. Using only the original film footage as source material, without adding any new lines, dialogues, or songs, the 1939 film "The Wizard of Oz" was brought to life on the Sphere screen in its original form. This was complemented by a 4D immersive experience, providing a more engaging viewing experience.
When producing this project, in addition to using existing film shooting content, the Google team also collected a large amount of materials such as shooting scripts, production illustrations, photos, set materials, and music scores, so that artificial intelligence could refer to these materials for training, which greatly improved the image quality of the film, and also allowed the characters to perform in a wider range of scenes, ensuring that the presentation was faithful to the original.
The film will be released at Sphere on August 8 this year, and Jim Dolan, Executive Chairman and CEO of Sphere Entertainment, anticipates that the integration of innovative technologies will make the physical cinema experience even more extraordinary, and therefore anticipates that more innovative technologies will be integrated in the future to promote different experiences.
