Once Upon a Studio

Once Upon a Studio is a 2023 American live-action animated fantasy comedy short film written and directed by Dan Abraham and Trent Correy. Produced by Walt Disney Animation Studios, it is commissioned for the occasion of the Walt Disney Company's centennial. In the film, Disney characters come to life from pictures and animation frames hanging on the walls of the Roy E. Disney Animation Building following the end of a usual work day. Combining computer graphics and traditional animation on live-action backgrounds, the short features characters from the majority of the studio's works made up to that point. The film is dedicated to Burny Mattinson, the company's longest-serving employee, who makes a cameo appearance and died eight months before its release. Once Upon a Studio premiered at the Annecy International Animation Film Festival on June 11, 2023, and had its first public screening in the United States on ABC's The Wonderful World of Disney on October 15, along with the world television premiere of Encanto.
