Once Upon a Studio is a 2023 American live-action/animated fantasy comedy crossover short film written and directed by Dan Abraham and Trent Correy, produced by Walt Disney Animation Studios and released by Walt Disney Pictures. In the film, Disney characters come to life from pictures hanging in the studio building following the end of a usual work day. Inspired by the studio's centennial on October 16, 2023, the short film was described as a "love letter" to Walt Disney Animation Studios by Correy and Abraham. The short's art style combines computer graphics, traditional animation and live-action. The film is dedicated to Burny Mattinson, who 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 showing on ABC on October 15, 2023, as part of The Wonderful World of Disney: Disney's 100th Anniversary Celebration. The short film premiered on Disney+ and Hulu on October 16, 2023, and the exact same date on Disney Channel, as part of Once Upon A Monday Movie Marathon, FX, FXM and Freeform. It will be screening in theaters with Wish on November 22, 2023.

A spiritual successor is a type of follow-up work that isn’t directly connected to the original story or universe, but still carries forward its essence through similar themes, style, and ideas—essentially acting as a sequel “in spirit.” Creators may do this for many reasons: to pay homage while avoiding legal ties, to continue exploring familiar creative ground without risking a direct sequel, or simply because their artistic voice naturally echoes past work. This concept appears across many forms of media, though it’s especially common in video games, where developers may retain the tools and design philosophy of a past project even if they no longer hold the rights to its name or characters. A related concept is the spiritual adaptation, where a work in one medium closely mirrors the tone and structure of another, almost feeling like an unofficial adaptation. Spiritual successors can sometimes feel like rebranded continuations of ideas from older or discontinued franchises, effectively serving as a kind of creative reincarnation. They often overlap with ideas like unofficial counterparts or heavily inspired works, and can even share the same creative teams. While they celebrate and evolve what came before, they stand apart as independent creations, occasionally even contrasting with or redefining the works that inspired them.
