Mickey & Minnie in: Deep Caves

Mickey & Minnie in: Deep Caves would be a 2029 hand-drawn animated adventure comedy short directed by Eric Goldberg and written by Lauren MacMullen and Bruce W. Smith, who would also executive-produce the film alongside Jennifer Lee, while Dorothy McKim would produce the short. Produced by Walt Disney Animation Studios for Walt Disney Pictures, the film would star the voices of Chris Diamantopoulos, Kaitlyn Robrock, and Jim Cummings, while Kris Bowers would compose the score.

Development on a hand-drawn animated Mickey Mouse short would begin in early 2027, with Goldberg set to direct the short and MacMullen and Smith set to write it. The short's cast would be announced in mid-2027, while animation would begin in late 2027. The filmmakers would use hand-drawn animation for the short with the intention of evocating early Mickey Mouse shorts.

Mickey and Minnie in: Deep Caves would be released on May 22, 2029, alongside the film Divided, and would become a critical success, with critics particularly praising the short's use of hand-drawn animation, direction, writing, vocal performances, and musical score.
