My Little Pony: Equestria Girls - Interdimensional Exchange

My Little Pony: Equestria Girls - Interdimensional Exchange would be a 2025 American animated musical adventure film based on the My Little Pony: Equestria Girls franchise by Hasbro, itself a spin-off of My Little Pony: Friendship is Magic. Directed by Ishi Rushell and produced by Katherine Crownover, the film's screenplay would be written by Meghan McCarthy and Nick Confalone from a story by McCarthy, and would be produced by Allspark Animation and Netflix Animation. The film would star the voices of Rebecca Shoichet, Tara Strong, Ashleigh Ball, Andrea Libman, Tabitha St. Germain, Cathy Weseluck and Kathleen Barr. The score would be composed by William Anderson, with songs by Daniel Ingram and Josh Haber.

Development on a Netflix-exclusive Equestria Girls film would begin at Allspark in early 2022, with recurring Equestria Girl director Ishi Rushell set to return as director and McCarthy and Confalone set to write the film. In late 2022, the cast from previous Equestria Girls media would be announced to reprise their roles in the film. Animation would begin in late 2022, and would be worked on for two years. The story would be set shortly after the special My Little Pony: Equestria Girls – Spring Breakdown becuase Rushell wanted to explore "how things go when the human and pony worlds collide as strongly as they did at the end of that special". Animation for the film would be done with Toon Boom Harmony because Rushell would want it to have a stronger quality than previous Equestria Girls media.

My Little Pony: Equestria Girls - Interdimensional Exchange would be relased on July 3, 2025, and would receive a positive critical reception. Critics would praise the film's themes, screenplay, directing, vocal performances (particularly Schoichet, Strong, and Libman's), musical score, songs, and animation.
