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.

Trivia

 * The film would have a budget of 90 million dollars, making it the hightest-budgeted film in the My Little Pony franchise. According to director Ishi Rudell, this would be partially due to "Netflix's reputation on animation, which gave the studio the motivation to make this film as great as possible".
 * In the film, the human versions of Rarity and Applejack would be confirmed to be a same-sex couple, becoming a couple during the film's events, while the Pony version of Applejack would be confirned to have feeelings for the Pony version of Rainbow Dash, and the Pony version of Sunset Shimmer would be confirmed to have feelings for Princess Twilight. Rudell would state that "the rise of LGBTQ+ representation on animation really motivated [the filmmakers] to cemment the ships and making them undoubtly canon and official". On choosing the Pony version of Twilight over her human self as Sunset's love interest, Rudell would state it would be mainly due to Human Twilight already being on a relationship.
 * Upon noticing the Pinkie Pie's human counterpart in Pony form, Pony Applejack would ask Pony Pinkie Pie if she "cloned [herself] again", referencing the events of the My Little Pony: Friendship is Magic episode "Too Many Pinkie Pies".
 * After coming back from the Pony world, Human Pinkie Pie would say "Wow, an interdimensional travel can give you such a crick in the neck". This would be a reference to the 1992 Disney film Aladdin, where the Genie said a similar line after being released from his lamp.
 * Director Ishi Ruddell would later confirm that the line was an intentional nod to Pinkie Pie's supervising animator Eric Goldberg, who served as the Genie's supervising animator in Aladdin.
 * When Human Sunset Shimmer refuses her Pony counterpart's offer to redeem herself, Human Pinkie Pie would state: "That's odd. It usually works for us". This would be a nod to how nearly all the villains in the Equestria Girls franchise end up redeeming themselves.
 * The film would be the second film from the 4th generation of the My Little Pony franchise to be made througth hand-drawn animation, after My Little Pony: The Movie (2017), while all other productions were done with Flash animation. Coincidentially, both were done with Toon Boom Harmony.
