Synopsis
In a futuristic kingdom, there's a princess named Mary who was born with a very unique personality: Overly expressive, super-intelligent, wondering, thrill-seeking, prank-loving, and artistic. However, her mother has taught her that non of those are the qualities of a princess, so she has repressed all of those qualities since childhood, and none of those has ever reutrned... until her teenage years, where she suddenly wakes up in strange places, like the museum, or having done things she dosen't recall, such as throwing a pie at her mother. One day, when Mary was knocked unconscious, she discovered the truth: The long supressing of her qualities has caused Mary to develop seven separate personalities: Angry, Prankster, Genius, Extreme, Emo, Wonder, and Artist. While each personality cares for the other, they just can't work together due to their disitinct actitudes and/or actions. However, Mary must make her alternative selves work together when a threat comes to their kingdom.

 * Auli'l Cravalho as Mary: A princess with seven alternative personalities, all whom must learn to work together in order to protect their kingdom. Director Jennifer Lee said that "her alternative selves here work as an alegory for team work and self-acceptance", and that "while in other films somebody has to overcome his or her other personality, they all have to learn to co-operate here". Eve would be inspired by Jim Carrey's performance in Me, Myself & Irene (2000) for her performance in the film. Eric Goldberg would serve as the supervising animator for Mary's Genius petsona, which would manifest in their mind as a drawing on a blackboard, while Bruce W. Smith would serve as the supervising animator for Mary's Angry persona when she manifest physically as a shadow.

Music
Kris Bowers would compose the film's score. Bowers would create a score that "didn't focused a lot on the psychological concept, but more on the heart and fun in the story. And with little psychological stuff because it still plays a role in the movie". Bowers would describe Mary and her alters' theme as "super dynamic", as he has to change it in order to represent each personality "yet still keeping a same vibe in order to make clear that they are part of the same being". Bowers would compose a "sad and repressed" theme for Alexandra, an "strict" theme for Martha, and a "dangerous and power-hungry-feeling theme" for David".

Bowers would also produce and curate a soundtrack featuring songs for the film, which would be performefd by several artists including Tiw Savage, Mr Eazi, Beyoncé, Andy Grammer, Nial Horan, Patrick Basca, and X Ambassadors. Bowers would compare the film's soundtrack to the soundtrack for Sony Pictures Animation's Spider-Man: Into the Spider-Verse (2018), in the sense that "it has songs that work perfectly well as pure pop songs to listen in the radio, but at the same time fit perfectly with the film's story".

Reception
On Rotten Tomatoes, the film would have an approval rating of 89%, with an average rating of 8/10, based on 227 reviews. The website's critical consensus would read, "Thanks to a light-hearted tone and a great story about self-acceptance and teamwork, Disney's Multiple manages to tackle the theme of split personalities in a stye that distinguish itself from other movies thanks to its wonderful voice acting, awesome visuals, charm, and timeless appeal". On Metacritic, the film would have a weighted rating of 79 ot of 100, based on 44 reviews, indicating "generally positive reviews".

Animated series
An animated television series set after the events of the film, also titled Multiple, would be produced by Disney Television Animation, and created by DuckTales (2017) creators Frank Angones and Matt Youngberg. Cravalho, Thompson, and Eve would reprise their roles from the film, while Kris Bowers would return to compose the score. The series would center on the individual lives of Mary and her other personalities, and how those lives affect the other personalities and their relationships. According to Angones, the series would be created because he and Youngberg would feel that, while the film explored well the friendship between Mary's personas, it mostly told "Mary's story", while a TV show would allow the other personalities to be gurther explored, and to tell stories from each persona's point of view.

Trivia

 * Additionally, the hat that Mary's Extreme persona would wear would strongly resemble the one used by Clopin througth The Hunchback of Notre Dame.
