Warner Animation Group had already begun the process of starting development of movies with budgets of around $150 million. The intellectual property for these films was meant to be supplied by Warner Bros. Animation, Hanna-Barbera (Warner Bros. Animation's in-name only division), Cartoon Network and Turner Entertainment (also both Time-Warner divisions) among others and included The Flintstones, The Jetsons, Scooby-Doo, Samurai Jack, Adventure Time, Cow and Chicken, and more, and of course, Codename: Kids Next Door. Cartoon Network had been approaching the original crew from the television series to make a high-profile, animated theatrical feature-length film adaptation and had long wanted to partner with Warner Bros. Pictures to release a Unikitty film given the network's extraordinary legacy in the world of animation, including some of the most enduring characters on cable television history.

Creators Phil Lord and Christopher Miller agreed to make a feature film version of the show with the promise it would be the first of a planned trilogy. During development stages of the film, he and his co-writer and co-producer Dan Lin intended to revisit some of the greatest films of the time, with Scarface and The Dark Knight having the core inspirations for the film.

The feature animation was handled by Snipple Animation Studios in Manila, the Phillipines. The crew used the same processes from the original television series in the making of the film, most notably the 'skroutlines', which was a seamless blend of a more traditional screenplay with a more simple outline which resembled strong short stories and gave the storyboard artists such as Kelsy Abbott, Mike Olsen, Aaron Preacher, Chad Quandt, Ed Skudder, Aaron Waltke, and Lynn Wang all the creative and aesthetic freedom neccessary. Dan Lin, Phil Lord and Christopher Miller themselves provided the film's animatics.

Famed comic book artists Ed Skudder, Aaron Waltke, and Lynn Wang and animation veterans William Reiss, Careen Ingle, Casey Alexander and Brock Gallagher also provided the film's storyboards. Dan Lin helped on the character designs and special effects work on the film. Another animation producer William Reiss also worked with Christopher Miller on the character designs of the film. Pencilled key animation sequences would be digitally inked-and-painted, enhanced and composited into backgrounds using Toon Boom Harmony.

Additional pre-production work was done at Warner Bros. Animation in Burbank, California where the series' pilot episode was produced. Animation was done at Snipple's facilities on Manila, Philippines.

The final animation was also provided by Wang Film Productions Co., Ltd. in Taipei, Taiwan, HGN Productions in Sao Paulo, Brazil, Denmark's A.Film, Terryglyph Productions in Dublin, Ireland, Yowza! Animation from Toronto, Canada, Sunwoo Entertainment from both Seoul, South Korea, and Los Angeles, July Films in Los Angeles, California, Toon City Animation in the Philippines, SPA Animagic and Estudio Moro in Madrid, Spain and Neomis Animation in Paris, France.

Brian Tyler composed the soundtrack for the film with Thomas Newman and Lorne Baffe serving as the soundtrack producers. In addition to using the original series on the film, he also composed themes for each Unikitty operative. Unikitty's awesome score was the major focus and he also composed themes for Unikitty, Puppycorn, Dr Fox, Richard, and the others. The music score was recorded at Warner Bros. soundstages in Burbank and mixed at Remote Control Productions in Santa Monica and and there was also music recorded at Abbey Road Studios in London, England. The sound design work was done at Skywalker Sound in Marin County, California and Warner Bros. Animation in Burbank, California.
