Development
On July 4, 2009, RKO Pictures International, Agüero-Máynez Media, Figgelmünch Film Animation, Creators Syndicate, and Cookie Jar Entertainment announced that the film would be in production. The film took a total of 34 months to develop.

Writing
While the production of the film mainly took place in Puerto Chango, current Heathcliff writer Peter Gallagher served as a co-writer and Catillac Cats creator Jean Chalopin served as a screenwriter. Gallagher and Chalopin also served as creative consultants. Main writer Joachim-Friedrich Anschütz and main screenwriter Efraín Kindelán reviewed the 1984 cartoon's setting of the 1980's before drafting the script. They wrote several versions of the script until they finished the final draft the script. It took them six months to write. Dr. Ricardo Lopéz, a Puerto Changuese voice director, voice actor, and university professor who provides the Spanish voice of Riff-Raff, adapted and translated the script in Spanish.

Animation
The film was animated in Toon Boom Harmony with computer animated backgrounds. The animation was done by Figgelmünch Film Animation in their famous Francisco Franco Boulevard studios, while post-production (including the CGI backgrounds) and stereoscopic 3D services were done at Agüero-Máynez Media's studios in Alcapaz.

Background development and setting
Miguel Ángel Agüero, the film's director, did a scouting in various Northeastern United States and Southern Ontario locations in 2012 and took pictures of buildings, alleys, and drains.

Character development
During character development, all of the film's characters had to be approved by Creators Syndicate and Cookie Jar. The goal was for the characters to look like they were drawn in style of the series. Fans submitted new characters such as Trixie and the Purrson sisters, and the producers created new characters such as Yusuf Abd al-Rahman and Zakiya Chahuán (Cleo's Muslim parents), Jérémy D'Aboville and Lan Quốc Kiều (Riff-Raff's French and Vietnamese parents), Wordsworth W. Wordsworth II and Zoey Jackson (Wordsworth's military parents), the army of robots, and over 100 incidental characters.

Cast
The Spanish and German casts features well-known voice actors from Puerto Chango. While the English cast has a different cast from the original '84 cartoon, Danny Mann, Donna Christie, Derek McGrath, and Marilyn Lightstone reprise their roles from that cartoon.

Funding
The film was funded by Sunkist, Freia, Puerto Chango Bank, and TNT Fireworks.
