Talk:The Lego Unikitty! Movie (2021 film)/@comment-31947717-20180303225930

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.
