On February 17, 2021, WarnerMedia announced that a television film was in development under the working title The Amazing World of Gumball Movie. On September 21, 2021, Cartoon Network announced that the upcoming film had been greenlit under the title The Amazing World of Gumball: The Movie!, with original series creator Ben Bocquelet serving as director and executive producer. The film would focus on Gumball's biggest fan finding a missing episode from the television show and accidentally opening a portal that connects Gumball's cartoon world to his own. After meeting the characters, they'll join Gumball, Darwin, Anais, Richard, and Nicole in saving Elmore from a nefarious menace looking to overtake the town. It would act as the "epic conclusion" to the original series and establish the world for a new accompanying show with the working title The Amazing World of Gumball: The Series. On August 22, 2022, the film was announced as one of six projects that will no longer be debuting on the streamer HBO Max, but will instead be shopped at a different outlet. Bocquelet later said in a September 1, 2022 tweet, that the film's fate is "a bit of a Schrödinger's cat question". He still expressed hope that the film will continue at some point.

The idea is to change the television film to theaterical and release on other streaming services like Netflix.  Similar like they did for The Day the Earth Blew Up: A Looney Tunes Movie but it distributed by GFM animation.

Warner bros doesn’t want to distributed theatrically, it should picked up by Universal, A24, GFM or maybe Amazon. Hulu would be a good pick if they want it for streaming film exclusive.
