The original series author Akira Toriyama once again provides the original concept, writing the script (including every detail of the dialogue), and drawing character designs for the film (changing pre-existing characters to their manga designs rather than those used in the anime). It has been said that he is even more invested in this film than the prior three he wrote.
Production began before the release of Dragon Ball Super: Broly.
At Comic-Con 2021, more details were announced as well as the film's title. Character designs for Piccolo, Pan, Krillin and a new character(s) were shown, as well as the design for Piccolo's home. The way Goku will be animated was also shown in a brief preview.
- Prior to its announcement, a leaked forum on Toei Animation Europe's official website accidentally leaked the news of the new Dragon Ball film two days before its initial announcement.
