Directors Joe and Anthony Russo announced at their panel at San Diego Comic-Con 2019 that their AGBO Studios is developing an adaptation of the Gatchaman (Battle of the Planets) anime series. The Russos added that they could not say if they will direct the project, nor could they say if the project will be animated or live-action. However, they said that if they do direct, it would be in live-action.

The first Gatchaman anime premiered in Japan in October of 1972. The original series premiered in the United States in 1978.
