In the post-Endgame world, Anthony and Joe Russo have begun early work on a slew of interesting projects – and now comes word on two further such projects for the brothers Russo.

From San Diego Comic-Con, the Avengers: Endgame directors have revealed that they are developing live-action movie takes on both Grimjack and Battle of the Planets.

For Grimjack, Anthony and Joe will not be on directing duties, but they will be overseeing the adaptation for Amazon. Defiance’s Kevin Murphy is currently on board to pen the screenplay for the film, with the Russos producing through their AGBO banner. Created by John Ostrander and Timothy Truman, Grimjack centres on a sword-wielding war veteran called John Gaunt as he and his team head to the pan-dimensional city of Cynosure.

As for Battle of the Planets, Anthony and Joe Russo have teased that they may end up directing this one – although that is far from set in stone right now. Based on the iconic Science Ninja team Gatchaman anime series, Western audiences will be more familiar with the Battle of the Planets series that focused on G-Force as they sought to protect the Earth from alien menaces.

These projects, of course, come in addition to the Russo brothers developing a Stan Lee documentary, working on a Magic: The Gathering animated series – which they’ve recently teased may also get a live-action movie – and producing new takes on the likes of The Thomas Crown Affair and Poltergeist.

Expect more on all of these projects as they continue to develop.
