Avengers: Endgame directors Joe Russo and Anthony Russo held a panel today at San Diego Comic Con where the director pair revealed a slate of new projects now that work on Avengers is done. There, the Russos announced that they are producing adaptations for two classic franchises: Grimjack and Battle of the Planets. Although the Russo's Comic Con panel focused on their work directing Avengers: Infinity War and Endgame, the two got a chance to go into detail about their other, non-Marvel projects.
