This means that Warner Bros. will have to get moving on the still developing project, while balancing the upcoming releases of Shazam!, Joker, and Birds of Prey (And the Fantabulous Emancipation of One Harley Quinn).
The Green Lantern Corps. movie is one of the many DC projects that have been announced, with the blockbuster currently set for a 2020 release.
The DCEU hasn’t used the Green Lanterns at all thus far, save for a brief cameo in Justice League’s flashback sequence.
