HBO Max has announced this morning that Seth Grahame-Smith (Abraham Lincoln: Vampire Hunter; The Lego Batman Movie) has been tapped as showrunner for their upcoming Green Lantern television series.
[A previous version of this story incorrectly stated that it would be titled Lantern, but it appears as though no official title has been assigned just yet]
Green Lantern has already received a straight-to-series order for ten episodes, with Grahame-Smith and Marc Guggenheim (Arrow; Legends of Tomorrow) co-writing the first hour. While the scripts are still being broken down, the series is tentatively expected to begin production mid-2021, likely suggesting it may not debut on the streamer until sometime in 2022.
As for who's involved, the main characters will be Guy Gardner, Jessica Cruz, Simon Baz, and Alan Scott with fan-favorite Kilowog and classic DC Comics villain Sinestro also slated to appear. No word on casting yet, but it seems probable that we won't hear anything on that front until, at least, early next year.
For now, Hal Jordan, John Stewart, and Kyle Raynor will not be involved with the series in any capacity, which begs the question whether Warner Bros. may be saving their most popular Lanterns for a big screen adventure.
There aren't many additional details at this time, but Green Lantern is believed to be executive producer Greg Berlanti's (The Flash; Supergirl) most ambitious and most expensive series yet.
