Grahame-Smith will also serve as showrunner. The 10-episode show will be written by Seth Grahame-Smith ( The Lego Batman Movie) and Marc Guggenheim, who co-created Arrow with Berlanti and was a writer on the 2011 Green Lantern movie starring Ryan Reynolds - hopefully this series is more successful. Greg Berlanti ( Love Simon) is adding to his already impressive list of superhero TV shows with an upcoming Green Lantern series for HBO Max, and Deadline reports that one of the main characters will be Alan Scott, the original Golden Age Green Lantern, and a gay man.
