Greg Berlanti planning series for HBO Max.

I'd love to see a GL series. I don't think Berlanti should touch another comic book show or any show, for that matter.

How to tackle a GL series. Hmmm. They will try to put lots of emphasis on drama since that will chew lots of time in the name of budget. They need someone who can create a compelling dramatic element and also portray space adventures without being boring. James Gunn comes to mind but he is too silly for this property. Joss Whedon knocked it out of the park with Firefly but look what he has done since. I think the show is at risk of seeming stupid almost no matter what they do (similar to Fantastic Four) so I wonder if an off-beat approach is called for. Something Lynch-esque. Maybe Hiro Murai or Dennie Gordon from the Legion tv show.

Isn't it supposed to be an animated series?

Since Green Lantern Corps is reportedly going to "reimagine the team," it already sets up a way for the TV characters to join them down the line. The first film should naturally focus on Stewart and Jordan's relationship, assuming they're sticking to the original concept. Since HBO Max is working heavily with the feature side of Warner Bros.' DC films, it enables them to work out timelines as well as how the show and film would fit together naturally. Whether Green Lantern season 1 takes place before the events of Green Lantern Corps or vice-versa is irrelevant because the plot could easily have the two groups be spread across the universe on their own missions. Eventually, something affecting all of them could be what brings them together, whether it's on the TV show or in the film franchise.

A way to include Kyle Rayner would be if he becomes the crossover character between the two properties as he's interesting enough not involved with either one right now. If Warner Bros. is going to these lengths to introduce pretty much every famous Green Lantern in live-action, then Kyle can't be far away. A possible scenario would be that Kyle is actually already out there on his own adventures but ends up facing something that forces him to bring together the other Lanters. If the HBO Max drama and the DCEU film were to connect, it'd be a unique way for Warner Bros. to build up to iconic storylines like Blackest Night and Sinestro Corps War. By letting the Green Lantern mythology be fleshed out within both projects, it makes it more organic to eventually get to those bigger comic arcs. If there is a time where Hal, John, Alan, Simon, Jessica, and Guy are in live-action at the same time, it'd be a wasted opportunity to not connect Green Lantern and Green Lantern Corps in one way or another.

It's being reworked to focus on John Stewart. They should just make a new movie already.
