Though star Jason Momoa teased an announcement regarding Green Lantern's anticipated role in the upcoming Justice League film at Comic-Con International, when Warner Bros.' Hall H panel was said and done, fans hoping for a big reveal (possibly one involving Armie Hammer) were left wanting.

Well, sort of.

While Mr. Hammer didn't make a dramatic last-minute appearance on stage, and the subject of the Green Lantern Corps wasn't broached at all during the presentation save for a brief glimpse of the movie's logo (alongside comic art of Hal Jordan and John Stewart), the existence of the Corps -- or at least a corps -- has finally been mentioned in DCEU continuity thanks to the all-new Justice League trailer.

Following his arrival on Earth via a Boom Tube, the film's villain, Steppenwolf, runs down the list of reasons why Earth is doomed to bow before Darkseid. "No protectors here," the Apokaliptian bad guy intones over images of Aquaman, Wonder Woman and more. "No Lanterns. No Kryptonian. This world will fall, like all the others."

While this is not a confirmation that there will be a Green Lantern presence in Justice League, it does serve to illustrate just how important the Corps is/will be to the future of the DCEU. The studio has a Green Lantern Corps film slated to arrive in 2020 after all, and Tyrese Gibson recently confirmed that he and Warner Bros. just recently discussed the possibility of him playing John Stewart, a role he's been lobbying for since 2015.

As for Hammer, the Lone Ranger actor has been at the center of rumors tying him to the part of Hal Jordan for a while now. Warner Bros.' Superman, Henry Cavill, has done his part to tease Hammer's involvement via several posts on social media, and Hammer's name was among half a dozen others (including Tom Cruise and former GL star Ryan Reynolds) on a short list the studio is reportedly targeting for the role. And while Hammer has shot the rumors down, he's also done his part to help fuel them at the same time, teasing that a recent injury he suffered to his arm wouldn't preclude him from using a Green Lantern ring to form a giant fist.

Debuting in theaters on November 17, Justice League is a production of Warner Bros. Studios directed by Zack Snyder and starring Ben Affleck, Henry Cavill, Gal Gadot, Jason Momoa, Ezra Miller, Ray Fisher, Ciarán Hinds, Amy Adams, Willem Dafoe, Jesse Eisenberg, Jeremy Irons, Diane Lane, Connie Nielsen and J. K. Simmons.
