The third official trailer for Batman V Superman: Dawn of Justice surprised fans with the amount of presumed spoilers on display. The film expands the DCEU in a major way, introducing Ben Affleck's Batman, Gal Gadot's Wonder Woman, and the new trailer underlined the subtitle's lack of ambiguity: the film will lay all the framework for 2017's Justice League.

While some of the other traditional Justice League heroes will also be introduced in Batman V Superman -- such as Aquaman (Jason Momoa), Cyborg (Ray Fisher), and maybe Barry Allen/The Flash (Ezra Miller) -- one key member will still likely be missing: some version of Green Lantern. We know that the solo movie slated for 2020 has been retitled Green Lantern Corps and will likely feature multiple human versions of the Lanterns.

We still know almost nothing about Green Lantern Corps beyond some casting rumors, which suggested that DC/Warner Bros. was looking at Star Trek star Chris Pine to star as Hal Jordan rather than Steve Trevor in Wonder Woman (we know how that turned out); meanwhile, Tyrese Gibson (the Fast and the Furious movies) keeps reminding us how badly he wants to play John Stewart.

Now, Italian website Cinefilos (via Comicbook.com) reports they recently saw some Green Lantern Corps concept art at the Cinema Professional Days in Sorrento, Italy, which took place from November 30th to December 3rd. The art was evidently part of a larger video presentation outlining the future releases from DC Entertainment and featured Green Lanterns Hal Jordan and John Stewart.

Note that no images of this concept art are available, so take this with some salt as usual. With the film's title changed to reflect the introduction of multiple Green Lanterns, establishing the entire Corps at once is a way to distance it from the still-loathed 2011 Green Lantern film starring Ryan Reynolds, as well as further injecting some much-needed diversity into the realm of comic book movies by pairing Hal Jordan with John Stewart, the two most famous incarnations of the character.

The 2011 Green Lantern tried to do too much too quickly, and was not helped by tone-deaf direction and unconvincing CGI effects. The 2020 Green Lantern Corps will be part of an established cinematic universe by the time of its release, and we'll more than likely see a version of Hal Jordan and John Stewart showing up somehow in one of the DCEU films leading up to 2020 -- be it Aquaman, The Flash, Cyborg or one of the Justice League films.

As for the casting, there is no shortage of actors campaigning for the role, such as actor/rapper Common, who was cast as John Stewart for Max Max: Fury Road director George Miller's never-made 2007 Justice League Mortal and still wants to do it. With the cosmic side of the DC Extended Universe set up from the very beginning, we should probably expect some kind of reference to the Green Lanterns to show up sooner rather than later. Given the lesson learned in 2011, it's no surprise WB and DC are taking their time with this particular IP.
