Fans are eager to see more footage from Zack Snyder's upcoming Justice League, which will feature DC icons like Superman, Wonder Woman, Batman, The Flash, Aquaman, and Cyborg teaming up for the first time on screen. A recent rumor suggests that seeds will also be planted for another big DC franchise.
In a recent article covering what is known about Justice League thus far, The Wrap says "a member of the Green Lantern Corps. will be seen in Justice League in a key sequence."
Up until now the studio has all but completely denied that Green Lantern is even a part of this current phase of DC films, as Green Lantern Corps isn't scheduled to hit until 2020. Many assumed that was in part due to the poor performance of their previous Green Lantern film.
If there is going to be a Lantern in Justice League, which would be a great way to reintroduce the character to the film audience, it will most likely be Hal Jordan, who would hopefully be a part of whatever the Justice League sequel turns out to be.
Previous rumors point towards multiple Green Lanterns from sector 2814 in the eventual Green Lantern Corp film, likely consisting of John Stewart, Hal, and possibly either Guy Gardner and Kyle Raynor.
Fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.
The Green Lantern Corps movie will be released in 2020. Justice League will be released in 2017.
