The fifth installment of DC Extended Universe "Justice League" scheduled its premier this coming November 17, 2017. A superhero film based on DC Comics and distributed by Warner Bros.
After the movie "Batman v Superman: Dawn of Justice", Batman and Wonder Woman convene the metahumans in every corner of the earth to fight the threats from Steppenwolf and the Parademons; who are after the three Mother Boxes on Earth. They will recruit Cyborg, The Flash, and Aquaman — who compose the titular Justice League — to defend the earth after the death of Superman.
A report from The Wrap, well a spoiler, Superman may possibly return in the movie after his climactic death on "Batman v Superman". The other one is Darkseid's appearance on the prologue of the film as it introduces the New God.
Ciaran Hinds from "Game of Thrones" is the main villain as he plays the role of Steppenwolf; he will go the earth to collect the three mother boxes from Amazonians, mankind, and Atlanteans.
Another report from Uproxx, one of the intergalactic police force "Green Lantern Corps" will appear on the key sequence of the "Justice League" movie, though, the identity of the character is still unknown. Another question is, if the appearance will be just a glimpse or substantial.
"Green Lantern Corps" is an intergalactic police force that protects the DC Universe, created by the Guardians - immortal race from planet Oa. Hal Jordan, one of the member of the Corps led the station from earth. Along with him are Guy Gardner, John Stewart, and Kyle Rayner.
In 2011 Warner Bros. launched the movie "Green Lantern" starring Ryan Reynolds. Unfortunately, he will not play the role of Hal Jordan again; his replacement is not yet revealed.
While "Justice League" will come to theaters earlier, the schedule of "Green Lantern Corps" will be on 2020. The probable appearance of one of the intergalactic police is one of the best way to reintroduce the characters from the movie.
