It’s the first cut from The Snyder Cut.
Director Zack Snyder tweeted out the first new look of his original edit for Justice League (see video below), the DC superhero team-up movie that Snyder had to bail out of during post-production and reshoots due to a family tragedy. Avengers 1 & 2 guru Joss Whedon took over re-write and directing duties to complete the film for its release in November 2017. (You can read more about The Snyder Cut here.)
Snyder’s tweet is not a trailer. Instead, it’s one brief clip of Diana Prince (a.k.a. Wonder Woman) discovering an artifact that prophecies Darkseid, the would-be main villain of the now mostly-defunct DCEU.
The unseen person speaking in the clip is Jesse Eisneberg‘s Lex Luthor. What he whispers is largely indecipherable, save for his final words “…the God is dead.” (I’d recommend clicking on the close-caption “CC” option in the YouTube video below.)
The clip ends with the first glimpse of Darkseid in all of his CGI bombast, leading an apparent army.
Whedon’s version of Justice League replaced Darkseid with Steppenwolf, a big CGI alien monster. Given that overhaul, one assumes that this clip is meant to confirm that Darkseid will take center-stage of The Snyder Cut, as originally planned.
Snyder’s tweet also suggests that more footage will be revealed on August 22 during the virtual event DC FanDome.
Justice League: The Snyder Cut will debut exclusively on HBO Max in 2021.
