The Snyder Cut of Justice League opens in theaters probably never.
Suddenly Snyder and the cast were all tweeting the #ReleaseTheSnyderCut hashtag, and Snyder was posting pictures of the physical print of the Snyder Cut to prove it was a real thing.
Obviously if the Snyder Cut looked like this it would be a very different movie than Justice League.
The Superman on the poster is also in a black costume inspired by the character’s rebirth during the famous “Death of Superman” storyline that influenced the plot of Batman v Superman: Dawn of Justice.
