Snyder did a stream/commentary of
BvS a week or so ago talked about some more deets. Apparently he's now selling merchandise with "Zack Snyder's Justice League" on it for charity. Which would probably be the name for any Snyder Cut.
The big thing he revealed is confirming that the "unfilmable" version of
Justice League was essentially like
Endgame, starting after Darkseid wins and the Anti-Life Equation has conquered the planet. They would form the League "first" in that future to send Flash back to Bruce and Diana to form it sooner. I assume this would also be related to why they had to bring Supes back to life faster. He had mentioned before that the League fighting Superman scene in
Justice League was kept over and reworked.
The "Knightmare" in
BvS was going to be how the world looked, which is why he was talking about it.
It's funny that now, Warners would probably green light the whole Snyder "Trilogy" if he was pitching it to them fresh rather than calling it unfilmable and being horrified at what he was planning without their oversight.
They're producing a New Gods movie, they prefer the "darker" tone to Marvel supposedly, they've signed off on other ideas they were resisting to try and beat Marvel to them, Wonder Woman and Aquaman are both hits,
Endgame made billions, etc.
My offer to Warners: I will trade never getting the Snyder Cut for getting an unlimited budget Snyder shot scene of Darkseid's victory speech from
Final Crisis for someone else to use in their eventual guaranteed League/Superman vs. Darkseid film unedited.
