Batman and the rest of the DCEU team go through the Knightmare timeline against Superman and Darkseid in a new Zack Snyder's Justice League 2 fan trailer. It has nearly been two years since Zack Snyder's Justice League finally got released on Max (formerly known as HBO Max,) and the Snyderverse audience is still hoping for the director's unproduced sequels to get made one day. Even though Warner Bros. Discovery has been working on their new DC Universe, there has been a campaign to get the Snyderverse moved to Netflix in light of the filmmaker's other properties on the popular streaming platform.
