Granted the video is super short, we only really get to see three separate scenes getting teased here. First we get to see a slight change to the resurrected Superman finding his monument/tombstone. Then we see the cut footage of Victor Stone, AKA Cyborg, before his fateful accident. Lastly we get a brief glimpse at Aquaman, Wonder Woman and Flash about to team up to fight Superman.
Less Than Minute Gives Us More Confidence Than the Theatrical Version
