Samuel Otten, who shot the video, said (spoilers): "Several Bruce Wayne stand-in's and stunt doubles were on set today. You can see them blocking out a scene involving the rescue of a small girl and the collapsing of a large piece of the Wayne Financial building. Based on city buses and police cars, this is presumed to be in Metropolis, not Gotham. I don't know that any of these are Ben Affleck himself, but you can be the judge. Probably him in the first sequence, but definitely not the later ones. At the very least, it's Bruce Wayne."
Coming to theaters on May 6, 2016, the Zack Snyder-directed action adventure stars Henry Cavill, Ben Affleck, Gal Gadot, Amy Adams, Laurence Fishburne, Diane Lane, Jesse Eisenberg, Jeremy Irons, Holly Hunter and Scoot McNairy.
