While the video doesn't feature Ben Affleck himself as Bruce Wayne (though unconfirmed reports claim that is him in the first run-through), we do get to see his stand-in rehearsing a scene where he saves a young girl. This scene is reportedly set inside Metropolis, not Bruce's hometown of Gotham, according to a report from Twitter and YouTube user Samuel Otten. While Bruce is seen here at the demolished Wayne Financial building featured in previous set photos, it has not been confirmed if this is new city damage, or if this is the aftermath of Man of Steel's climactic end battle which found Zod and Kal-El wiping out most of Metropolis.
Take a look at the video, along with Samuel Otten's description of what he saw on set, then continue on for a slew of new images shooting continues.
