MovieWeb has posted an unofficial behind-the-scenes video taken during filming of "Batman V Superman: Dawn of Justice," which features stand-ins and stunt doubles for the Bruce Wayne character. The video does not appear to have a Ben Affleck appearance -- but the doubles certainly look like the actor.
The footage, filmed on August 5, features Bruce Wayne rescuing a girl from the wreckage of a collapsed building, likely in Metropolis, not Gotham City. As MovieWeb notes, it's unknown whether the collapsed building -- said to be a Wayne Financial branch -- is a result of the widescale destruction which occurred during Superman's battle with Zod in "Man of Steel" or some completely separate damage.
"Batman V Superman: Dawn of Justice" opens May 6, 2016.
