Batman v Superman is currently filming in Detroit and when the DJ's on a local radio station 97.1 The Ticket started saying disparaging things about Aquaman… things got interesting. A man called in and identified himself as Zack and said he was on the way to the set. He said he called in to defend Aquaman. When the DJ's asked why the character would be in the movie, "Zack" said he didn't want to give anything away but the character could: "cut the flesh of Superman if they came in contact … he's super strong … It's not to say that he's in the movie or anything like that but … he has the potential to be bad ass."
Was this Zack Snyder? The voice sounded like his and he would be in Detroit… and the call was from a Los Angeles cell… so it could be.
Here is the segment from the show.
