An extra working on Batman v Superman: Dawn of Justice has spilled some new plot details to the Superman Homepage, which sheds new light on the previously-reported Washington D.C. setting. Obviously, there will be potential spoilers below, so read on at your own risk.

Last month, we showed you some photos from the Lake Orion, Michigan set that featured the Wayne family mausoleum in a field, with a number of vintage cars also spotted on the set. This unidentified extra confirms the speculation that this scene will be a flashback to the funeral of Bruce Wayne's parents, which also features Jeremy Irons as Alfred Pennyworth.

"The first scene we filmed was with Jeremy Irons. It was out in a field with young Bruce Wayne. A flashback to the Wayne funeral. The small set was really cool with the hearse vehicles sporting Gotham license plates."

The second scene this extra was present for explains why part of the movie is set in Washington D.C., which involves another, more surprising funeral.

"The second scene I was involved in was situated in a half-stadium style set surrounded by tall green screen walls. Henry Cavill was on set dressed as Clark Kent, but did not film with us that day. This scene was a parade scene to take place in Washington D.C., obviously the CG effects for the surroundings would be placed in post production. The parade, we were told, was the funeral for the President of the United States."

This is the first we've heard that the President of the United States being a part of the story, and it isn't known yet who is playing POTUS. It also isn't clear how far into the plot this funeral takes place, and who is responsible for his death. Naturally, none of this has been confirmed, but the unidentified extra also sent along a photo from the set, showing a massive green screen wall that was used for the President's funeral.

Naturally, none of this has been confirmed, but what do you think of these new details? Chime in with your thoughts below, and stay tuned for more news as Batman v Superman: Dawn of Justice begins production.
