After shooting for a month, the "Batman v. Superman: Dawn of Justice" production has done a good job of keeping set secrets of the film. However, now that the production continues, fans are finally getting some scoops on just what is happening on the massive film.

So far we have seen pics of Batman, Ben Affleck as Bruce Wayne, a shot of Superman in his revamped duds and a shot of Gal Gadot as Wonder Woman. All that aside, the production has been mum on any juicy details about the film.

Finally, some more details have surfaced thanks to Geek Tyrant. Please be aware that anything from this point on could be considered SPOILERS, so read them at your own risk!

Apparently the ending of the blockbuster film has already been shot and an extra in the film spoke with Geek Tyrant and has divulged just what he saw in his time on the set. It seems that Lex Luthor, played by Jesse Eisenberg, is a big part of the ending of the 2016 film.

"One of the scenes shot featured Batman breaking into Lexcorp to steal kryptonite, and apparently Lexcorp had somehow gotten a hold of General Zod's body," reported the extra. It looks like Lexcorp has acquired the corpse of General Zod and is trying to harness the alien's power to defeat Kal-El. It looks like the megalomaniacal Luthor has been collecting parts and pieces from the World Engine seen in "Man of Steel" to create Kryptonite to defeat Superman.

The extra, who worked on the film for 10 days, claims that the ending of the film has already been shot. He continues to remark that one of the scenes shot had Batman breaking into Lexcorp to steal Kryptonite.

The extra went on to talk about the timeframe of the movie and where it picks up, saying that it starts "as the battle between Superman and General Zod ends or is ending (which would explain all the damaged buildings and vehicles we've been seeing in photos) and Batman/Bruce Wayne is attempting to make his way to the Wayne tower in Metropolis," according to Geek Tyrant.

There is also a big unsubstantiated rumor that Doomsday may actually be in the film.

For now the best information we have is the footage that was screened at San Diego Comic Con last month. Surely more spies will continue to divulge news from the set as the production continues.
