By now, fans would have assumed that Kryptonite will be of immense significance in the film for Luthor and Bruce Wayne/Batman (even though their intentions behind using it may be quite different).

An anonymous extra, who claimed to have worked on the Detroit set of Batman v Superman, revealed some key plot details to Geek Tyrant.

According to the extra, the ending of the film has already been filmed. One of the scenes shot featured Batman breaking into Lexcorp to steal kryptonite, and apparently Lexcorp had somehow gotten hold of General Zod's body.

He 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."

Badass Digest confirms this big plot reveal and also includes additional details:

"Lex has been gathering pieces and debris from the World Engine and he has used them to synthesise Kryptonite. Meanwhile he has also gotten ahold of Zod's corpse, and it is the key to his master plan to defeat Superman. He uses that tissue to... well, that would be spoiling. But Superman hasn't been defeated many times in the past. You can probably connect the dots from here," states the report.

Meanwhile, Ben Affleck, in his latest interview with Entertainment Weekly, spoke about playing Batman.

"I'm right in the middle of shooting now. It's a process that I'll probably have better perspective on when I'm done. I can tell you that every time I do a role, it's the responsibility of an actor to get their physical self as close to the role as possible. And Batman's obviously got a set of expectations that are tough. So I spent a lot of time working out.

"Before I took the role, Warner Bros. gave me a bunch of past reactions to casting and said, 'Are you sure you want to get into this? This is part and parcel of these movies now. There's a lot of active fans with a lot of opinions.' To me, having been through a certain amount of that, it doesn't really... Everyone's entitled to their opinion. I wouldn't have taken the part if I didn't trust my instincts in terms of the filmmaking. I think Chris Terrio wrote a terrific script. Zack's a great visual director. And there's an interesting take. I wouldn't have done it if I didn't think I could do it," Affleck was quoted as saying.
