More rumors today from the upcoming "Batman v Superman: Dawn of Justice", this time from an extra who worked ten days on the set who posted two bits of news to Geek Tyrant.
POTENTIAL MAJOR SPOILERS AHEAD
The first was that one scene involves Batman breaking into Lexcorp to steal kryptonite. Another is that Lex Luthor has gotten his hands on General Zod's body. That was followed-up by a report at Badass Digest who say those two mentioned rumors are correct, and adds some information as their own:
"Lex has been gathering pieces and debris from the World Engine and he has used them to synthesize 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."
They then posted an image of a silhouette that suggests Luthor is responsible for creating Doomsday.
