Continuity mistake: When Batman goes to save Martha, he pulls the wooden box with his gun and throws it at one bad guy. The guy's head hits the wall, leaving blood. Later on, you still can see the dead guy but there is no blood on the wall any more. The blood appears again when Batman is about to finish off the last person who was stabbed and pinned against the wall. (02:17:30 - 02:18:35)

Plot summary
Directed by: Zack Snyder
Starring: Ben Affleck, Jeremy Irons, Diane Lane, Amy Adams, Jesse Eisenberg, Jeffrey Dean Morgan, Henry Cavill, Gal Gadot, Lauren Cohan
While the world still reels from the carnage caused at the end of Man of Steel, an increasingly vengeful Batman starts plotting Superman's downfall. Meanwhile Lex Luthor has his own ideas for how to control these powerful heroes by pitting them against each other, and Wonder Woman comes out of hiding after 100 years with an agenda of her own...
Chosen answer: Lex Luthor didn't find Superman's lair. Rather, he entered a crashed Kryptonian vessel that still had a functional computer database. Luthor used Zod's amputated fingertips to activate the database, which told him how to make the hybrid-clone monster, Doomsday.
