Spoilers So what is Lex Luthor ( Jesse Eisenberg ) going to do to get under Superman’s skin in Batman V Superman: Dawn Of Justice? We may have an answer. The Heroic Hollywood website is claiming that in some point in the movie Lex is going to kidnap Superman’s Mom, Martha Kent ( Diane Lane ). No more details are available but if you remember, Superman ( Henry Cavill ) was really pissed off when Zod messed with Martha in Man of Steel so I really hope Lex is ready for the repercussions. Batman V Superman: Dawn Of Justice opens in theaters on March 25. Here’s the plot Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’ most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
