Zack Snyder reveals a new deleted scene for Batman Vs. Superman, which I guess sort of explains why the Man of Steel didn't find his mother when Lex Luthor kidnapped her.
Honestly, it's a pretty weak argument from Snyder as we already know Superman could find Lois Lane half way around the world when she was held hostage by terrorists in Africa.
Here's what Snyder revealed to IGN:
“I think all the way – to me, from Metropolis to Smallville is probably just on the edge of his range of hearing” he explained. “Also the clutter of the city makes it difficult as well."
"We had a scene that we cut from the movie where he tries to look for her when he finds out that Lex has got her," Snyder continued. "It was a slightly dark scene that we cut out because it sort of represented this dark side. Because when he was looking for his mom he heard all the cries of all the potential crimes going on in the city, you know when you look.
“I kind of like the idea that he’s taught himself not to look because if he looks it’s just neverending, right? You have to know when, as Superman, when to intervene and when not to. Or not when not to, you can’t be everywhere at once, literally you can’t be everywhere at once, so he has to be really selective in a weird way about where he chooses to interfere.”
As noted, it's unknown if the deleted scene will make its way in to the Batman Vs. Superman director's cut.
"Batman v Superman: Dawn of Justice" is directed by Zack Snyder starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves.
Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s 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.
