"Batman v Superman: Dawn of Justice" was a dark film, but director Zack Snyder feels it could have been even darker. During an interview with IGN, he described a scene he cut because he felt it represented the darker side of the film.
"We had a scene that we cut from the movie where [Superman] tries to look for [his mother] when he finds out that Lex has got her," he explained. "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."
