Nightmare Fuel / Zero Day

• The movie's slow burn lead up to the massacre as Andre and Cal make their tapes and plan out their crime is liable to leave many viewers with a sense of impending dread as events inch closer and closer to the Foregone Conclusion.
  • The parts where Andre's cousin Chris is convinced to take them out for target practice carry a particularly creepy air as only the audience and the future gunmen are privy to what some of those guns are going to be used for. The viewer is practically invited to imagine the wounds of the future victims as various targets are hit and the ballistics damage inflicted to them are shown off. Not helping is how enthusiastic Andre and Cal appear to be at the prospect of "killing" the toys and their other unsettling comments.
  • The entire sequence where Andre talks about the guns in his home, bragging about how he doesn't need to draw attention to himself buying an arsenal because he knows where the key to his father's gun safe is. He then shows the audience how to make the shotgun more concealable by attaching a shorter stock to it and demonstrates how quickly he can perform this, closing with "54 seconds is all I need to be able to hide this sucker and come after you."
  • The scene where Andre and Cal are making pipe bombs and wondering what kind of injuries they'll produce. On the topic of shrapnel, Cal notes they filled their bombs with screws and lists several other options to use to cause injuries.
• The footage captured by the high school security cameras.
  • The beginning of the shooting shows a crowd of students running down a hall, only to bolt in the other direction when Andre and Cal show up in the direction they're headed in. Andre then picks up the cell phone of a recently deceased victim to taunt the 911 operator and scream into the receiver.
  • Upon entering the library, Cal shouts "HEY EVERYBODY!", showing off his inner anger and sadism as he revels in his victim's terror in a major break from the usually kind and polite person shown prior to the killings.
  • The boys take their time killing people, casually menacingly them while they scream loudly. Andre briefly takes a seat in front of a hysterical girl to just laugh at her before moving on. Cal at one point screams at the same girl to shut up as she bleeds out from a bullet wound, eventually killing her after he gets fed up with her cries.
  • Gregg begs Andre to spare him, even calling him sir, much to Andre's amusement. After deeming him too pathetic to murder, Andre decides to let him live. Just as it seems Gregg is going to make it, Cal shoots him instead.
  • Finally, there's the suicide of the pair. After having a brief discussion on whether to fight the police to the death, Cal convinces Andre to take part in a Suicide Pact. After a false starts where Andre briefly loses his nerve and gets talked back into it, they decide to count to three before shooting themselves. After a second attempt ends in hesitation again, the two ultimately go through with it. All throughout this, the 911 operator still listening in tries to get their attention and talk them out of it only to be ignored and momentarily goes quiet after hearing the last gunshots.
• The very premise of the movie. Two normal, teenage boys decide to go on a shooting spree in their local high school, killing without any mercy. The worst part is how Truth in Television it is.
  • The creepy part isn't the usual media-based mentality that the shooters were unstable or violent; Cal and Andre are shown to be normal and decent kids, who decided to do a school shooting because they wanted to. That makes the entire premise more creepy and the duo's brutal violence all the more inexplicable.
