Since this film taks about the assassinated US President, you know that you're in for an incredibly dark documentary.
- The Paranoia Fuel-based terror in the film is when Garrison is reading the Warren Report and listening to Lee Bower's testimony, especially with the Scare Chord shot of Bower's dead body.
- The infamous Zapruder film, the home movie filmed by Abraham Zapruder that managed to capture the moment when Kennedy was fatally shot, is shown in this movie. And this isn't actually a recreation of the Zapruder film for the movie. This is the REAL-LIFE footage, with the real-life President Kennedy getting murdered. Anyone not familiar with the footage, or who hasn't seen it, might well find the actual headshot very disturbing. You literally (and repeatedly, in slow motion), see part of his head being blown off. This is perhaps the most Realism-Induced Horror in the film history.
- X's summation of how big the conspiracy is. Even with all the holes in real life that have been pointed out, in the context of the movie it's terrifying the kind of power such a small group could hold over the actions of a nation, even starting the Vietnam War to achieve their unknown goals.

David Ferrie: Oh man, why don't you fuckin' stop it? Shit, this is too fuckin' big for you, you know that? Who did the president, who killed Kennedy, fuck man! It's a mystery! It's a mystery wrapped in a riddle inside an enigma! THE FUCKIN' SHOOTERS DON'T EVEN KNOW! - The autopsy scene. Not only are the visuals of president Kennedys dead, mangled body unpleasant to watch, the doctors who are struggling to do their jobs while obstructive bureaucrats are doing everything in their power to hinder and complicate the autopsy just lends to the overall surreal and oppressive nature of the scene.
