Horror movies deliberately violate those rules to make audiences squirm. The subject is placed at the rule-of-thirds lines, and there's more space in the direction the subject's facing, allowing what's called lead room. Movies traditionally go for a harmonious balance of positive and negative space. Narrator: See all this? That's called negative space: anything in the frame that's not the subject we're focusing on. Killer: Why don't you want to talk to me? These fleeting images and, more generally, the popular horror-movie style of quick-cutting between shots work to disorient you and make you question your own perception. The American remake of "The Ring" played a similar trick by inserting shots from the cursed videotape as flash frames in different scenes of the movie, but varying the frames in different versions of the film.

At the end of "Psycho," director Alfred Hitchcock placed this image of Mrs. So as each flash comes on screen, you get better at catching them, but you might also question whether you saw anything at all. That state of hypervigilance is right where horror movies want you. Research shows that people presented with threatening images, even briefly, become faster at identifying additional threats. But each image only lasts about an eighth of a second on screen, less than a blink of an eye. And this idea can apply to your visual senses, too.ĭid you catch that? This white face is one of several hidden shots of the demon in "The Exorcist." They are often referred to as subliminal images, which isn't really accurate, since we are able to consciously perceive them. These sounds operate at the outer edges of your hearing range to make you uncomfortable without you even knowing why. The BBC reported that 20 people at the Cannes Film Festival fainted during the film and needed medical attention.
