Paranormal Activity

Paranormal Activity is the most efficient horror film of the century and the efficiency is entirely in the frame.

The central device is a static night-vision shot of a bedroom with a timestamp running in the corner. Door on the left, bed in the middle, hallway at the back, stairs beyond. Peli establishes that geography in the first ten minutes and then uses it for ninety: every subsequent scare is a change to a space you already know by heart, and the film trusts you to notice a door that is three inches further open than it was. There is no score during the night footage. There is no cutting inside it. The audience does the work, and an audience doing the work is more frightened than an audience being told.

It is also the only found-footage film whose camera has a reason to exist. Micah is a day trader with money and no imagination who buys the camera as equipment, treats the haunting as a project, and keeps filming because he is winning an argument. The film's real subject is a man who will not stop poking something because stopping would mean his girlfriend was right.

The escalation is a ladder and every rung is small

Keys moving. A door. A sheet. A sound in the hallway with nothing in it. Talcum powder on the floor producing a non-human footprint. Katie standing by the bed for two hours, motionless, and then walking out into the garden. The film's most famous shot is a woman being dragged out of her own bed by her ankle, and it works because an hour of three-inch door movements has preceded it.

Where it is thin

The daytime scenes are badly acted and often badly written; Micah and Katie's arguments are improvised and repetitive. The psychic's visit is a lump of exposition in the middle of a film that otherwise explains nothing. And the film's one real cheat is the Ouija board, which exists to give Micah something idiotic to do.

For the film that invented this grammar, The Blair Witch Project; for the best found-footage film ever made, Lake Mungo; for the same demon-attached-to-a-person logic with a budget, Insidious.

The short answer: on the twenty-first night Katie gets out of bed, stands over Micah for two hours, goes downstairs and screams. Micah runs after her; there is a struggle out of frame; then something comes back up the stairs fast and throws his body directly into the camera, knocking it askew. Katie crawls into the shot on all fours, bloodied, sniffs Micah's corpse, raises her head and looks into the lens with a face that is not hers, and lunges. The film ends on a title card stating that Micah's body was found by police and that Katie's whereabouts remain unknown.

What is haunting Katie in Paranormal Activity?

A demon rather than a ghost, and the distinction is the film's only piece of cosmology. The psychic, Dr Fredrichs, states it plainly: a ghost is attached to a place and can sometimes be reasoned with; this is attached to a person, it has been with Katie since she was about eight, it followed her through a house fire and through moving home, and he cannot help her. It has no identity, no backstory and no grievance. It wants her.

Why does the demon follow Katie?

The film never says, and that is deliberate. Katie reports being visited as a child and that her sister Kristi saw it too; the family home burned down when she was thirteen; the entity has located her at every address since. Attachment to a bloodline rather than a building is the premise, and the refusal to supply a reason is what keeps the film from having a solution.

Why does the Ouija board matter?

Because it is the point at which Micah escalates deliberately. Fredrichs tells them explicitly not to communicate with it, and Micah buys a board anyway, leaves it out while they are gone, and comes home to footage of the planchette moving by itself and then the board catching fire. Nothing in the film is the same afterwards. The sequence is also the film's cleanest statement of its theme: the haunting gets worse every time the man insists on engaging with it.

What are the footprints in the talcum powder?

Micah spreads baby powder in the hallway to get an impression, and what it records is a trail of large, broadly non-human prints leading from the bedroom door down the hall and then simply stopping. The film shows them for about four seconds and never refers to them again. It is the only physical evidence the film produces of what the thing's body is like.

What are the alternate endings of Paranormal Activity?

The version Peli originally shot ends with Katie returning upstairs and cutting her own throat in front of the camera while Micah's body lies beside her, and the footage simply running out. A second ending has police entering the house and shooting her when she will not respond. The theatrical ending — the body thrown at the lens, the lunge, the title card — was reshot on Steven Spielberg's suggestion and is the reason the film became a franchise.

Scored against the published rubric, here is what the numbers mean.

Viscera 010 is near the floor — only 6 works score lower. One body, briefly, and some blood on a nightdress. There is no injury on screen at all until the last thirty seconds.

The threat at 014 is deep into the supernatural — only 8 works score lower. No human being in the film harms anybody, and the entity is explicitly not a dead person.

Pace 046 is just under the midpoint — 65 works are slower. The film is structured as twenty-one nights with long empty stretches, and the compression is all in the last twenty minutes.

Era bias 062 leans modern — 56 works score lower. Consumer digital video, a 2006 timestamp and a night-vision mode are the whole aesthetic.

Tone 020 is bleak — 54 works score lower. Both leads are gone, nothing was learned, and the entity is still at large.

Reality anchor 034 is grounded — 21 works score lower. One house, one geography, consistent rules, no sequence that cannot be read literally.

On jump scares: perhaps six, and all of them are built out of a door.
