Oren Peli wrote the script for Paranormal Activity and conceived the idea of creating a low-budget found-footage horror film.
The movie Paranormal Activity was filmed in Oren Peli's own home using a very low budget.
Paranormal Activity premiered at the Screamfest Horror Film Festival in Los Angeles to a positive reception.
DreamWorks and Paramount Pictures acquired rights to distribute Paranormal Activity after its festival success.
Following the success of Paranormal Activity, multiple sequels and spin-offs were announced and released, expanding the franchise.
Kristi moves in with her sister Katie and her boyfriend Micah, and they begin living together in Katie's new home.
Katie experiences strange noises and movements during the night, but Micah dismisses them as nothing significant.
To capture the source of the disturbances, Micah sets up a camera in their bedroom to record overnight activity.
The camera captures a mysterious figure and unexplained noises, confirming to Micah that a supernatural presence is in the house.
Katie is attacked by the supernatural entity during the night; physical marks are left on her body.
Micah and Katie visit a psychic who confirms a demonic presence and advises them on steps to protect themselves.
The psychic instructs them to set up salt traps and other protective measures around the house.
The supernatural events become increasingly aggressive despite protective measures.
The entity attacks Katie violently; Micah attempts to fight it but disappears mysteriously; the footage ends abruptly.
