Paranormal Activity

Paranormal Activity is a 2007 American found footage supernatural horror film produced, written, directed, photographed, and edited by Oren Peli. It centers on a young couple (Katie Featherston and Micah Sloat) who are haunted by a supernatural presence inside their home. They then set up a camera to document what is haunting them.

Originally developed by Peli as an independent feature and given film festival screenings in 2007, the film was shot for $15,000. It was then acquired by DreamWorks Pictures, then a Paramount Pictures subsidiary, who modified the film, particularly with a new ending that cost an additional $200,000. It was given a limited U.S. release on September 25, 2009, and then a nationwide release on October 16, 2009. The film earned nearly $108 million at the U.S. box office and a further $85 million internationally for a worldwide total of $194 million. Paramount would then solely acquire the U.S. rights for $350,000. It is often cited as the most profitable film ever made, based on proportionate return on investment, although such figures are difficult to verify independently as this is likely to exclude marketing costs.
