Activity Definition and 193 Threads

Paranormal Activity is a 2007 American 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 in their home. They then set up a camera to document what is haunting them. The film utilizes found-footage conventions that were mirrored in the later films of the series.
Originally developed as an independent feature and given film festival screenings in 2007, the film was shot for $15,000. It was then acquired by Paramount Pictures and modified, 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 $193 million. Paramount/DreamWorks acquired the U.S. rights for $350,000. It is the most profitable film ever made, based on return on investment, although such figures are difficult to verify independently as this is likely to exclude marketing costs.The film is the first (chronologically, the third) entry in the Paranormal Activity film series. A parallel sequel and prequel, Paranormal Activity 2, was released in 2010. The success of the first two films would spawn additional films in the series: the prequel Paranormal Activity 3 in 2011, and Paranormal Activity 4 (the sequel to the second installment) in 2012. The fifth installment, The Marked Ones, was released in 2014, and the sixth installment, The Ghost Dimension, was released in 2015.
On June 19, 2019, Paramount announced that a seventh installment is in development and would be released on March 19, 2021. However, in August 2020, it was announced it would be delayed to March 4, 2022 due to the COVID-19 pandemic.
