The Atticus Institute

In the fall of 1976, a small psychology lab in Pennsylvania became the unwitting home to the only government-confirmed case of possession. The U.S. military assumed control of the lab under orders of national security and, soon after, implemented measures aimed at weaponizing the entity. The details of the inexplicable events that occurred are being made public after remaining classified for nearly forty years.

The Atticus Institute is a 2015 American independent found footage horror film written and directed by Chris Sparling (Writter: Buried [2010]) about a paranormal research institute, which becomes home to the only U.S. government confirmed case of possession.
