10 Possession Movies You Need To Watch If You Liked The Exorcist

10. The Atticus Institute

An independent and low budget horror movie, The Atticus Institute was released in 2015, written and directed by Chris Sparling and produced by Peter Safran. The film follows the style of a “true-life” documentary about a middle-aged woman – known as Judith Winstead – who is exhibiting frightening and paranormal behaviour that specialists are trying to get to the bottom of.

In the documentary-style film, central character Judith is recorded as exhibiting distressing and inexplicable feats, and it isn't too long before those studying her begin to believe she is under the influence of the demonic. Rya Khilstedt delivers a powerful and authentic performance in her role in The Atticus Institute, and the movie feels all-too real at times. A perfect picture for fans of the possession genre, it takes a somewhat unique slant, being set as it is in an institute in which the military and US government become involved.

Said to have been based on a true story (though to what degree is anyone's guess) the film certainly has all the hallmarks of a tense and creepy experience.
