The first full trailer for horror movie "The Quiet Ones" has been unleashed, featuring dark scenes that give loud scares. Sam Claflin is one of the students participating in a dangerous experiment to create a poltergeist not knowing that what they did would really attract the demonic spirit lurking around.
Inspired by true events, the scary film tells the story of an unorthodox professor who leads his best students off the grid to take part in the project. Based on the theory that paranormal activity is caused by human negative energy, they perform a series of tests on a young patient, pushing her to the edge of sanity.
Jared Harris plays the professor, while Olivia Cooke of "Bates Motel" portrays the young test subject. Coming from the producer of "Let Me In" and "The Woman in Black", the supernatural movie is set to haunt theaters in the U.S. on April 25.
