Not only does Jared Harris star, but this is an official Hammer Films release. The Quiet Ones opens theatrically April 25th.
Inspired by true events, The Quiet Ones tells the story of an unorthodox professor (Jared Harris) who uses controversial methods and leads his best students off the grid to take part in a dangerous experiment: to create a poltergeist. Based on the theory that paranormal activity is caused by human negative energy, the rogue scientists perform a series of tests on a young patient, pushing her to the edge of sanity. As frightening occurrences begin to take place with shocking and gruesome consequences, the group quickly realizes they have triggered a force more terrifying and evil than they ever could have imagined.
