The Quiet Ones (2014)

A university student (Sam Claflin of The Hunger Games: Catching Fire) and some classmates are recruited to carry out a private experiment -- to create a poltergeist. Their subject: an alluring, but dangerously disturbed young woman (Olivia Cooke of Bates Motel). Their quest: to explore the dark energy that her damaged psyche might manifest. As the experiment unravels along with their sanity, the rogue PHD students, led by their determined professor (Jared Harris of Mad Men), are soon confronted with a terrifying reality: they have triggered an unspeakable force with a power beyond all explanation.
