Brian De Palma followed the huge success of Carrie with another slice of telekinetic horror, upping the ante by featuring more than one psychic.
John Cassavetes gives his most sinister performance since Rosemary's Baby as a man who kidnaps the telepathic son of his colleague (Kirk Douglas), aiming to turn him and similarly gifted individuals into human weapons. Meanwhile, Gillian (Amy Irving), is worried enough about the destructive potential of her own powers to agree to be institutionalised - but is the Paragon Institute all that it's cracked up to be?
De Palma pulls out all the stops with some spectacular set-pieces (including one that will put viewers off fairground rides for life), before a spectacularly explosive climax that unforgettably demonstrates why Gillian is so afraid of her powers. She can trigger nosebleeds without any effort, so how much damage can she do when she's actually trying to hurt someone?
