The debut feature from writer-director Glenn Standring, The Irrefutable Truth about Demons sees anthropologist Harry Ballard (Karl Urban) threatened by a sinister cult. With the help of beautifully bizarre Bennie (Katie Wolfe) he endures a terrifying night as his friends are killed by demons. Or are they? Hounded by the memory of his dead brother, Harry suffers beatings, heart surgery and assault by cockroaches. Variety said Demons "conjures a creepy, brooding atmosphere and enough thrills to keep young horror enthusiasts glued." The film sold to more than 50 countries.
