What happened to Emily?

Was Emily Rose possessed by demonic forces or was there a medical condition to explain her bizarre behaviour? Should the priest responsible for her soul be held accountable for her death or was an exorcism her only chance for survival? Based on incredible true events, The Exorcism Of Emily Rose tells a story that will chill you to the bone. A critical and box office hit, it is an edge-of-your-seat experience powered by terrific performances (Including Laura Linney from Mystic River and Tom Wilkinson from In The Bedroom) that is rightly hailed as one of the most chilling movies of the year (Paul Fischer, Moviehole).
