Josh and Renai Lambert are a happily married couple who have recently moved into a new suburban home with their three young children. When their eldest son, Dalton, inexplicably falls into a coma, his condition coincides with the start of a series of disturbing events that defy any rational explanation. The ghostly goings on suggest a sinister supernatural presence is at work in the house, one that is intent on tearing the Lambert family apart. Forced to seek unconventional help to protect themselves and their children, Josh and Renai are awakened to the terrifying truth – it's not the house that's haunted.

Directed by James Wan, written by Leigh Whannell (together, the co-creators of the Saw movies) and produced by Oren Peli, Steven Schneider, and Jason Blum (the team responsible for Paranormal Activity), Insidious stars Patrick Wilson (Watchmen) and Rose Byrne (X-Men: First Class; Bridesmaids) in a chilling ghost story that has attracted some very positive reviews and was describe as being "so scary I was whimpering in sheer terror" by Robbie Collins in the News Of The World. Then again, are we taking anything printed in the News of the World seriously these days?

Co-starring Barbara Hershey (Black Swan, The Entity), Angus Sampson (Spirited), Lin Shaye (2001 Maniacs: Field Of Screams), Ty Simpkins (Revolutionary Road) and Andrew Astor (The Hangover), Insidious eschews the gross-out torture porn principles of many recent horror hits in favour of a return to the traditional and more subtle approach of playing on people's natural fears of the dark and the unknown.

Insidious (cert. 15) will be released on DVD (£15.99) and Blu-ray (£19.99) by Momentum Pictures on 12th September 2011.

Special Features will include:

• Horror 101: The Exclusive Seminar;
