The first official image for Insidious: Chapter 3 has just been released online, along with confirmation that the film will be a prequel. The official blurb states that Chapter 3 will be set before the haunting of the Lambert family (which was the subject of the first two films) but will shed more light on the nightmarish realm known as The Further.
Insidious: Chapter 3 will focus on a teenage girl and her family, who are being haunted by unknown entities. It will feature Lin Shaye, Angus Sampson, and Leigh Whannell reprising their roles from the previous two films.
Written and directed by Whannell and co-starring Dermot Mulroney and Stefanie Scott, Insidious: Chapter 3 will open in the US on 29 May 2015, with a UK date yet to be confirmed.
