Warner Bros. has released the first full-length trailer for director James Wan’s (Saw, Insidious) upcoming horror film The Conjuring.  The first trailer for the film was a genuinely terrifying clip that showcased the kinds of scares Wan has crafted for this latest horror pic, and this new full trailer is no less terrifying.  The film is based on the story of the Perron family who inhabited a haunted Rhode Island farmhouse in the 1970s.  Lili Taylor and Ron Livingston play the Perrons, and Vera Farmiga and Patrick Wilson play a husband and wife team of psychic investigators who encounter the most horrifying case of their career.  Wan recently told the audience at WonderCon that the film received an R-rating simply for being “too scary,” and I’m now fairly certain that I’ll be watching this one through covered eyes this summer.

Here’s the official synopsis for The Conjuring:

Before there was Amityville, there was Harrisville. Based on a true story, “The Conjuring” tells the horrifying tale of how world-renowned paranormal investigators Ed and Lorraine Warren were called upon to help a family terrorized by a dark presence in a secluded farmhouse. Forced to confront a powerful demonic entity, the Warrens find themselves caught in the most terrifying case of their lives.
