Warner Bros. and New Line Cinema have released a full-length trailer for SAW and Insidious director James Wan’s The Conjuring, starring Patrick Wilson and Vera Farmiga as real-life married demonologists Ed and Lorraine Warren, best known for their work on the infamous Amityville Horror case of 1975.

Written by Chad and Carey Hayes (Whiteout), the story—based on true events—follows the horrifying ordeal faced by the Perron family in 1970 after moving into a haunted Rhode Island farmhouse. The film co-stars Ron Livingston (Office Space) and Lili Taylor (The Haunting) as the Perrons.

The Conjuring opens in theaters on July 19.
