Watch the Terrifying Full Trailer for 'The Conjuring 2'

While we caught a teaser for The Conjuring 2 earlier this year, Warner Brothers has unveiled the full-length trailer at WonderCon. Helmed by director James Wan, notable for directing Saw and Insidious, the story is based on two real-life paranormal investigators Ed and Lorraine Warren, played by Patrick Wilson and Vera Farmiga. The couple is brought to “England’s Amityville” to investigate malicious spirits terrorizing a local family. Notorious in history as a phenomenon of activities known as the Enfield Poltergeist which occurred in the late 1970s, Wan used real recorded footage from the Warrens to help craft the movie. The Conjuring 2 will be out in theaters starting June 10. Watch the main trailer above and be prepared to witness some truly horrifying moments.
