Wan's next film, "The Conjuring" (2013), centered on the real life exploits of husband and wife Ed and Lorraine Warren, a married couple that investigated paranormal events. The film focused on the couple's most famous case second to the Amityville haunting, in which they investigated a witch's curse on a Rhode Island family farm. In his second collaboration with the pair, Patrick Wilson starred in the film, with him and Vera Farmiga playing the husband and wife respectively. Filming commenced in North Carolina, United States, in late February 2012 and New Line Cinema, together with Warner Bros. Pictures, had initially slated the film for a release on 25 January 2013. A test screening of the film occurred in October 2012 at the New York Comic Con event, where it screened in the IGN Theater, and the audience feedback was overwhelmingly positive. At that stage, Wan had several more weeks before the film was completed. The film was released in July 2013 and was a critical and commercial success, grossing $319.5 million.
