The duo wrote a traditional script, however they eventually, according to Peterman "got frustrated with that process" so they rewrote to a mockumentary style following a suggestion from producer Morris Paulson. Principal photography began in 2010 in several locations, including Bucharest (Romania), Rome (Italy) and Vatican City. The film is of the "found footage" genre, and so is shot in documentary style despite being fictional. Lorenzo di Bonaventura and Steven Schneider took the movie to Paramount Pictures, who ultimately produced it through their low-budget company Insurge Pictures, who acquired the film as their first release hoping it would replicate the success of Paranormal Activity.
