Sierra/Affinity and partner Incentive Filmed Entertainment Fund will finance and produce an untitled horror project from “The Devil Inside” filmmakers, with William Brent Bell directing from a script that he and Matthew Peterman wrote.The untitled pic will begin production in Romania in April, and is being produced by Peterman, Steven Schneider (“Paranormal Activity”) and Morris Paulson, a producer on “The Devil Inside.” Bell, Peterman, and Paulson will run the film through their production company Prototype and Sierra/Affinity will introduce the project to buyers at the European Film Market at the Berlin Film Festival next month. Details are under wraps other than the style of filmmaking the team brought to “The Devil Inside” will be applied to another horror mythology. “The Devil Inside,” released by Paramount Insurge, stunned Hollywood with its Jan. 6-8 opening weekend gross of $33.7 million that easily won the frame. Sierra/Affinity CEO Nick Meyer said, “From day one we have been huge fans of this filmmaking team and the way they have crafted a unique moviegoing experience with ‘The Devil Inside.’ These are filmmakers we know and trust and they bring an original voice and style to our next project that will once again introduce audiences to a new expectation of what one can define as a genre film.” Sierra/Affinity and Incentive are partners on “Parker,” starring Jason Statham and Jennifer Lopez, directed by Taylor Hackford from a screenplay written by John J. McLaughlin. Sierra/Affinity produced “Shark Night” while Incentive also financed the upcoming “Area 51″ written and directed by Oren Peli.
