Millennium Entertainment has picked up U.S. rights to psychological thriller Dead Within from director Ben Wagner, his 3:41am shingle and Aengus James and Colin King Miller’s This Is Just a Test Productions. Pic follows a man and a woman who survive a deadly outbreak by isolating themselves in a cabin. When they run out of resources and are forced to open the door, they must confront the horrors that threaten them from outside and from within. Talk about method filmmaking: Stars Amy Cale Peterson (Wagner’s Southbounders) and Dean Chekvala (True Blood, People Like Us) were locked in a cabin throughout the production in what was filmed as an “immersive” shoot. Pic was scripted by Wagner and his actors with Matthew Bradford. Millennium is plotting a fall multi-platform release while SC Films will distribute internationally. ICM Partners negotiated the domestic and international deal on behalf of the filmmakers.
