Genre label IFC Midnight has acquired U.S. rights to Inner Demons, a possession tale about an Intervention-style reality TV crew filming a 16-year-old (Lara Vosburgh) fighting addiction who actually might be possessed by a demon. Director Seth Grossman has some expertise in the area; he was a producer on A&E’s popular series Intervention. Morgan McClellan, Colleen McGrann, Kate Whitney and Brian Flaherty also star in the pic scripted by Glenn Gers and produced by Robin Schorr, which premiered at the LA Film Festival in June. Arianna Bocco and Sean Berney negotiated the deal for Sundance Selects/IFC Films with Josh Braun of Submarine and Linda Lichter of Lichter Grossman Nichols Adler and Feldman on behalf of the filmmakers.
