THR reports that Netflix has officially inked a deal with Gaumont International Television for Eli Roth to direct and executive produce hour-long horror series Hemlock Grove. The project, which has cast Famke Janssen (X-Men) and Bill Skarsgard as its leads, is based on Brian McGreevy’s acclaimed gothic horror novel by the same name. The 13-episode first season will be instantly available in early 2013, the producers announced Wednesday. Hemlock Grove starts with the body of a young girl, mangled and murdered in the shadow of the former Godfrey steel mill. Some suspect an escapee from the White Tower, a biotech facility owned by the former steel magnates. Others believe the killer could be Peter, a 17-year-old Gypsy kid from the wrong side of the tracks, who tells his classmates he's a werewolf. Or it could be Roman (Skarsgard), the arrogant Godfrey scion, whose sister Shelley is disturbingly deformed and whose mother, Olivia (Janssen), the otherworldly beautiful and controlling grand dame of Hemlock Grove. As the crime goes unsolved and outlandish rumors mount, Peter and Roman decide to find the killer themselves, confronting unspeakable truths about themselves and Hemlock Grove as the mystery unfolds.
