Morten Tyldum, whose Norwegian thriller Headhunters became the most successful title in Norway box office history this year, has signed on to helm Vendome Pictures’ futuristic thriller What Happened To Monday?, which will be the director’s first English-language project. Headhunters, based on Jo Nesbo’s bestselling crime novel, garnered plenty of buzz when it played in Cannes this year, and WME signed Tyldum during the festival; he also is repped by Anonymous Content. (Magnolia Pictures already has North American rights to Headhunters and has set a spring release date in the U.S.) What Happened To Monday?, with a Black List script by Max Botkin, revolves around identical septuplet brothers who struggle to stay hidden in an overpopulated world where a one-child policy dictates that siblings are against the law. Raffaella De Laurentiis via Raffaella Productions developed the project; it will produce alongside Vendome CEO Philippe Rousselet. Vendome committed to finance the project in December.
