Noomi Rapace will star in the science-fiction thriller “Boy” with Danish helmer Jonas Arnby on board, Variety has learned. Lotus Entertainment is launching international sales for “Boy” at the Cannes Film Festival. Mattson Tomlin’s script for “Boy,” which was named to the 2015 Black List, centers on a teenage boy who is born with special abilities and spends his childhood switching names and cities to keep his identity hidden. When his conservative, suburban neighborhood discovers the risk he poses and blames him for a mass, tragic event, he and his mother must flee from the authorities who are looking to destroy him and seek the trust and support of an underground rebellion group. Clarance’s Motion Picture Capital will finance “Boy,” which will begin shooting in August.
