Kaya Scodelario stars as the main character, a troubled 17-year-old girl who babysits her new neighbor Linda's "baby," which is actually a very life-like doll. She goes along with the delusion while befriending Linda (Jessica Biel), who happens to be the spitting image of Emanuel's late mother.
Alfred Molina will play Emanuel's father, while Frances O'Connor will play her stepmother. Jimmi Simpson will play one of his co-workers at a medical supply store and Aneurin Barnard will play her love interest.
Production is expected to start at the end of January in Los Angeles.
