Just when you thought dolls couldn't get any creeper, out comes the first trailer for "The Boy," the new horror film starring "The Walking Dead" veteran Lauren Cohan.

In the film, directed by William Brent Bell, a young American woman named Greta (Cohan) takes a job as a nanny for an 8-year-old boy in a remote English village. But much to her surprise, she discovers the child is actually a life-size porcelain doll treated as human by her employers to help them cope with the death of their son two decades earlier. When Greta violates a strict list of rules, a series of disturbing and inexplicable events bring her worst fears to life, leading her to believe that the doll is alive.

Opening Jan. 22, "The Boy" also stars Jim Norton, Diana Hardcastle, Ben Robson, Rupert Evans, James Russell, Javier Botet.
