You might recognize Lauren Cohan from her work on AMC's The Walking Dead, but in The Boy, she's dealing with a different kind of horror. Meet Brahms, a life-size doll that Greta (Cohan) has been hired to care for. Brahms represents a placeholder for his grieving parents, who lost the real boy of the same name 20 years prior. Greta quickly learns that her job comes with a strict set of rules, and breaking them means invoking terrifying consequences. Watch the clip above, then prepare yourself — The Boy hits theaters Jan. 22.
