This trailer for the spooky wolf child flick Mama definitely comes out swinging. Watch as the couple Annabel (Jessica Chastain) and Lucas (Nikolaj Coster-Waldau from Game of Thrones) take in their newly discovered nieces — after they've been left alone in the forest for five years. However, the girls (who both take on the role of squirrel children beautifully) may not have been really that alone in the wilderness. And whatever was keeping them company in the wild, has come back with them to their new home.

Produced by Guillermo del Toro and directed Andres Muschietti, Mama will hit theaters on January 18th, 2013.
