Family can be such a bitch, right? Lucas (Nikolaj Coster-Waldau) and his girlfriend, Annabel (Jessica Chastain) searched and searched for his young nieces after they mysteriously went missing in the woods when their parents died. Finally the young girls turn up, Lucas and Annabel take them home, and all hell breaks loose.
Chastain is front and center in the international trailer for Mama, directed by Andres Muschietti. It features new footage and makes it abundantly clear that raising someone else's children is no easy task, especially not when they're haunted by a ghost who insists on visiting rights.
Guillermo Del Toro served as mentor and executive producer. The film is due out in the U.S. on January 18, 2013.
