Mama is a 2013 Spanish-Canadian horror film co-written and directed by Andrés Muschietti and starring Jessica Chastain and Nikolaj Coster-Waldau. The film, produced by J. Miles Dale and Bárbara Muschietti, with Guillermo del Toro serving as executive producer, is based on Muschietti's Mamá ("Mom"), a 2008 Spanish language short film of the same name that captured del Toro's attention. The film deals with the story of two young girls abandoned in a forest cabin, fostered by an unknown entity that they fondly call Mama, which eventually follows them to their new suburban home after their uncle retrieves them. Originally set for an October 2012 release, it was released in theaters on 18 January 2013.
