Curious to learn what it takes to create a thriller? Then you’re in luck…

Mexican filmmaker Guillero del Toro is giving the online community an inside look at Mama, the supernatural thriller he produced, through a special featurette.

Starring Jessica Chastain and Game Of Thrones’ Nikolaj Coster-Waldau, the film tells the haunting tale of two little girls who disappeared into the woods the day that their parents were killed.

They are rescued years later and taken in by family, but they apparently aren’t the only ones who make their way into the girls’ home.

“We are not only telling a story of a monster, we are telling the story of a very human emotion,” says del Toro.

Mama will open in theaters on Friday, January 18.
