Jessica Chastain and the Cast of 'Mama'

Oscar nominee Jessica Chastain and executive producer Guillermo del Toro on the making of their new thriller Mama. 

"It was a big challenge to convince her agents and managers because everyone knew she was great actress and they didn't want her going to do a  thriller or genre piece and fortunately for me we had Pans Labyrinth and The Orphanage and other pieces I've produced or directed, proved to them that we were going to do this the right way" Guillermo added about landing Jessica in the lead role.
