The film's script was written by Sergio G. Snchez in 1996 and brought to the attention of Bayona in 2004. Bayona asked his long-time friend, director Guillermo del Toro, to help produce the film and to double its budget and filming time. The Orphanage is an international co-production between Spain and Mexico. Bayona wanted the film to capture the feel of 1970s Spanish cinema; he cast Geraldine Chaplin and Beln Rueda, who were later praised for their roles in the film.
