The film is based on the acclaimed novel by Shirley Jackson.

The village below Blackwood House is called Shirleyville in homage to Shirley Jackson, author of the book upon which the film is based.

This was a passion project for screenwriter Mark Kruger, who initially began adapting the story into a screenplay in 2005.

Unhappy with previous adaptations of Shirley Jackson's work (including the critically panned 1999 film The Haunting (1999)), Jackson's eldest son Laurence Hyman worked closely with the production to insure the film kept to the book's spirit.

Taissa Farmiga and Alexandra Daddario both appeared in separate seasons of American Horror Story (2011).

Sebastian Stan and Crispin Glover also starred together in Hot Tub Time Machine (2010).
