The house that Mr. Keller lives in also served as Hill House, in the original version of Shirley Jackson's The Haunting (1963).

Also in the DVD commentary, John Hough states that Brian Clemens wrote the version of the screenplay he was most interested in directing, but Disney decided that this version was much too dark, and hired Rosemary Anne Sisson to lighten it up.

In the Anchor Bay DVD commentary, John Hough states that Bette Davis wanted to play both Mrs. Aylwood in the present and thirty years ago. The crew shot scenes with her wearing makeup to appear younger, but she was clearly older than the character the script called for. After the cast and crew saw the dailies, Hough told Davis in private that the scene just didn't work; no one would believe her as a woman in her forties. To her credit, Davis looked Hough in the eye and said, "You're Goddamned right."

When seen in the mirror maze Karen is wearing white tights. When she returns to the chapel they are gone.

When the mother gets scared about what is happening to her daughters and decides to flee, you can see a hose behind the car providing the rain just before they drive onto the bridge.

In the alternate ending, when the alien ascends with Jan in its arms, the wires used to cause ascension are clearly visible.

Tom Colley: Here. Hold. It won't hurt you none. They know when you try to help.

Jan Curtis: Mr. Keller I had to see you, it's about Karen Aylwood.

Jan Curtis: Mom said she'd only be a minute.
