Peter Cushing is said to "act as himself" in this movie. Cushing's wife had died recently, and he was very depressed. His character is a widower who uses an ouija board to talk with his dead wife. The dead wife is said to have been called "Helen" - the name of Cushing's real wife.
"...And All Through the House" was remade by producer and director Robert Zemeckis as the second episode of Tales from the Crypt (1989).
The role of Mr. Grimsdyke was, at first, a tiny non-speaking role, but was greatly expanded when Peter Cushing took an interest in the role.
Stephen King and George A. Romero considered remaking this movie together. Their work together resulted in a completely separate, but similar movie, "Creepshow (1982)."
