After The Nanny (1965), Jimmy Sangster's wife Monica said she would leave the country if he ever worked with Bette Davis again. She duly left for their home in the south of France on the day Davis arrived for this shoot and remained there for the duration.
Shooting began on 3rd May 1967. After work on 8th May, Bette Davis made her complaint about Alvin Rakoff using television techniques to mark out the actors' moves and demanded his replacement. She then refused to turn up for work for the next two days, causing resentment among the cast who liked Rakoff. Davis cost the production six days of unusable footage and two days where production was at a standstill.
Original director, Alvin Rakoff was replaced by Roy Ward Baker when Bette Davis demanded the change.
The part of Mrs. Taggart was originally played on the London stage by Mona Washbourne. In a 2005 revival, Sheila Hancock, who plays the daughter-in-law in this film, played Mrs. Taggart.
According to Hammer historian Marcus Hearn, Bette Davis again renewed her unsuccessful campaign to seduce Jimmy Sangster.
