According to director Curtis Harrington, Hugh Griffith was an alcoholic and his wife accompanied him to the set each day to ensure that he did not drink.
According to Judy Cornwell's memoirs Shelley Winters discovered that Cornwell received good reviews in Wuthering Heights (1970) and demanded that Cornwell's role be cut to the bone.
Shelley Winters requested that her What's the Matter with Helen? (1971) director Curtis Harrington direct this film.
The original working title of the film was "Gingerbread House."
Director Curtis Harrington spoke warmly of working with Sir Ralph Richardson and Hugh Griffith on this film, but found Michael Gothard extremely difficult throughout and disparaged the actor in interviews about the film over 20 years later.
