Based on the real life case of family annihilator John List who was the inspiration for the 1987 film 'The Stepfather'.
The film entered the Official UK DVD chart at #19, the second highest opening for a North Bank Entertainment title.
The quote by John List as Bob Clark is from EPHESIANS 4 : 32, not 4 : 31, and in the King James Bible, both verses appear as : "Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you."
