Trivia / The Two Faces of Dr. Jekyll

• Box Office Bomb: The film lost Hammer an estimated ₤30,000.
• Cast the Runner-Up:
  • Christopher Lee originally wanted to play the lead role(s).
  • In a 1967 interview, Paul Massie claimed that Hammer originally only wanted him for the role of the young-looking Hyde, but he argued for his playing the older-looking Jekyll as well.
• Uncredited Role: Lucy Griffiths as a tavern woman.
• What Could Have Been: Terence Fisher wanted Louis Jourdan to star. Laurence Harvey was Hammer's first choice for the starring role(s), and while he was keen to do it, his agent thought it would be a bad career move, so he ultimately turned it down.
