Boris Karloff - "We are playing a game with the audience and they are playing one with us... everyone likes to pretend there is something round the corner."

Christopher Lee - "The only time I really scared myself was in 'The Curse of Frankenstein' ...blood looks bloodier in black and white..."

Tony Tenser, the producer - "I am not happy about horror pictures which are too real... there is a limit to horror; if you are scared out of your wits it is painful..."

Sequences from silent horror classics of the 1920s and The Bodysnatchers, The Curse of Frankenstein, Theatre of Death, Comedy of Terrors.
