 The opening title sequence is different on the Magnum version. The original   piano music has been replaced by an electronic synthesizer score, and the   title sequence consists only of "Lee Hessel presents" and "Vampyres" in red   lettering with a stylized V in the shape of two demons. The Anchor Bay   version uses the original credits, with plain blue lettering for "Vampyres   (c) Essay Films Ltd MCMLXXIV" followed by all the cast and technical   credits.
