Like all fan's of stop-motion animation, my all time favorite fright flick is the Rankin/Bass 1965 classic "Mad Monster Party". The film was directed by Jules Bass and featured the voice talents of horror screen legend Boris Karloff as the fiendish bone-shivering Baron Von Frankenstein.
As a special treat, i've included two video clips for your viewing pleasure. The original trailer and from the way-out "The Mummy" sequence.
The above videos are in the Flash format, so make sure you have that enabled to view them.
