Long before there was a HOTEL TRANSYLVANIA, there was MAD MONSTER PARTY?, a stop-motion animation musical comedy that's the perfect Halloween mood-setter. None other than the great Boris Karloff provides the voice for Dr. Frankenstein, a brilliant scientist and leader of the Worldwide Organization of Monsters. MAD MONSTER PARTY? enjoyed a brief theatrical run in the spring of 1967 -- great timing, right? -- and then turned up regularly on TV during the Halloween season throughout the 1970s. We're delighted to bring this loony cult classic back to the big screen.
