I stumbled upon this stop motion comedy film from the 60's a few days ago, and have since watched it twice with my roommate. The visuals are amazing, and the quotes are priceless.
The voice behind the mad scientist is actually this guy:
Borris Karloff
Who more famously played...
Frankenstein's monster in Frankenstein (1931) and later, Bride of Frankenstein (1935).
The cast in Mad Monster Party include Allen Swift, Gale Garnett, Phyllis Diller and Ethel Ennis.
This spoof on horror themes is an amazing piece of art and has inspired my roommate and I to create our own stop motion film.
I'll let you know how it turns out :)
