My dad keeps talking about this movie that he can’t remember the name of. It would be from the 1960’s or 1970’s, he thinks around 73-74.
The main character is a doctor, and it’s almost a puppeteer-style movie. The doctor makes these little creatures, and puts organs of his patients inside the creatures. The little creatures then go and kill people for the doctor.
One specific scene he remembers is where the doctor sews an organ into one of the creatures and sends it up a dumbwaiter. The little creature gets out in an office and is about to stab the person in there, but the person sees and squishes it before it can stab him. The creature’s/organ blood goes everywhere.
Can anyone please help?!?
