Hi. My mom wanted me to see if anyone could help her figure one out. She (in her late 70s) says she remembers seeing a movie on TV roughly in the 1954-1956 time frame that made a lasting impression on her. It had a mad scientist who was hoping to reanimate the dead, and he first successfully performed the experiment on a dog (German shepherd she thinks). It worked, but the dog came out aggressive and “weird”, and she said it could walk through walls which makes it sound to me more like a ghost than a revived corpse. She remembers it snarling and baring it’s teeth a lot.
She says he planned on then doing the same thing to a human but she doesn’t think he ever had a chance to do so. And she thinks the dog eventually killed the mad scientist.
Thanks in advance for any help!
