This movie is in the SCI-FI CLASSICS 50 MOVIE PACK.
The damned thing is only a little over an hour long, but it's so boring that it took me 3 separate viewings to get through the damned thing.
A rich old woman hires a mad scientist to put her brain into a younger, more beautiful body. At one point, the scientist transplants a cat's brain into a woman and she walks around meowing and hissing and clawing at people. The "twist" ending is laughable. Run away! Run away!
This is a good bad one for sure. Bought and watched it a couple years ago. It's a.k.a. MONSTROSITY.

This is not to be confused with Herman Cohen's 50's classic CREATURE WITH THE ATOM BRAIN and Andy Milligan's final film MONSTOSITY.
