Master of Horrors: Stuart Gordon: The Black Cat

This movie is about Edgar Allan Poe who is suffering from a severe case of writers block. He has an ill wife and an evil black cat named Pluto. 

It's a short show only 58 minutes. It looks like Master of Horrors was a Showtime series and this was one of the stories. I don't know. I never heard of Master of Horrors, will have to check that out.
