What is this 70s horror movie?
I saw a movie when I was a kid,I believe it was still the 70's.The film had a mansion that
You could not drive away from, its drive way led back to the house as the man was trying to leave.It had a nun that would turn into a cat,someone chokes on a bone and it turns out that the bone he choked on was from a different animal than he was eating.someone dives into a swimming pool and can't get out as if there is glass on top of the pool.What is the name of this movie or am I just mixing up memories of different films?
