Older movie
I'm trying to think of a movie that I saw at the Fairborn Theater either late 60's or early 70's. It was about a man who died and left his inheritance to greedy family members. They had to come to his mansion for the reading of the will. They all knew their Uncle had a wall safe hidden in the house. They all died one by one trying to find the safe. One died when acid was put in her nightly face cream, one died in a shower that had acid instead of water. The last person finds the safe, only to find it's very deep in the wall, and has to crawl partly in then is beheaded. The uncle was really alive watching his greedy relatives.
ANYBODY REMEMBER THIS MOVIE?? It's driving me crazy!

Could this be it?
The Cat and the Canary 1927: Movie and film review from Answers.com

I remember an episode of the Twilight Zone that's kind of similar.. IDK though sounds great!

Not Cat and the Canary. I looked it up. That's an older movie. This was made in the late 60's or early 70's.
