Das unheimliche Erbe

I was 8 years old when this movie came out. We saw it as a family at the Baseline Drive-in. At the time it really scared me and my siblings. I just saw it recently on video and my impressions now are of course different. What I remember were the special glasses that you had to use to see or not to see the ghosts. William Castle at the time was the PT Barnum of horror movies and this was one of his latest gimmicks. Probably what I remember the most was finding for weeks afterward the discarded special glasses in our families orange grove since we lived about 1 mile from the drive-in and our road was on the way home for many people. My dad couldn't stand trash on our property and would pay each of us 5 cents for each one we brought to him.
