Any of you ever saw "Encounter with the Unknown"? It really scared me as a child. They don't make films like this anymore. Four stories of the paranormal are presented with chilling commentaries, in a Twilight Zone format. In the first story, the spooky look in that lady's eyes as she put a curse on the three boys made me stay up many nights without sleeping!
Here is part one. The rest of the film is linked from there.
