I Saw What You Did (And I Know Who You Are) (1965)

For years I wanted to see this movie but it was too expensive to buy, finally I was able to afford it, and today it's kind of corny, kind of campy, but I also think it's still very scary because it has an element of possibility to it. It definitely could happen that you prank call the wrong person at the worst time and then they get paranoid and are willing to kill whoever it takes to keep their dirty secret buried.

Has anybody seen it? Furthermore has anyone seen the remake with Shawnee Smith?
