I agree with KaeEll about Psycho, and I also have no idea about number 1. It seems to involve twins, but that didn't help me.
I'm sorry that Wait Until Dark wasn't on the list. I pretty much held my breath all the way through that movie, but I guess it may not quite fall into the category of "horror". More just suspense...
When a Stranger Calls scared the living daylights out of me, and my youngest nephew still can't even TALK about that movie! There was a remake a few years ago, but I doubt that it can match the original.

Did Nicholson make any other scary movies? And I wonder what ever happened to the woman that played his wife. I only remember her as Olive Oyl in the Popeye movie with "Mork". Oy, a senior's moment here, lol.
Uh, after looking on IMDb, it was Shelley Duvall and Robin Williams in Popeye. Duvall was the wife in The Shining, wasn't she?
