This sounds almost as stupid as Death Bed: The Bed That Eats (although to be fair I haven't seen either film).

I heard about this when it came out. Never bothered to see it. The premise strikes me as a little too highly sexualized to strike me as all that scary.
As for the scariest mover ever I think I'll give it to "The Shining."

One of these, of course. It's so hard to pick just one, though.

Do you two mean El Orfanato (the spanish movie)? I didn't like it at all. Also, the scarriest movie ever is John Carpenter's In the mouth of madness.
