Scary but not bloody

Halloween is just around the corner. I am interested to see if we get and trick-or-treaters this year, since I never have before. This is our first year spending the holiday in a house instead of an apartment, so I think we have a chance. We will probably pick up a bag of candy this weekend, and we just need to make sure that we get something that we will be willing to eat if no one shows up.

Something else that seems to happen to us this time of year is a desire to watch scary movies. We watch a lot of movies these days, and although I watched a lot of slasher films back in my younger days, we tend to stay away from anything that would be considered scary. We watch a lot of documentaries (including the entire UP series in the last month) and smaller independent films. Once a year, though, we seem to get taken over by the Halloween vibe. However, we don't really want to watch anything that is particularly bloody or slasher-like. Last night we went to the locally owned rental store nearby and spent a while looking through the 'suspense' section. We left with 'Rear Window', which has always been an excellent movie, but hardly scary or Halloweenish (though, if you ever watch it on DVD make sure to check out the theatrical preview in the bonus section. I don't think I have ever seen a preview where the actor, in character, addressed the audience), and 'The Salton Sea', which neither of us really know anything about, but looked interesting.

So, does anyone have any suggestions of good scary, but not bloody, movies?
