Recommendations for foreign and classic horror films?

Unlike the TV networks and cable channels, which tend to show only a week or so worth of good Halloween programming each year, I typically get in the mood where I watch several weeks worth of scary movies leading up to the holiday. So it looks like I’ll be starting to watch and review some horror movies sometime in the next couple of weeks. If anybody has any favorites of the genre they’d like to recommend, please feel free to pass them along. In keeping with the theme of the blog, I’ll be looking primarily at classic and/or foreign films (which are much better than contemporary Hollywood’s horror anyway).
