Oh! It's on Netflix!
I'd given up hope of ever seeing this. I like the book a lot. Ira Levin's such a good writer : )
You can't order it, but it's available for instant viewing through their site, if you're a member.
I'm excited (though I don't expect much. It doesn't have a great reputation. But it has to be better than the Sean Young version??)

EDIT: Oh no. Robert Wagner is such a crappy actor! Bluuugh.
