Netflix doesn't have a good track record for certain titles. I think sometimes a more esoteric title may be damaged and they fail to replace it, or they decide they're just now going to stock certain titles. They don't seem to stock at all the MGM classic horror set with Mad Love, Mark of the Vampire, and Mask of Fu Manchu from a couple of years ago which seems like a pretty extreme oversight. I have noticed other examples recently. So, I'll be surprised if they do stock one of those to-order titles.
I've looked all over their site to see if there's a way to request a title but the only option seems if they have made an entry for the movie to click on the "save" button. Needless to say, this doesn't help if they haven't bothered to make a page for the movie you want them to stock.
