I found a place called Retrofilm that sells public domain films for use in production environments, but they don't list prices, usually a bad sign, in my experience. I also found a place selling NOTLD for $549 on DV, for the same purpose. I am struggling, because the film I working on has a character who watches a lot of TV and it is difficult to find anything for him to watch! Old horror movies would have been perfectm, but alas, there is always a catch. Thanks for the feedback, Spot...
