As one recent example, a movie with Giovanni Ribisi that was made about ten years ago (forget the title, something about buying a dog). Known actor, not terribly old movie, not available anywhere but a used DVD from Amazon. I’m not a cinephile into obscurity, but at least once or twice a year I’ll be unable to find a movie with known actor (Ribisi, Robin Wright, as two that come to mid) that, when I finally find a DVD or torrent, wasn’t a bad movie that deserves to be buried in a stack of $4 used DVDs.
