I do not intend to discuss these in detail, except to say that it seems almost like a rarity if there aren't many. At the other end of the spectrum, we have the recent The Wizard of Oz , which even in its expensive edition, contains enough features to start you on a career as a film historian. By contrast, it is historically fascinating to learn that all of the effects in The Exorcist were achieved by mechanical means, not digital ones. In the following lists, I have included movies regardless of their intrinsic merits that could form the basis of a collection that will show off the potential of the medium. I have adopted a series of initials when I want to underline some of a given disc's stronger points.
C stands for content and denotes a movie of unusual merit.
V stands for the visual, as S stands for unusually good sound. DQ indicates a disc of demonstration quality.
