I bought a used copy at ........ today and it only had one disc. That disc had a very small #1 on it. There are some extras on it but not what I espected. Should it be a two disc set or is that all there is. It is supposed to be the Collector' Edition.

There have been five versions (http://www.dvdcompare.net/comparisons/film.php?fid=422) of MEN IN BLACK released. The Collectors Edition was a two disc set.
