"Rio Bravo" has a bonus DVD with three extras. One is a wonderful documentary about the director, Howard Hawkes. Another is a decent recent film about "Rio Bravo". The third is this film that celebrates a film set in the desert called "Old Tucson Studio"--where countless films were made over the years--including the feature. But the reason I think they included it with "Rio Bravo" is that this property had been used in the past but by 1958 it was all but abandoned for filming. Hawks' decision to use it and even expand it a bit led to the place being used in additional films--making it a renaissance of sorts for the desert locale. This is interesting, but the film seemed way too short. Since so many films were made there, I wanted to hear more about the films. But, other than "Rio Bravo" and a couple others, you really have no idea what else was made there. Not bad but a bit incomplete.
