The classic western "Rio Bravo" comes with an extra bonus DVD and this is one of three programs on that disk. It's enjoyable and talks about why this film is a classic. Mostly it consists of interviews (though only one of the stars, Angie Dickenson, was alive to be interviewed for the documentary) with various famous folks and film clips.
The biggest problem with the film--and the reason I didn't give it a higher score--is that the rest of the cast and the director had long since died. Without John Wayne, Dean Martin, Walter Brennan, Ricky Nelson and the director, Howard Hawks, the film does come up a bit short. But the ever-present Peter Bogdonovich (who seems to be in practically every similar film lately, as he's quite the film historian) and the rest try their best and give lots of good background information that make the wonderful film seem even more wonderful. If you love the film, then see this documentary to round out your viewing experience.
