I saw this fun little (60 minutes give or take) documentary at South by Southwest 2004 and the audience I was with ate it up. Footage of a rattlesnake roundup and show in Oklahoma is interspersed with interviews of some of the participants as well as an actual Herpetologist who, of course contradicts about half of everything the "snake handlers" say. There's not really a whole lot more to it, but some of the characters presented here are in the "too weird to be made-up vein" that makes these kinds of docs so fun to watch. It's not for the squeamish; I will say that. There are several shots of snake butchering that will make a lot of people turn away. Anyway, it's worth a viewing if you get a chance. Their website says it's available on DVD for $12, but doesn't have an order form, so I'm not sure if that's accurate or not.
