We have the documentary basically done at this point (as evidenced by my three successive very late nights leading up to today), and will spend this coming week making final changes and getting everything ready for an official DVD release.
The final DVD will have a slightly longer cut of the documentary, more polished graphics, several very good deleted scenes, a stills-based series of interesting facts about wardens that just wouldn't fit into the documentary (James is doing the text for that), and possibly some other goodies.
