Yep. I know Zachary, and own the DVD, and it's pretty great. But it's exactly what you would expect it to be: a guy adapting the novel (not the movie) First Blood into a film, by himself, in his apartment. It's worth watching at least once.
If you're at all interested in background, it's actually a companion to his one-man show with Nature Theater of Oklahoma, Rambo Solo, also worth seeing if you ever get the chance.
