Enough to say that it's Peter Jackson's least famous feature. It's a documentary about a another filmmaker. And therefore, it's probably mostly interesting to hardcore film freaks.
There's nothing stopping you checking IMDB or Wikipedia or anything else, but you'll be angry you did.
Me not telling you anything more, is for your own good.
NOTE: Co-director Costa Botes contacted me and asked that I remove the links for his movie. My intention with this site was always honoring the people who's work I admire, and though I originally complied and removed the links, after further debate it turned out he was a disgusting human being who supports even the most extreme measures, like shutting down the whole bitcoin currency, on the off chance it might mean more income for him. Therefore I cannot urge you strongly enough to go pirate all his films, copy them and give them out to all your friends, put them up on youtube, on google video and on facebook, make them as well spread as you possibly can, and make sure he never makes another dollar.
