I stumbled upon this mockumentary on Youtube around a year ago, and it honestly never gets old watching it. It was released on DVD only, but it's pretty good for a DVD-only release. The movie presents itself as a British documentary about the history of the victorious Confederate States of America and their history from the Civil War to present day. It's worth a watch, especially if you like alternate history that is a bit out there, here's the first part on Youtube:
Is there anything about vampires taking over the world? Because if there isn't it's not very realistic.
Well, they do conquer the entire Western Hemisphere except for Canada.
I've posted here to remind me to get to watching this video. I'm very interested in alternate history and love mockumentaries as well. I'll tell you what I think once I've watched it.
