What a fascinating little. A documentary, made by 'the british broadcasting service' that's being broadcast on an american tv channel, and which tells the history of america from the end of the civil war - which, in this world, the south won - to the present day. Things being rather different from the world we know as a result of the different history. The documentary uses everything you'd normally see in something like this, such as film clips, interviews, and historical material. Since this is a made up documentary for a film, they are all fake, but they're presented in a totally convincing manner. A lot of thought and work has gone into the production and the writing of this.
Being a documentary that's being shown on tv, it has lots of commerical breaks in the middle, complete with adverts and trailers for the most appalingly racist products and programmes you could possibly imagine. They provoke uneasy laughter. And that's the point. As the opening quote from george bernard shaw and the final scene will show you.
Possibly not to everyone's taste, but a fascinating vision and an excellent piece of cinema
