Andrew Graham-Dixon continues his exploration of German art by looking at the tumultuous 19th and early 20th centuries, and how artists were at the forefront of Germany's drive to become a single nation. Andrew travels to the north and the coastal town of Griefswald, the birthplace of Caspar David Friedrich, the most influential of the German Romantics, to discover how the Baltic coast impacted his mysterious paintings of the German landscape. He also visits Berlin and explores the art of the powerful Prussian state, which would spearhead the unification of Germany in 1871. The episode ends with the outbreak of World War I and the attempts of the artists Franz Marc and Otto Dix to rationalise the catastrophic experiences of the world's first technological war, a war driven by the Prussian innovations.

And epic film by Adam Curtis that explains why the big stories that politicians tell us have become so simplified that we can’t really see the world any longer. The narrative goes all over the world, America, Britain, Russia and Saudi Arabia, but the country at the heart of it is Afghanistan. Because Afghanistan is the place that has confronted our politicians with the terrible truth, that they cannot understand what is going on any longer". The coumentary reveals the forces that over the past thirty years rose up and undermined the confidence of politics to understand the world. And it shows the strange, dark role that Saudi Arabia has played in this. But Bitter Lake is also experimental. Curtis has taken the unedited rushes of everything that the BBC has ever shot in Afghanistan - and used them in new and radical ways. He has tried to build a different and more emotional way of depicting what really happened in Afghanistan. A counterpoint to the thin, narrow and increasingly destructive stories told by those in power today.
