The American Revolution was at once a war for independence, a war of conquest, a civil war, and a world war, fought by neighbors on American farms and between global powers an ocean or more away. It impacted millions from Vermont’s Green Mountains to the swamps of South Carolina, from Indian Country to the Iberian Peninsula. In defeating the British Empire and giving birth to a new nation, the American Revolution turned the world upside-down. Thirteen colonies on the Atlantic Coast united in rebellion, won their independence, and established a republic that still endures. The American Revolution will present the story of the men and women of the Revolutionary generation, their humanity in victory and defeat, and the crisis that they lived through.

The two-part documentary “Automania” unfolds the history of the automobile as a relationship between man and machine. The car: drug, technical wonder, object of desire. Like hardly any other machine, the car is more than that. It is loved, cherished and cared for, protected and used for self-expression. At the same time, it is a sign of economic prosperity: whoever drives a (certain) car has made something of himself. And what applies individually also applies to societies: The car creates jobs and prosperity. But the dream relationship that lasted for 100 years has fallen into crisis. The films tell in an entertaining, moody and emotional way about the rise of the car to become an icon of the West and suggest future prospects. The films combine factual informations with nostalgically colourful memories of eyewitnesses. In addition, there are statements by experts as well as politicians and business representatives.
