The communist German Democratic Republic was established in the historic "Mitteldeutschland" ( Middle Germany ). Former German territories east of the Oder and Neisse rivers, mainly the Prussian provinces of Pomerania , East Prussia , West Prussia , Upper Silesia , Lower Silesia , the eastern Neumark of Brandenburg , and a small piece of Saxony were thus detached from Germany. To compensate Poland for the USSR's annexation of its eastern provinces, the Allies provisionally established Poland's post-war western border at the Oder–Neisse line at the Yalta Conference (1945). As a result, most of Germany's central territories became the Sowjetische Besatzungszone (SBZ, Soviet Occupation Zone). All other lands east of the Oder–Neisse line were put under Polish administration, with the exception of historic northern East Prussia , which went to the USSR. 
Road movies are common enough to warrant their own category. Whether the characters in a film are trying to get from point A to point B ( The Straight Story , Vanishing Point ), or simply enjoying the passing parade of life on the road ( Easy Rider , Il Sorpasso ), road movies have a special appeal. Although sometimes they end in tragedy, road movies are often about the experiential learning a journey can bring. They tend to be episodic, with the main characters encountering different people with different beliefs and values during their journeys.
