History is often hijacked for propaganda purposes - everyone does it and did it from Birth of a Nation through to Henry V and the Alamo - one of the themes Germany used in the 20s and 30s was the saga of movies about Frederick the Great - the Fridericus Rex films. Starring Otto Gebühr they span the silent era from 1920 until this one, the final film, a remake Der Groesse Konig in 1942. It depicts the battle of Kunersdorf - a disaster for the Prussians against the Austrians and Russians. Anyway watch the clip - it conjures up an 18th century battle reasonably well and fairly spectacularly too. Hitler associated himself with Frederick the Great and watched these movies for relaxation after a hard day's trying to rule the world.
