Is Paris Burning? (1966)

During the 1944 liberation of France the allies storm the city of Paris while the Nazis try to burn it under instructions from Adolf Hitler to obliterate the city. 

The film is understandably somewhat confusing and rambling, but star cameos add interest.

Adapted from the best-seller by Larry Collins and Dominique Lapierre, with the adaptation performed by Gore Vidal and Francis Ford Coppola (amongst others).
