Four score years less ten

This month there has been commemoration a'plenty of Germany's invasion of Poland seventy years ago. The US Holocaust Memorial Museum has a small, great, on-line exhibition, with photos, eye-witness testimonies and this 10-minute film by Julien Bryan, the last neutral reporter remaining in Poland on September 1, 1939. Reporting styles have changed so much - the opening music suggests we might be about to watch a Hollywood swashbuckler, and the narrative tone seems more removed, more fluid and in control than these days. But the story utterly belies the film's glossy production.

War footage is like a trillion permutations of same emotions: grief, terror, panic, pain, devastation. The loss in the faces of the survivors: you can change from B&W to colour, and change skin tones and languages and reporting styles, but that look of loss never changes.

Wonderful exhibition.
