If you are in the UK, tonight on BBC2 at 9:30pm, you can watch Peter Jackson's "They Shall Not Grow Old".
'Employing state-of-the-art technology to transform audio and moving image archive footage more than a century old, Peter Jackson brings to life the people who can best tell the story of World War I: the men who were there.'
They even went to far as to hire lip-readers, so as to create a "script", and then had voice actors voice the words recorded on the silent films.
My Father was a Prisoner of War in World War II. Captured in North Africa, taken to Stalag 4c, in the Czech Republic. A Driver in the Royal Army Service Corps, he was a part of the Cyprus Regiment.
He never spoke much of his service, other than to sometimes say he'd eaten grass through hunger, and had seen comrades blown up.
It was shortly after he passed in 2008, that I learnt he actually escaped from the Stalag, some 3 days before the end of the War. Lost, the Red Army found him & told him.
