10 More Insanely Accurate War Movie Details

10. Actual Blitz Survivors Can Be Seen - Battle Of Britain

Boasting a stacked cast, with the likes of Michael Cane, Laurence Olivier, Christopher Plummer and Ian McShane all popping up at various points, 1969's Battle of Britain focuses on the titular WWII events which saw the British protect their country from the Nazi Luftwaffe.

And during the Guy Hamilton-directed film, various civilians are seen sheltering from the Blitz in London Underground stations, with extras obviously being needed for these particular moments.

What you likely didn't realise is that many of the folks pretending to be Brits escaping the air raids here were actually real survivors who experienced these horrific bombings in reality. 

Unsurprisingly, the memories of those terrible attacks during the filming of these scenes led to some of said extras asking to be excused for a moment as they composed themselves (via Anglotopia). Even just pretending to relive these events must have been an ordeal, right?

It's a small detail, for sure, but one that makes these specific WWII London Underground shots feel that little more authentic once you know of them.
