Out of all the war stories shot in the UK after 1945, this one stands apart because the hero is a German. It's a biopic of Franz von Werra, a Luftwaffe pilot who was gunned down over Kent during the Battle of Britain and became the only Nazi to escape from captivity. After many attempts, he finally got away while being transferred to a POW camp in Canada.
He claimed asylum in the neutral USA before making his own way back to Germany. The film overlooks his politics and mostly tells the events as a triumph of the spirit. Particularly in the final scenes as he drags himself across the frozen Canadian border to America. Hardy Krüger plays the flying ace with a blend of arrogance and single-minded courage.
Krüger manages to get us, if not actually on his side, at least amenable to his escape. So there is little friction; interrogation is so benign that it seems homeland security plans to keep the country safe with a mix of bureaucracy and self deprecating humour. Every time the prisoner breaks free he is thwarted by being given a form to fill in.
Von Werra isn't portrayed as a Good German, but the film does stress his audacity and resilience. Roy Ward Baker tells the story well, and keeps the narrative moving forward at pace in convincing locations with a good degree of realism. And there's a rare and interesting insight into British intelligence. Its a unique fifties British war film.
