Goofs

As stated early in the film Franz Von Werra had a rigid forefinger on his right hand. However, at various stages during the film, Hardy Kruger had apparently forgotten this as he often bent that finger.

The bow of the ship that carries Von Werra to Canada is seen in close-up travelling symbolically right to left across the screen. Unfortunately, the original stock footage was of a bow travelling left to right and the editor just stuck a piece in, reversed. The numbers are mirrored.

When von Werra's Bf 109 is seen from a distance belly landing and coming to a stop, the propeller blades are clearly straight and undamaged. However, when he's seen climbing out of the cockpit seconds later in close up, the propeller blades are bent backwards at the tips.

When Von Werra crash lands, the cockpit canopy hood on the BF-109 mock-up is hinged on the port side and he exits on the starboard side. All actual BF-109's were the opposite; the cockpit canopy hood being hinged on the starboard side with the pilot entering/exiting on the port side.

On the train travelling across Canada, almost all the windows are covered with frost, but when it stops at a station, an exterior shot shows von Werra's is clear so that he can see out.

That's because he cleared the glass pane with his hand earlier.

When von Werra first reaches the snow-covered frozen river, there are already footprints in the snow.

At the very start of the movie, when Franz von Werra's damaged Bf 109 is descending for a belly landing, it is obvious that it is a scale model and not a real aeroplane.

When von Werra climbs out of the cockpit and sees the British troops running towards him, he immediately takes out all his maps and papers and sets fire to them, as he did in real life. However, when the British arrive and apprehend him, the papers (which are on the ground) show no sign of flames, and the British make no attempt to put out any fire or retrieve these potentially invaluable to intelligence documents.

When Von Werra ducks beside the ice-covered road to avoid a car, the car is an early 1950's Chrysler product, even though the story is set in the winter of 1940-41.

Whilst being driven to Station HQ at Hucknall, he passes two aircraft on the flight line. The first is a DHC-1 Chipmunk which first flew in 1949, nine years after the film is set and four years after the end of WWII.

At one point, as cover, Von Werra says he is part of the Royal Netherlands Air Force. While this would be correct for 1957 (the year the film was released), in 1941, it would be known as the Dutch Army Aviation Brigade.

Note: von Werra is in the German air force (Luftwaffe) and has escaped from a PoW camp, and is in a British shop still dressed in his flight suit but with the insignias etc hidden. He is then approached by a suspicious police officer (with the people in the shop listening) and as a bluff makes the false claim about being a Dutch pilot, and it works. Not being Dutch he simply might not have known the correct Dutch terms to use, but neither might any of those present in order to dispute it - since none of them are Dutch either.
