Factual error: Why is Hilts not wearing a uniform? A serving officer captured behind enemy lines in civilian clothing risked being shot as a spy. If a prisoner's uniform was too worn or damaged to wear, it was routine for the German authorities to replace it - a P.O.W. in civilian clothes is an obvious escape risk. He is wearing a pair of tan chinos, a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform. He is also wearing Army Type III Service boots - something that would never have been issued to a fighter pilot.
Suggested correction: Hilts was a POW for a few years before being transferred to this camp. His current clothing likely changed from when he was originally captured in his uniform, so he would not have been considered a spy. After multiple escape attempts, his uniform could have been ruined. The Geneva Convention required that POWs receive shelter, food, clothing, medical care, etc. The Red Cross delivered care packages to POW camps containing food, miscellaneous apparel, and other essentials. Sweatshirts have existed since the 1920s and changed little. Also, chino pants have been around since the late 19th century. Hilts was an U.S. Air Force pilot, and light-colored khaki trousers (similar to chinos) were standard-issue uniform for some U.S. military branches, along with leather bomber jackets for Air Force pilots.
And none of them would have been available to a prisoner in a German POW camp in Poland in the mid 1940s. Not one single item of hipster fashion would have found its way into the camp. Even if it did, do you really think the German authorities would allow a prisoner to lounge about in civilian clothing? Talk about an escape risk.
The camp was in Germany, not Poland. Other than the sweatshirt, Hilts appears to wear military clothing - a leather bomber's jacket with military sleeve insignia, and U.S. Air Force khaki trousers. So not "hipster" '60s civilian clothing. The sweatshirt could be military appropriate (even issued) and something Hilts acquired at a different camp. He arrived with a small duffel bag that presumably had some misc clothing. He and two other POWs are the only Americans and have different uniforms. The current camp commandant, who apparently disdained Hitler and his Nazi minions, would decide what POWs could wear.
Factual error: In the scene where James Bond is being given his "gadgets", Q points out that his rifle is an "AR-7 in .25 caliber". The AR-7 is a real rifle, but is only available in .22 Long Rifle caliber. Due to numerous design features, especially the screw-off barrel, it can't be made to fire a .25 caliber cartridge of any type. (00:22:05)
Factual error: When Ding Bell is passing the truck, his car downshifts then shifts into a higher gear after passing the truck. Ding never took his hands off the wheel. This is in a VW Bug. These all had manual transmissions when this was filmed. He would have had to manually shift the gears to have the car change gears, but he kept steering with two hands on the wheel.
