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 some years, so his current clothing would not reflect what he wore when captured, so he would not be considered a spy. After multiple escape attempts, his original uniform was probably ruined. POWs would have traded and swapped clothes. If prisoners died at the camp, their uniforms would be repurposed, regardless of branch or division. The Geneva Convention required that POWs receive shelter, food, clothing, medical care, etc. The Red Cross also delivered care packages to POW camps with food, miscellaneous apparel, and other essentials. Sweatshirts have existed since the 1920s and changed little. 1940s sweatshirts were similar to 1960s styles. Chino pants have been around since the late 19th century and were used for U.S. military uniforms.
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.
Other than the sweatshirt, Hilts is wearing military clothing - a leather bomber jacket and U.S. Air Force khaki trousers. So not "hipster" civilian clothing. The sweatshirt could just be something he had or acquired at another camp and appears to be his only shirt. He and two other POWs are the only Americans, so their uniforms are different. There's no way to say definitively what Hilts and other POWs would be allowed to wear. That was up to the camp commandant, who was shown as being rather disdainful about Hitler and his minions.
Factual error: Throughout the film, sea grape vines are seen all along the shore. Sea grapes do not grow in the Pacific, where the story takes place, only in the Caribbean where the film was made.
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: The sign outside the embassy reads "American Embassy", it should read "Embassy of the United States of America". North & South America are continents, not a country.
Factual error: The firefighters arrive at the gas station and proceed to spray water on the fire. You cannot put out a gasoline fire with water; it requires firefighting foam. Water would only spread the fire even more.
