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 and a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform.
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.
Factual error: When the fleet of Glamcab Ford Cortinas drive out of their yard on the first day of business, some of the Cortinas are two door models, which wouldn't be legal for use as a taxi.

Factual error: Luki shows up late at night to retrieve his baseball cap from the house where Amelia is staying. He explains that the hat is very important to him because it was signed and given to him personally by Stan Musial.

Factual error: The weapons for this film, save for the American Krag-Jorgensen rifles, British Lee-Enfield MLE rifles, and German Mauser Gewehr 98 rifles, are completely wrong. The Russians, who had Mosin-Nagants, are portrayed with Mausers. The French are for the most part correctly poratrayed with Lebel Mle. 1886/93 rifles, but a few have Berthier rifles that weren't used until 1907. The Austro-Hungarians are portrayed with a mixture of Mausers and Berthiers when they would have had Mannlicher M88/90's or perhaps Mannlicher M95's. The Japanese are equipped with Mausers and would in reality have had Muratas. The Italians have a mix of Berthiers and Mausers, but would've used Vetterli-Vitali rifles. The Chinese Imperial troops and Boxers both have Gewehr 98 Mausers. Although they did indeed have Mausers, they had the far earlier Gewehr 71's and Gewehr 71/84's.
Factual error: Anthropology Professor Robert Orwell Sutwell explains that his black kimono was a gift from "the Tokyo Fire Department." The seven characters embroidered on the kimono are Chinese, not Japanese.
Factual error: All of the PT boats in this film are painted in the same Navy Gray used by larger warships of the US Navy in WWII. However, the real PT 109 and the other PTs in its squadron were painted green in order to better blend into their daytime anchorages or moorings near island jungles. The common green color scheme of this period was designated as "Design 5P" and incorporated Navy Green over a base coat of Ocean Green.Charles Austin Miller
