Factual error: There are a number of computers and gadgets shown which were not introduced in early 2002, i.e. HP LaserJet 1320 Printer at Asra's place, HP Color LaserJet shown at the consulate, Acer Notebook used in investigation, and the Nokia 1100 cellphone used by Captain.
Factual error: The daylight air-raid on the Norwegian Heavy Water plant in 1942 was done by Boeing B17G bombers, with the distinctive chin gun turrets. These planes did not come into service until 1944, when they were introduced to counter the head-on attacks by German fighters.
Factual error: In the beginning of the film, a variety of different suitors are presented to Elizabeth. Amongst them are Eric XIV of Sweden, reportedly "still madly in love [with her]". Even though he was born the same year as Elizabeth; when this film takes place, in 1585, he had already been dead for 8 years.
Continuity mistake: When Joan first meets with her captains in Orleans, they argue. She walks away and La Hire calls her "a helluva woman". As she walks away, you can see him looking at her. Immediately, she turns back, and he is now looking at the other captains as she walks up to him and belts him. He must have turned his head very quickly, too quickly to be caught on film.
Continuity mistake: Sacajawea (Donna Reed) dives into the water to retrieve some important maps, which have fallen in and been taken to the back of the boat. When she dives in, the maps are back to the original area they fell into, when they should have been quite a distance from where they landed in the water.
Factual error: There is a three prong electrical outlet visible in the Wershba's bathroom. These were not used at the time the film takes place, they were introduced decades later.
Continuity mistake: When the protagonists are trying to get to the French embassy they pass a VW beetle whose windshield is smashed by a Red Khmer. The camera angle is not very helpful but if you look closely you see that the window is gone already, and the pieces flying over the hood are from the bit of glass that sticks in the frame. (00:56:50)
Visible crew/equipment: When the slaves roll the flaming ball down the hill, we see it strike several Roman soldiers. Look closely, they are actually stuntmen dressed in asbestos suits.
Continuity mistake: Jesus is shown from behind on the cross with large gashes on the backs of his legs. He was flogged across the shoulders and back only at the pillar.
Continuity mistake: When Paul (the hotel manager) finds Timmons in the kitchen when Timmons had been shot and is bleeding, we see Timmons with his hands on his blood that is on his shirt. When Paul comforts him, he puts his bloody hands on Paul's white shirt, but when we see Paul outside the hotel, there is no stain from Timmon's blood.
Plot hole: When the Black & Tans are shown driving through the village, a blue house is visible behind them. The house has modern PVC windows.
Plot hole: The movie takes place before and around 1938 and, supposedly ends in that year, following the entrance in Shanghai of the Japanese, with the exodus by many Chinese and foreign residents. Ralph Fiennes' character, as an American ex-diplomat and businessman, would have resided, have bank accounts, his car, etcetera, in the foreign concessions. The Japanese did not occupy the concessions until after Pearl Harbor, so there was no need for him to flee the city, as a refugee without a passport and with little or no money, sailing towards Macao in a fragile Chinese junk. He could just have driven or walked a few blocks to any of the "Western" concessions, from where he could have married Natasha Richardson's character, obtained U.S. passports (White Russians had none, as the rest of her family in the movie until assisted by an official in the French Consulate) for her and her daughter, purchased a ticket in a safer vessel, sold his assets (regardless of the damage to his club, he still had a house, furniture, a car, presumably bank accounts, etc.).
Deliberate mistake: As the Soviet tank starts rolling, the tank commander obviously uses a hidden step to mount the tank. Soviet T-55/T-62 type tanks did not have steps for mounting by the wheels and axles; to mount a rolling tank using the moving wheels or spinning axles would result in the mounter being immediately crushed and killed.
Factual error: The movie depicts Col. Nelson Miles at the signing of the Fort Laramie Treaty which was signed April 29, 1868. Col. Miles is shown wearing a Civil War Medal and an Indian Wars Medal. The first Civil War Campaign Medal was issued in May 1909 and the blue and gray ribbon shown in the film was not in use until August 1913. The first Indian Wars Medal was issued July 1908. The ribbon shown in the film with two dark bands was not in use until 1917. Obviously, Col. Miles could not wear two metals that have not been created yet.
