Factual error: It is said in the film that Ice Cube's character works in an airport in Detroit. When the scene shows Ice Cube at work as a baggage handler, there are mountains in the background. There are no mountains in the Detroit area. (00:14:10)
Factual error: Just as Ralph Fiennes is getting out of a car to run across the road you can see, just as he steps out, road markings that were not around in the mid forties and that weren't on the road in a shot just previous when you could see the road behind Fiennes in the car window. (01:09:05)
Factual error: As Pellew and Hornblower return to the Indefatigable, they go aboard a ship's launch. In the Royal Navy, when boarding a small boat, the senior officer always boards last, so he can disembark first. Captain Pellew boards before Lieutenant Hornblower.
Factual error: In the very last scene the train is stopped by the Russian army and their tanks. The tanks are T-54's, which were not produced until 1955. (01:53:28)
Factual error: Early in the movie, the Dauphin receives another letter from Joan (or her writer). The only person who ever wrote to the Dauphin about Joan was Robert du Baudricourt, and he wrote one letter, and it was about Joan, not for her.
Factual error: Hornblower's plan is to sail Le Reve south from Gibraltar to give him ample sea room before he heads for England. Generally, the prevailing wind through the Straits is westerly, unless there is a Levanter, yet Le Reve is shown on a port tack when it should be on a broad reach. The fog that comes up would not exist in a gale-force Levanter.
Factual error: The British Major at the end has his rank crowns sewn to the collar of his shirt. The British Army didn't/doesn't do that. They should be on his shoulder epaulettes.
Factual error: Many of the French soldiers have American accents.
