Factual error: When Rick is talking about the German guns shelling near Paris, he describes them as 77's (non-existent) - likely meant the famous 88's used as anti-aircraft and tanks as well as for wheeled guns. [The line was originally "88s" but was changed at the request of the War Dept. so as to not tip the German's hands that we knew about the 88s.] (00:44:25)
Factual error: After Pearl Harbor is attacked, all of the radios on the base are tuned in to Roosevelt's "day of infamy" speech. None of the radios were short-wave and FM wasn't widely available, so the likelihood of their hearing a live broadcast was slim to none.
Factual error: When the Yankees play Boston, a dirt path is visible going from home to the pitcher's mound. Fenway Park, where the Red Sox play, has never had such a thing.
Factual error: Orville says that he born on September 13, 1913, a Friday. That was actually a Saturday. (00:46:10)
Factual error: When we first see Bambi as an adult, it is meant to be the same year (no revolving of the seasons or such to denote time passing). Yet the adult Bambi seems to be three years old as his antlers have two 'tines' or forks on them. In a male deer's first winter he grows two straight horn-like antlers on his head, which is the first 'tine'. After this the number of tines on the deer's antlers increase one with each year. So, counting the year when Bambi was a fawn and had no antlers, he has the body of a 3-year-old deer. Yet judging by the story's progression and the relative ages of Thumper and Flower (remember, smaller animals mature faster) Bambi is only 2 years old.
Factual error: Although quite typical for biopics of this era, certain aspects of Cohan's life are glossed over. The movie shows him in a lifelong marriage to his first love. However, he was in fact married in 1899 to Ethel Levy, and after their divorce in 1907 he married Agnes Mary Nolan, who remained his wife until Cohan's death in 1942.
Factual error: Those in America, mainly in Massachusetts, weren't burned at the stake when accused of witchcraft. They were hanged. It was those in Europe who were burned at the stake.
