Factual error: Not only Mulan's horse is able to outrun an avalanche (at the beginning even unseen by the large enemy army who does not even notice the event occurring), but it also gallops through it undisturbed while Honghui is being carried away depicted as being in serious danger. (01:09:30)
Suggested correction: This is consistent with what you see throughout the whole film: Mulan consistently breaks the laws of physics because her "Chi" is strong. (Translating it to the Star Wars lingo: Strong with her The Force is.) Five minutes before (video time, not in-film time) she reversed the flight direction of a spear. This is a fantasy film and is supposed to do all of this; we watch it knowing that magic, "Chi", and The Force are not real.
That's a composition fallacy.
Factual error: When John Thornton is in the bar, Hal comes up and punches him in the face. They fight and argue, and Thornton proceeds to say that Hal "sucker punched" him. However, the term sucker punch was first known to be used in 1926 while Call of the Wild was published in 1903. The story itself took place in the 1890s.
Factual error: There is no giant crater in the middle of Naperville, IL. Let alone at the end of a runway.
Factual error: Real-life Martina Franca is a town in Puglia, at the "heel of the Italian boot." The town shown in the film is the famous San Gimignano in Tuscany. And when Holly "defects" in order to go to the Hill of Tara, her departure point, as seen on Foaly's observation monitor, is the real-life location of San Gimignano. (00:35:50)
