Factual error: Ana's mother, "a French divorcée," according to the movie, teaches at cepe, which is a college within the National Autonomous University of Mexico specifically for foreign students. However, I attended cepe, and non-native Spanish speaking teachers would not have been allowed to teach there, as the entire point of cepe was to introduce the Spanish language and Mexican history/culture to foreign students.
Factual error: During the baby shower scene (which is on a Sunday) a U.S. Postal Service truck is seen putting mail in mailboxes.
Factual error: The Kiss of the Dragon acupuncture point, known as "Point 15," is in a delicate area of the spinal column, a little below the second cervical vertebra. It's a definite knock-out target in fighting, and it can even be a lethal target. But Jet Li's explanation that it somehow prevents blood from flowing away from the brain is pure nonsense.
Factual error: All SS members have right collar tabs, except Heinrich Müller. His rank at that time was SS-Gruppenführer, same as Otto Hofmann, but his collar tab corresponds to SS-Brigadeführer (one step lower). For addition, the collar tabs of some general ranks changed after April 1942. The conference took place in January 1942, so they have older versions. But as I wrote, Müller and Hofmann were at the same rank, so the tabs should look the same.
Factual error: Just before the cross scene a guard is holding an AK47 which was not invented until 1947.
Factual error: The canteens used by US troops in a couple of the scenes are the wrong type. The twin handle design M1956 came out in the mid 1950s.
Factual error: At the beginning of the movie there is information, that "Poland surrenders to the Germans after less than a month of fighting." In fact, the last big battle during Invasion of Poland (Battle of Kock) took place between 02-05 October, more than a month after first shots were fired. And Poland also never officially surrendered to the Germans. (00:03:30)
Factual error: Just before the band records their first EP Ride Into The Sun, the drummer quits. Rick Allen is shown to audition, is hired, then plays on the recording. In reality, Rick was hired after the recording of the EP. For the recording of the EP, Def Leppard recruited Frank Noon of The Next Band to play the drums.
