Character mistake: On the way approaching town the camera pans to a woman's hanged body with a sign written in German around her neck. One of the crew asked Wardaddy what it said, to which he answered something like "It reads 'I am a coward who refused to fight for the German people'." That sign actually translates to "I wanted my children not to go fight" or Anglicized for better effect, "I refused to let my children to go to war." Interestingly, once into town, there appears the corpse of a hanged man with a sign written in German that does translate to what Wardaddy said of the first sign.
Character mistake: The doctor diagnosing Will's illness tells Evelyn and Max that it's caused by "an isotope called polonium." Polonium is a chemical element, not an isotope. The word "isotope" refers to a form of an element (such as carbon-12 or carbon-14) not the element itself. It does not mean "radioactive substance", because many isotopes are stable. A doctor would know this. (00:17:00)paolog
Character mistake: Baymax, a healthcare robot, says that his programming includes a database of 10,000 symptoms of disease. Yet, he issues the warning, "After eating, wait one hour before swimming." That warning, often given by parents to their children, has no basis in medical fact. People who do not get cramps after eating will not develop cramps by going swimming after eating: http://www.snopes.com/oldwives/hourwait.asp.
Character mistake: When he called for a dinner reservation for 12 at his home it should have been 13, as he put 13 men down. (00:32:05)
Character mistake: In the bathroom scene with the fat man tied up, Kevin answers his phone upside down.
Character mistake: When Jesperson imagines himself as a Mountie his uniform is completely wrong and is not even the right colour. As it was his ambition to join the force and he has photos of RCMP officers in his cab, it seems unlikely that he would imagine himself in a completely incorrect uniform.Necrothesp
Character mistake: All the characters wearing gas masks are wearing them with the straps over the hoods. I was army trained, and you always wear the mask next to the skin for best seal, with the hood over the top.
Character mistake: When Mr. Rogue is spinning the globe to assign countries to the students, he puts his hand on North America, or just west of it and says "Lebanon." Lebanon is in Asia, slightly northeast of Egypt and we can see Egypt on the globe on the other side of where his finger is at. He's nowhere near Lebanon.Bishop73
Character mistake: At the end of the movie, when Jaggu is listening to the sounds recorded by PK, the audio contains the question which she asked, "Tumhare planet pe sab aise hi hote, bade kan wale?" but does not contain the answer which PK gave, even though he was sitting right there. This seems to suggest that PK did not exist in the real world.Yashbhatt
