Factual error: When the fish tank has been cleaned by the newly installed laser fish cleaner, the machine states that the water temperature is '82°.' In Australia the Celsius scale is used; therefore, it should be about '28°.' Australia is 100% metric and has been since 1974! Nobody in Australia - nobody, anywhere, any time since 1974, uses imperial measures. There is absolutely no question of the dentist having an imperial thermometer or expressing himself in° Fahrenheit. It is actually illegal to import or sell any instrument using 'Imperial' scales. You couldn't buy a Fahrenheit thermometer if you tried. (01:14:30)
Factual error: When Woody is looking at Andy's high school graduation picture in his room, there is a concert ticket in the upper left corner of the screen and another one just below it for a band called "Humble Beginnings" both with a date of Saturday, November 17, 2009. This date fell on a Tuesday. (00:11:15)
Factual error: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in, despite that trash having been compacted. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a densely compacted cube. (00:02:30)
Suggested correction: You haven't noticed the exact shape of his body. The back sticks out a tad. Garbage fills the space and the back pushes in to compress it.
Factual error: The size of the shadow of an object depends upon its distance from the light source, not the surface it falls upon. Lifting the cutout of the bird a few inches closer to the sun as they do would make absolutely no difference to the size of its shadow, yet it quadruples in size.
Factual error: If the access hatch to the nose wheel well on an airliner was opened at any time during the take off run every alarm panel in the cockpit would light up like a Christmas tree. The pilot would immediately abort take off.
Factual error: When the plane is attacked by missiles, Helen punches a button on the cockpit console and a screen lights up that says "chaff". The next shot shows the rear of the plane with several burning items coming from it that are supposed to be chaff. However, chaff containers burst open into thousands of radar-reflective strips that are meant to confuse radar-guided missiles (see real chaff in the movie Air Force One). What actually comes out are flares that burn extremely hot to confuse heat-seeking missiles. While it might be suggested that we just never see the containers burst open, later in the missile chase we see the exact same items in view for a much longer time and they never burst open.
Factual error: When the soldiers are asked to find out what gifts Andy is getting at his birthday party, the set out down stairs with half of a baby monitor. Well, any parent who owns one knows that there are 2 pieces to a baby monitor. One half (the larger half) is the receiving end (that takes in the noises) and a smaller half which is the transmitting part (the half that sends out the noises). The half that the soldiers take downstairs to talk through is the wrong half. They take the half that the noise comes OUT of. So, really, they should NOT be able to speak into this part - in real life, they'd hear what was happening up in Andy's room. (00:09:18)
Factual error: In the scene where Waternoose and Sully are talking, Waternoose gets himself some "coffee", which is sludgy and thick and takes quite a while to pour from the machine. Seconds later, he takes a very quick sip. Since the liquid was so thick and there was little in the cup, it would be impossible for it to pour that fast.
Factual error: At the start we see some neon tetra in the background. Tetra are fresh water fish. Not saltwater. (00:05:00)
Factual error: After trying to get his balloon back, Carl Jr. falls and breaks his arm. The ambulance that picks him up has a modern-day electronic siren, when in the 30's it would be a mechanical siren and would be much smaller.
Factual error: In the credits, there is a paper revealing that Mater was knighted on Tuesday, July 15th, 2011. However, July 15th, 2011 was on a Friday, not a Tuesday.
Factual error: When Elastigirl receives her new bike she discovers it's electric. Later, when she is rescuing the train, the bike hits a mountain and is destroyed in a fireball. What is making the fireball? It's electric so there is no gasoline/diesel to make a fireball, and a lithium explosion doesn't look like that. (00:33:30)
Factual error: In the end credits, some of the vintage advertisements have 770 area code phone numbers, which while valid for Atlanta, Georgia and surrounding areas now, it didn't exist until 1995 when it was assigned. The numbers should have had either a 404 or 912 area code since those 2 area codes covered all of Georgia until 1992 when area code 706 was implemented.
Factual error: In the Radiator Springs courtroom there is a Latin motto over the doorway, that should read "Justitiae via strata veritate" Which means: "The path of justice is paved with truth." But the first word is spelled wrong as "Justitae."
