Factual error: When Bud-dha is meditating one morning, to his left is the way they came from, and to his right is the way they had been headed the day before (which they say is true north). But, He's facing the sunrise. The sun rises in the East, not the West, so the sunrise should be behind him. Then, after that, when the puppies set off again, they head towards the sunrise, though they're supposed to be headed "true north".
Factual error: Dante's last day seems to be in the fall season, judging by the amount of leaves on the road when he and Randal drive back from the Go-Karts. One of the last scenes is of all four of them outside the just re-opened Quick Stop and you can see that Becky is very much pregnant (at least 5 months) but the season is still the same (look at the trees). There should be snow on the ground in NJ at that time (Jan-Feb), or at least it would be cold enough to wear a coat and see your breath.
Factual error: When Scarlet decides to ram the other car, she asks 'Him' if there is a green Pontiac behind her. Him answers yes. In fact, the car is a Chevrolet Camaro, not a Pontiac. Him may be a detached actor that knows nothing about cars, but Scarlet knows the car and its owner well, and the owner's reaction proves the car hit was the intended target. (00:29:15)
Factual error: When Sherman creates the fake college website, he states that it ends in .edu, which can only be given out to an accredited university.
Factual error: When, on their second date, Jenny sucks in air and pulls a cab backwards, the driver spins the tires trying to go forward. The smoke rolling off the tires does not get drawn backwards towards the suction.
Factual error: Jenna calls her dad with the result of her sonogram, and reveals the sex of the fetus. But given the timing of the movie, we know that Jenna is between 10 and 12 weeks - gender can't be determined from a sonogram until at least 20 weeks.
Factual error: The 4th Infantry Division drives Bradley fighting vehicles, not LMTV's (trucks) as seen in the Iraq scene.
Factual error: While the film is supposedly set in the late 19th Century, the locomotive is oil-fired. The tender carries neither wood nor coal. There is no way the Mexican National Railroad would possess oil-burning locomotives in this time period.
Factual error: As Augusten Burroughs is taken to his mother's physician's home to stay, he notices Dr. Finch's wife, Agnes, intently watching the vampire soap opera "Dark Shadows." However, the year has been previously indicated as 1978 and Dark Shadows ran before that, from 1966 until 1971, so it couldn't have been on television.
Suggested correction: Dark Shadows would have been running in reruns at that time.
Factual error: To demonstrate his hatred of the England football team, Paul throws darts at a photograph of the players in their red shirts midway through the competition. However, the photo in question was taken after the final was played. Furthermore, in relation to the film's timescale, when the scene takes place neither the team or the choice of kit had been decided upon.
Factual error: In the beginning when the animals are waking up from hibernation, it shows Ozzie and Heather running out of the log, which shows they hibernated, but opossums don't hibernate.
Factual error: A soccer game does not end on a goal. The ball is always returned to the middle of the pitch for a kick-off, after which the game is ended by the referee. It is also highly unlikely no overtime is given in this game, seeing the number of interruptions.
Factual error: When Gray gives her dead boyfriend's friend her boyfriend's old high school T-shirt, he puts it on, you can see that it is a "tagless" T-shirt. You can see the imprint of the "tag" through the shirt. Those kinds of tags were not used when they were in high school that many years ago.
Factual error: When Julia gets on the motorcycle the engine starts with a turn of the key, and then turns off the kill switch. In real life the motorcycle starts after you turn the key, disengage the kill switch then push the electric start button.
Factual error: In the last part of the movie when the animals attack, one of the hunters call the warden. The hunter's phone is a SonyEricsson W710i. This phone does not support video calls and no camera on the LCD part of the phone where it fell forward and supposedly showed the videos to the sheriff.
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."
Factual error: Although "Myearth" is a fictional site for the movie, all satellite sites (such as Google earth, etc.) show images during daylight hours (though I've seen rare exceptions of images during twilight hours). How could Buddy expect to not see his house (with or without lights) when the images show during the day?
Factual error: You can tell that the "Brillo pad" Andrew eats is not real as Andrew would have been VERY ill due to the cleansing chemicals on the pad and the fact that the metal would have cut his mouth considerably. There was no blood, no foam coming out of his mouth (the box says Oxy action implying foam), and he keeps eating despite that the taste would have been horrible.
Factual error: In the scene where Alex is challenged by one of the testers to play Frog Bog, he shows it to Alex for the Xbox. Frog Bog was released for the Intellivision but wasn't available on the Xbox until 2010, after the release of this movie.
Factual error: Throughout the film, most Japanese words are spelled in Katakana. In real-life Japanese, however, Katakana is exclusively used for foreign words adopted into Japanese language, like 'table', 'television' (mostly it is abbreviated to 'telebi') and 'racing car'. But in the film, even indiginous Japanese words such as 'samurai' are spelled in Katakana, not - as they should be - in Hiragana (the syllable system used for native words).
