Factual error: The scene where Nightfox steals the Faberge Egg is all wrong. A laser security system must have a photoelectric receptor at the other side to detect if somebody pass between the two devices. As shown in the film, the laser beams points everywhere, so the system can't work and somebody could cross a beam without starting the alarm. Even if it was some weird system based on measuring distance it wouldn't work - if the laser hits the floor at an angle it won't bounce back to the source, it will reflect towards the ceiling.
Factual error: Near the beginning of the film there is a map of Europe with the countries coloured in using their respective flags. Great Britain is coloured with the Union Jack (Union Flag) pattern but so is the Republic of Ireland (Eire). The Republic of Ireland is not part of the United Kingdom (the political state) or Great Britain (the geographical term for the island), only the British Isles - they are a separate country and the Union jack is not their country's flag. Only the north or the Irish landmass (Northern Ireland) and Britain should show the Union Jack. If they are using an "old map" it would have to be very old, before the 1920's.
Factual error: Novorski buys a small hamburger at Burger King for 74 cents. Airport fast food restaurant menus are priced higher than restaurants in the city. Even if a dollar menu was available (usually not at airport locations), you can't get a burger at an airport for 74 cents.
Factual error: Flynn says that the chamber in the Mayan temple is "an exact replica of their great temple of Teotihuacan." But Teotihuacan was not a Mayan city, but rather the hub of a separate civilization (themselves called the Teotihuacan). It was in central Mexico, hundreds of miles from the Mayan area in the Yucatan Peninsula.
Factual error: Peter and Lizzie play their semi-finals on the same day, but the men's semis are the day after the women's at Wimbledon (unless there has been significant rain, which there wasn't).
Factual error: During the Thanksgiving sequence, all of the characters are outside in shirtsleeves. This is odd as by November, it is cold in Wisconsin.
Factual error: After putting Jenna in the closet, everyone crowds together and plan to leave. One girl holds a diet coke can, which is obviously a more modern design, and not from 1980's. (00:10:30)
Factual error: In the scene where the fireflies light the fireworks there is one problem: The chemical that creates light wouldn't ignite the wick on a firework.
Factual error: In the scene that takes place in Ollie's office after the death of his wife, he is talking to Arthur Brickman who is sitting in front of a plaque for the band Songs:Ohia's album, "Ghost Tropic." We know that the scene is happening 7 years in the past, because Gertie is a baby. "Ghost Tropic" wasn't released until November of 2000.
Factual error: As the Hood approaches central London in Thunderbird 2, they fly through Tower Bridge and over HMS Belfast, approaching from the East. However the onboard display in Thunderbird 1 shows TB2 approaching from the West, somewhere over Hammersmith.
Factual error: Right after the movie title is shown, you can see in the background a UPS truck. The only problem is that it has the new logo on the side of it. (00:02:00 - 00:06:00)
Factual error: When the babies are born, there are no umbilical cords.
Factual error: When Derek is calculating how much explosive Mentos to put in Cody's mouth to get the microchip out, he says to himself, "a thousand nanograms equals 1 microgram". While this measurement is correct, it is highly unlikely that any explosive would be of use in even milligram quantities. So 1/1000 of a milligram (a microgram) would be virtually useless, and measurements of 1/1,000,000 of a milligram (a nanogram) would be even less than useless. He couldn't have been calculating explosives in such small quantities. As well, Mentos mints are about 37.5 g (http://home.socal.rr.com/mentosfaq/candies.html), and he then cuts it into approximately 1/8 - micrograms would measure 1/250 of a mint, and nanograms would be 1/2500 of a mint. (01:12:30)
Factual error: This may have been considered before drawing it this way, but it's a mistake nonetheless: When Tinkerbell shows up at the end with all the other Disney characters to watch the movie, she is back lit and silhouetted just like everyone else, and so is the pixie dust she is trailing. This is done simply to resemble a dark theater full of patrons, not to play some sort of impromptu guessing game. Her pixie dust has always been luminescent so it should not appear as a shadow against the theater screen. It'd be impossible to be silhouetted to that degree if it gives off its own light.
Factual error: Near the end of the movie where H&K are stealing the skateboarder's truck, there is a Shoppers Drug Mart in the background. Shoppers Drug Mart stores are only located in Canada, not New Jersey.
Factual error: When the children jump off the remains of Aunt Josephine's house, they jump further than they'd be able to. The slanting floor, at least, would reduce the distance, plus they didn't take enough of a run up to jump the gap.
Factual error: The hairy girls claim they are in a giant Redwood named Earthchild. The only Redwood trees in Oregon are in the far South West corner very near the coast and mostly over the border of California. D. B. Cooper was supposed to have landed North of Portland. (00:57:40)
Factual error: When they are reminiscing about the riots of 1968, when Dr. Martin Luther King Jr. was killed, they show people looting in front of the barber shop. However, in 1968 Calvin's dad would never have owned a barber shop on Chicago's Southeast side where the movie was filmed, because black people were not allowed in that area near the beach.
Factual error: Toward the end of the movie just as Austin and his team start the football game, the camera shows the scoreboard counting down from 15:00 minutes, the problem with this is high school football games are played in 12:00 minute quarters not 15:00.
Factual error: The mall that the plastics state they are going to, Old Orchard as stated by Cady, is an outside mall. However, the mall they go to is an indoor mall.
