Factual error: Zippo lighters are sold dry, no fluid when new.
Factual error: In the scene where Clark is working on the lights the full moon is shown. This is December 14th according to the advent calendar. On December 24th when Santa's sleigh goes sailing over the moon, it is still full.
Factual error: If you take the train from Paris to Cannes you won't pass the Eiffel tower.
Factual error: Helicopter rotor blades do not unfold by themselves and there is no way to unfold them from inside the helicopter. A trained mechanic with the right tools and equipment (including the proper ladder for the job) will take a minimum of twenty minutes to rig a four bladed rotor, and that's if (s)he's in a hurry. An airborne (i.e. falling) helicopter? Forget it. (00:07:40)
Factual error: In the movie, when the baby is born and Big Momma delivers it, the baby comes out without any blood and there's no umbilical cord. (00:34:20)
Factual error: In the scene where Taylor is trying to prove to Gabriella that Troy is a dumb jock who doesn't care about her, Troy is in the locker room with his friends. Troy's friends are recording Troy on a camera attached to a PC, and the image is seen on Taylor's PC. The message on Taylor's PC says an incorrectly spelled 'Recieving WiFi Signal' instead of 'Receiving'. (01:00:55)
Factual error: In the scene where we first meet Rosie, it opens with a shot of the house and then goes inside, passing by some pictures of Rosie and her husband. One of them, a picture of their wedding, says "Frank and Rosie - Wedding 1948", but then when Rosie is talking about how her husband will know how much she still loves him after all those years, Robbie says that he hopes that he and Linda will be as happy as Rosie and her husband on their 50th anniversary. If they got married in 1948, they would be closer to their 40th wedding anniversary. Since the movie is supposed to take place in 1985, this would actually be their 37th wedding anniversary. (00:12:10)
Factual error: Shane is a lieutenant and the Principal is Petty Officer first class. Shane states the Principal is the senior officer. This is wrong as the Petty Officer is a Non Commissioned Officer, while Shane is a commissioned officer. Shane outranks the Principal.
Factual error: In the final standoff, Smith shoots Hertz by holding cartridges between his fingers in the fire. This is not remotely believable. The casings, weighing much less than the bullets, would have been blasted off while the bullets themselves would have gone nowhere. (01:15:15)
Factual error: During the drag racing part of the film, they show an orange Plymouth lining up to race a red 57 Chevy. When the back of the Plymouth comes into view you can see a Direct Connection license plate with a Mopar logo on it. Chrysler's Direct connection line didn't exist in 1964, and the red white and blue Mopar logo wasn't around until 1972.
Factual error: Opening the blank envelope, Marta finds the fragment of the toxicology report. It is signed "Office of the chief medical examiner, Norfolk County, Massachusetts." But then it writes also the address of said office, which is in Marlborough. Marlborough is also the city when Marta resides, and where the lawyers' letters we see come from. But Marlborough is also a city in the Middlesex county, not Norfolk. (01:28:25)
Factual error: The opening scene shows Donna graduating from New College in 1979. That is not possible, women were only first admitted in 1979.
Factual error: Finishing his rounds on the morning of Christmas Day, flying over downtown Chicago, the sun is over the horizon west of Chicago, Sunrises occur in the east, not the west. (00:26:10)
Factual error: When the shop vac shoots the golf ball at Mr. Wilson's gonads, it only affects him for around ten minutes. The shop vac was able to shoot a glob of paint over 50 feet in the air so the speed and impact of the golf ball would have done much more than put Mr. Wilson in extreme pain for a short while. The impact would have likely caused internal bleeding, swelling, causing him to vomit, probably a rupture, requiring him to be hospitalized. There is no way he is walking away from that, he wouldn't even be walking at all.
Factual error: In the beginning of the movie when the main character is watching ESPN. The footage of the Dallas game, where the referee (Cuba Gooding) messes up the coin toss, you clearly see the sky right over the crowd in the stadium. The ESPN people say it was in Dallas. In Dallas, the Cowboys play in a dome. The hole of the dome is in the center of the roof and the sky would not have been shot so easily. Also the dome has artificial grass. The footage showed natural grass. (00:05:35)
Factual error: The electric guitar Marty plays at the "Enchantment Under the Sea Dance" is a Gibson ES345. This guitar model debuted between 1957 and 1958 yet he's supposedly playing it in 1955. It would have been more accurate to have him using a Fender Telecaster (1950) or Stratocaster (1954) or a Gibson Les Paul (1952). (01:23:50)
Factual error: In the scene where the camera shows Times Square, visible on the right of the screen in the front of the shot is a poster for the Broadway show "The Lion King". The Lion King just celebrated 10 years on Broadway and was not playing in 1994.
Factual error: In the title sequence, Poppy rides her bike down Kingsway, along the Strand, and south over Blackfriars Bridge. The next shot of her shows a street with an EC1 postcode (north of the river) and the following shot an SE1 postcode (south of the river again).
Factual error: Laredo drives the ship out of the starship docking station and scrapes the main hull on the walls. This would not be possible without either scraping the wings first, as they are much wider than the main ship, or turning nearly sideways, which they clearly don't.
Factual error: There is no way Josie could have heard Alan M at the concert. First of all, she has a headphone in her ear, so she can hear herself sing, and second, the crowd is so loud, it's hard to hear people in the front row, never mind several rows back where Alan M was bodysurfing.
