Factual error: The terrorist with the AK47 is unaware of the fact that a Harrier is hovering just outside the window until he slowly turns and see it there. He does a double take when he sees the Harrier just five metres away! A Harrier is an incredibly loud aircraft; you can hear them from three kilometers away. At that range the floor would shake with the noise and he would have been in no doubt whatever that he had been under attack for some time.
Factual error: During the 1972 New Year's Eve celebration, Forrest drinks a Dr. Pepper with a logo that wasn't devised until around the mid 80s.
Factual error: When Wyatt (Kevin Costner) becomes the sheriff/deputy/policeman of Wichita, Kansas, you can plainly see mountains in the background - there aren't any around there.
Factual error: When Mufasa is showing Simba the kingdom from Pride Rock they are facing the sun, yet Pride Rock's shadow is visible below them. Also in the same position, you see that they have shadows behind them. Then a few seconds later when Simba sees the shadow area the shadows are in front of them while you can see part of the sun to their left side. They would be facing south when the sun is east. How are their shadows in front of them?
Factual error: What on earth is the conductor at the premiere of the 9th doing with a baton? This was not used until around 1849, and the premiere of the 9th is in 1824.
Factual error: When Julia Roberts drives away from the building where she finds the dead body of the boy with "LD" written on his hand, it is raining heavily. Yet, as she accelerates, there is an extended sound of tyres screeching on a dry surface.
Factual error: When Pauline makes her first entry into her 1953 diary, the date at the top of the page is January 1, Thursday. Later in the film when she begins her diary for 1954, the date on the page is January 1, Thursday. The same date in two consecutive years cannot be the same day of the week, they are a day apart (2 in a leap year). In actual fact, 1 January 1954 was a Friday. (00:24:20 - 01:03:45)
Factual error: When Eric goes to help the guy who got hurt after bungee jumping at the dance, the guy's line is long enough to allow him to lay flat on the ground. If it was really that long he would have crashed into the floor and not gone back up.
Factual error: The comet is seen to move rapidly across the sky. This in actuality never happens as they are so far away. The speed shown in the film is more appropriate for a shooting star.
Factual error: During the battle scene the voiceover says that it is February 1915. The battle being portrayed is obviously the Second Battle of Ypres because it involves Canadian troops and it's the first time that gas was used in the war. The actual battle didn't take place until the end of April 1915.
Factual error: When the red BMW hits the curb just before joining the freeway he does so at 70. Hitting the curb at 70 would cause a blowout. (00:17:10)
Factual error: The entire court proceeding is inaccurate. Under New York state law, all property received during marriage is joint and several. Therefore Charlie has the right to give half (HIS half it turns out) to Yvonne. More strongly, the press is always called out for lottery winners to prevent these situations. The wife screwed herself when she agreed to have Yvonne at the check presentation which effectively shows her agreeing, albeit not happily, to the arrangement. Finally, to be even more picky, under New York state law, the person BUYING the ticket is the only owner and the other person must prove that the ticket was bought in trust for them (if it comes to litigation of-course). In most cases, people like the bowling team readily split the proceeds without a problem.
Factual error: Harry's tongue gets stuck to the chairlift, and stays stuck, even though it's not cold enough to see anyone's breath, or for everyone to need their jackets zipped-up. (01:11:30 - 01:13:35)
Factual error: Justine is accused of murdering Victor's young brother and is taken by police. A lynch mob takes her to the top of a fortress wall, drapes a noose around her neck and tosses her over the side. She falls for what looks like at least 8 metres. When the rope comes taut, she is killed but her head isn't ripped off by the force of the fall. Falling for that distance should have torn her head from her body.
Factual error: In the beginning of the movie, Dr. Bob Moore falls through the glass doors of his office and is impaled with the glass. This would never have happened. It is federal law that safety glass is used in all entry doors. The glass would have to have been made of tempered glass, which breaks into tiny pieces like a car window, or laminated glass which will crack and bend but stay intact like a car windshield, or of wire glass, which will act similar to laminated glass. None of these was used. A plain standard plate glass was used instead.
