Character mistake: Dumplin' is looking through her aunt's belongings, and finds an old application form for the Miss Teen Bluebonnet pageant. The application has an August 1993 signature but marks Lucy's DOB as 5/5/79 with a stated age of 16: it does not add up, as she'd have been 14 instead. Granted, it's an application she never actually turned in and not an official document, but this does not justify the mistake in the context of the movie (not to mention that had she just been too young to participate, the point of the movie would be moot).

Character mistake: It's merely training, but her opponents are hostile and want to exclude her from playing, so it's funny then that they don't call Kim out for her actions being egregious fouls; she brings the ball trapping it between her feet in multiple cartwheels (you can't just hold the ball between your feet for prolonged amount of times and 'carry' it). You could also say she kicks the ball at an opponent's face on purpose, which is equally unsporting. (00:24:00)

Character mistake: Pete says that Terry Bradshaw's corvette is a '75 stingray. It is actually a 1981 or 1982. 1975 corvettes had a rear window that was perpendicular to the ground. 1978 and newer had a sloping rear window.

Character mistake: The 911 operator told Margot, "He [intruder Griffin] sounds harmless to me" and Margot said, "Fine", ending the 911 call. The 911 operator should follow protocol for an intruder (especially since there was the possibility of a another intruder in the house), not make a subjective assessment of the situation based on the conversation between the resident and the intruder. (00:30:15)

Character mistake: Right after the firefighters have removed Flick's tongue from the flagpole, notice the police officer on the left (Flick's right). He is wearing his sidearm on his right but his Sam Browne cross strap is attached to his belt on his left. The whole point of the cross strap is to support the weight of the sidearm, so the officer is wearing it backwards.

Character mistake: The name on the sign of the pub/private members club of the Manchester United fans is spelt incorrectly: It should read "The Feisty Goat" but Feisty is misspelled on the sign as "Fiesty" instead.

Character mistake: The movie opens with the infant Molly Brown in a basket being swept down a raging river. She crashes and crawls up on the bank. No one else is around. But when the grown-up Molly tells her "pa" that she's going to Denver, she says, "Thank you for pulling me out of the flood."

Character mistake: After the math club students, in unison, cited pi to 3.141592, Percy continued with "65839" - but only the "65" are correct. He should have said "65358..." before being cut off (or "65359" if he was rounding up the last "89793238"). Even though the movie is classified as a comedy, Percy was showing off, but he was wrong. Charlie, Math Club Advisor, also committed a mistake because he stopped Percy by saying "Percy, we got it. Good" (as though Percy was correct). (00:04:29)

Character mistake: When Will finds April's lost copy of Jane Eyre, the book shop clerk reads the inscription written by April's dad and says it's a quote from the book. It's actually a quote from Bronte's poem Evening Solace.

Character mistake: The most Michelin stars a restaurant can get is 3, not the 4 Adam Sandler is talking about.

Character mistake: In the movie they grab Genghis Khan in 1209 which would have been correct, he ruled Mongolia from 1206 to 1227. In the presentation at the end they say in 1269 he did this and that, that would have been Kublai Khan's reighn of terror in Mongolia.
Suggested correction: Bill and Ted have proven not to be that smart. Easy for them to get those things confused.

Character mistake: In the final sermon, Henry says "Uncle Henry" instead of Uncle Harry - as shown in the earlier typed sermon.

Character mistake: When Mick arrives at walkabout hotel, Nugget introduces himself to Mick as if they have never met before. Yet in the first movie, Nugget is asking how Mick is getting on in New York. It may be just a case of over familiarity by Nugget but it doesn't make a lot of sense.
Suggested correction: It's quite possible that they haven't met, but Nugget's heard about Mick, e.g. from the people in the bar, stories, etc. Having no doubt heard so much about Mick, Nugget probably feels like he knows him, at least enough to ask how he's getting on.
I think it was just a scene to introduce the audience to Nugget. I'm pretty sure that if Nugget was a regular in that bar, then he must have known Mick.

Character mistake: When Carrie says to Bandit "are we doing 110? We're doing 110!" there is a shot of the Trans Am's speedometer. The needle is pointing to 110 on the kilometers per hour dial. On the miles per hour dial, the needle is pointing to a number between 65 and 70.

Character mistake: When the minion tries to get out on the top of the small car, it faces forward, but two shots later, it is now facing the back.

Character mistake: When the alarms go off in the police station indicating the code 187 all the police officers are confused as to what is going on since they know nothing of MDKs. Zack Lamb should have already known what the code meant, yet he never says anything and just waits for everyone to figure it out.
Suggested correction: I took it as he went into almost shock that after so many years a murder had actually taken place. He says, "I don't believe it," indicating he knew what the code meant but then he kind of froze until Phoenix's name was mentioned.
Suggested correction: Zack Lamb is quite old and it's possible he simply forgot what the code meant. He was a pilot too, not a street cop.
When Stallone first meets Lamb after being thawed in the future, he tells Spartan he was "grounded" after the events in the opening scene so had not been a pilot for 36 years.

Character mistake: When the Smiths first enter the store Home Made, the camera pans around and faces the store's large display picture which reads, "The true measure of a home lies in it's kitchen," but the word "it's" should be "its."

Character mistake: When Mr. Rogue is spinning the globe to assign countries to the students he spins for Albert Morio, and he puts his finger just west of North America and says "Lebanon." Lebanon is in Asia, slightly northeast of Egypt and we can see Egypt on the globe on the other side of where his finger is at. He's nowhere near Lebanon.

Character mistake: After George reads his speech to Lucy, she says it was fine except for "the split infinitive near the end." There was no split infinitive. (For example, "to boldly go" is a split infinitive; "to go boldly" is not.) (01:29:00)
Suggested correction: She was joking. She was trying to find something to criticise in his speech because she was still angry so she made something up.

Character mistake: After the things let the dog out, Larry calls Joan and tells her that the kids let him out, and he will get him (the dog). Later, when he's downtown with the dog, he has the line about "when Joan finds out you've escaped, Conrad's out and I'm in". Where is the surprise? He already called her, so she knows!
Suggested correction: With exception of the Royal Canadian Mounted Police, the Sam Browne belt shoulder strap is typically worn over the right shoulder and attached to the belt on the left side.
This is correct for military uniforms - once again, the Sam Browne is used to support the weight of a weapon (in the military, this would be an officer's sword, always worn on the left side). However, for police uniforms, the shoulder strap is worn over whichever is the non-dominant shoulder (usually the left). Once again, this is to support the weight of the duty weapon. If you look at agencies such as the Kansas Highway Patrol, New Mexico State Police, and various police honor guards throughout the U.S., you will see that the strap is worn primarily over the left shoulder, since most people are right-handed and therefore would wear a duty weapon on their right side.
