Character mistake: When giving Eggsy a tour, Galahad tells him that Oxfords are any formal shoe with open lacing. This is incorrect as Oxfords have closed lacing.
Character mistake: Violet is in the Army, but does not have her hair up properly in uniform.
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: 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: 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: 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: 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 Bruno is picking up baby OJ, on the subtitles it says '13 pounds of black gold' whereas Bruno says 'vierzehn' which, in German means 14, not 13.
Character mistake: Gru doesn't recognize Nefario at the record shop, despite meeting him at Villain Con in the Minions movie. And given the fact that he can recognize all of his Minions without even asking them who they are, he should definitely remember seeing Dr. Nefario.
Character mistake: When playing Alex's game for the first time, the buttons Grandma presses are different to the buttons Alex describes. For instance, she presses the 'punch' button to use a spell, when she should use the left trigger.
Character mistake: During the Nativity play, Pastor Phil says, "Are we ready to see the result of the Immaculate Conception?" The term 'Immaculate Conception' refers to the conception of the Virgin Mary (conceived without Original Sin), not to the conception of Jesus. Furthermore, the Immaculate Conception is a dogma of the Catholic Church, and not something which a Protestant pastor like Phil would believe in.
Suggested correction: The immaculate conception refers to Mary conceiving Jesus. It was Immaculate because she was a virgin carrying God's child. The Virgin birth (Jesus birth) is in the New Testament and every Christian (Protestant and Catholic) believe the story of the Virgin Mary and birth of Jesus.
The Immaculate Conception is indeed the belief that Mary was born without Original Sin (and thus was immaculate, meaning spotless or clean), although some religions teach Mary was born in sin and made immaculate through the Holy Spirit. The birth of Jesus is known as the Virgin Birth (one could even use the phrase "virgin conception.") Immaculate Conception has nothing to do with being born of a virgin.
Character mistake: Griffin states about the New York Mets saying "They were in last place every single season until they won it all". That is not true. They came last ever since they started in 1962 to 1967. In 1968, the year earlier, The New York Mets came second to last where as The Houston Astros came last. (01:07:30)
Character mistake: Both in the movie (and stage) versions, Mushnik makes a verbal mistake. Seymour shows Mushnik his new plant (Audrey II) for the very first time, but seconds later when the plant suddenly droops, Mushnik asks Seymour, "Why is it always wilting like that?" Always? He's just seen the plant! The line should be, "Why is it wilting like that?" Some smart stage directors of the play version have wised up and changed the line.
Character mistake: In the beginning of the film, Doug Chesnick is on a plane returning to Washington. The flight attendant brings him a Bloody Mary with the Vodka in a bottle next to the drink on the tray. He drinks the drink without pouring in the Vodka.
Character mistake: The Finnish businessman says something along the line of "As Scandinavians - we like her". Scandinavia includes Norway, Sweden and Denmark, never Finland (or Iceland); a Finn would know that.
Character mistake: At the end of the movie, when Tony Curtis goes aboard Sea Tiger, the word is passed, "Attention on deck." Since he is the captain, the proper announcement would be, "Sea Tiger arriving."
Character mistake: In the end of the film during the protest, Ray Liotta is operating on a man. At the start of the operation Ray's surgical glove is torn, exposing the thumb on his right hand as he points into the opening on the patient's chest.
Character mistake: When Fish is offering Jack the contract to sell Henry to the Yankees, and later when Jack insults Henry's father, they both refer to Jack as Henry's manager. But Martinella is Henry's manager; Jack is Henry's agent. While the terms can be used interchangeably in other businesses, such as music, in baseball they are two separate titles with separate job descriptions.
Character mistake: After Ricky has just killed his girlfriend with the car antenna, he's challenged by a police officer. Officers would never walk right up to someone who have just committed a murder. Police would always order the suspect into a position that presents the least amount of threat and minimal chance of resistance. Grabbing the officer's gun would never had been an option.
