Character mistake: In the opening scenes when Brian goes back to the shop, he demands that he needs some nitrous to boost his low top speed. Well I'm sure that most tuners will agree that more horsepower doesn't equal more top speed, it only contributes IF you have a transmission that can handle it and distribute it. (00:09:53)
Character mistake: When Wood is telling Harry the rules of Quidditch he says that if you catch the Snitch the game is over, which is true. But then he also says that which ever seeker catches the snitch, their team wins, but that isn't true. Granted that the 150 extra points probably would give you the winning lead, but as JKR pointed out in the 4th book at the Quidditch World Cup, you can catch the Snitch but lose the match. And you'd think explaining the rules to a first-timer you would want to get it right. (01:05:40)
Character mistake: When Col. Winter has Yates brought in to see him, Yates tells the colonel that his father won the "Congressional" Medal of Honor. This is a mistake, and one a lot of people make. The award is correctly and simply called the Medal of Honor, and one doesn't "win" the medal, it's awarded. (01:21:10)
Character mistake: When Jimmy explains to the kids of the town where the aliens took their parents, he mentions the origin of the aliens being somewhere in the Orion Star System, 3 million light years away. The Orion system is way closer than that. It is actually less than 1400 light years away from Earth. 3 million light years away would place them further than the Andromeda Galaxy.
Character mistake: According to Alan Turing, Enigma has "150 million million million" starting positions (1.5 x 10^20), while Shark has "4 thousand million billion", or 4 x 10^18). So Shark, the "ultimate refinement" of Enigma, has FEWER starting positions? (00:10:25)
Character mistake: When Ramathorn and Farva pullover the Plymouth Voyager, Ramathorn radios in and says they have a Plymouth Voyager, Vermont plates Alpha, God, Mustard, 1, niner, decade, china. When Farva gets out of the car to call the driver a chicken f**ker, you can see the licence plate, Vermont plate '1 9415'. Ramathorn radioed in the wrong licence plate number.
Character mistake: Cross knows (for some reason) by memory the last words of the Lindbergh kid kidnapper (and killer) and that Soneji/Mercusio referenced in a book he finds in amazingly oblique ways. He calls him "Richard Bruno Hauptmann", while his name was actually Bruno Richard Hauptmann. (00:42:30)
Character mistake: Near the end, Iris's doctor attempts to take John's pulse. He has his hand wrapped around John's hand, his fingers nowhere near the top of the wrist, where the artery is; and as he counts the "beats", against his wristwatch, John talks to him and he talks back - when you are counting something, you can not talk at the same time; you lose count every time.
Character mistake: When they find a Suicine, they ask Oak and he says it's a Swecon.
