Character mistake: When Aubrey is telling the Bellas that they will practice two hours a day, seven days a week, the board behind her states that on Sundays they have the day off. (00:35:05)
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: During the opening space battle, Obi-Wan's ship falls under attack by buzz-droids, who proceed to cut into his fighter, disabling a number of systems and leading Anakin to try some decidedly dangerous moves to get rid of them. Both Anakin and Obi-Wan are acknowledged experts in the use of the Force and both have been shown to use the Force routinely, even for relatively mundane activities. It's also been firmly established that the Force works on droids and that the Force-user can still affect others through windows, viewscreens and so forth. Yet neither thinks to use the Force to deal with the buzz-droids. (00:05:10)
Suggested correction: There's no evidence this is a mistake. In fact, it's logically self-defeating. As you noted, both Anakin and Obi-Wan are trained Jedi Knights. If the option of knocking the droids off with the Force was indeed feasible, presumably they would have done it. There are any number of reasons why they didn't (they couldn't concentrate enough in the middle of a pitched naval battle to commit a Force attack, the droids could have been attached magnetically, etc.) but the bottom line is that if telekinesis was an option they would have done it.
Character mistake: As they take Han away, watch Lando. Just before he tilts his mask down so we can see who he is, he whacks his head on the doorway. (00:16:20)
Character mistake: The mother tells the daughter to keep warm and drink water. In fact that would lower the blood sugar faster. This method is used for high blood sugar to lower it back to normal.
Character mistake: When Picard is explaining the Enterprise to Lily he states that it has 24 decks. Yet earlier on, a crewman had reported to Worf that the Borg had taken over "decks 26 up to 11".
Character mistake: When Mike and the SAS team leader first meet, the team leader introduces himself as Will Davis, Captain. However at the near end when they say goodbye to each other, Mike addresses him as Lieutenant. (01:07:35 - 01:25:35)
Character mistake: Civil rights lawyer says bring up the 1983 case. Should have been 1893 or 1883.
Character mistake: When Angelo sets the Vulcan down in the sea, he blows the canopy and extends the landing gear. As the plane settles, he attempts to release his harness, then has his air line cut by Largo. He futilely beats on the harness release when all he had to do was pull the face curtain handles to trigger the ejection seat, which would not only blow him clear of the plane but would separate him from the seat itself. Having trained for two years for this specific mission, he would undoubtedly be familiar with ejection procedures.
Character mistake: When Jim gets home and finds the apple pie on the counter with a note from his mother, the note reads "you're favorite", rather than "your". (00:31:40)
Character mistake: While he may not have figured it out the moment he found the forest dying, certainly a botanist like Freeman Lowell would know plants need light to survive.
Character mistake: When Moss is arguing with the border guard at the Eagle Pass international bridge, he claims that he is a veteran of the "12th Infantry Battalion." There has never been such a thing as the 12th Infantry Battalion in either the Army or the Marines. Rather, they are based on a structure of 3-4 battalions per numbered regiment (i.e., 1st Battalion, 3rd Infantry Regiment/2nd Battalion, 5th Marine Regiment, etc). The film takes this seriously, as the guard, a veteran himself, buys Moss' story.
Suggested correction: He might have meant 12th Infantry Regiment. From Wikipedia: "Three 12th Infantry battalions deployed to South Vietnam with the 4th Division from August through October 1966."
If he said "battalion" but meant "regiment", then it's still a valid mistake for saying it wrong and being believed.
Regiments have not existed as functional units in the US Army since shortly after Korea; they are simply historic names associated with various battalions. Marine battalions are not numbered higher than 4 in any regiment, and in any case do not carry an explicit designation of "infantry."
Character mistake: The crew many times refers to the sub as a ship - subs are always called a boat.
Character mistake: When Richard Pryor is on the computer attempting to formulate Kryptonite to kill Superman, a screen shot of the computer shows the word "recieved." The I and E should be the other way around. (00:59:25)
Character mistake: When Ray and Winston are driving across the Brooklyn Bridge around midnight in the Ectomobile, Ray quotes a verse of scripture claiming to be "Revelation 7:12". What he quotes is actually Revelation 6:12. (01:03:38)
Character mistake: In the beginning of the movie, Chrissy goes swimming on the night of July 1. Her remains were found the next morning on July 2. The police report that Brody types up states that the incident happened at 11:50 p.m. On July 1 and that Chrissy's remains were found at 10:20 p.m. On July 2 and not in the a.m. As the movie shows. Also on the police report, it states that Chrissy was removed to the "CORNERS OFFICE" and not the coroner's office. (00:09:30)
Character mistake: In the scene at Roger Podacter's condo building, you hear the reporter mention that he allegedly leaped to his death from his own 20th story balcony. As the camera pans down, you can see the flashlights and people up on his balcony doing the investigation. This is the 2nd from the top floor. If you count the floors as the camera moves down, there are more than 20 floors to this building. The number is actually closer to 30. Even though it is difficult to get an exact count of the floors, it is still possible to tell with 100% certainty that his unit was on a floor higher than 20.
Character mistake: When they are having the going away party for Paul, "leisure" is spelled wrong on the cake.
Character mistake: When Edward leaves Forks, he does it because he believes that he will be protecting Bella. Except that he seemed to have forgotten that Victoria was still in Forks and was intent on killing Bella.
Character mistake: When Buquet hangs over the scene, you can see Meg screaming along with three other dancers. Four shots later, Meg is still screaming, but the two girls who were to her right (on the left of the screen) are still dancing, as if they haven't seen Buquet yet. (01:05:10)
