Character mistake: There was no chance of Will and Lori knowing what's happening with Mark in the house. Neither him nor anyone else called them. So what made them rush home with van, after they've been casually driving in their previous scene?
Character mistake: Alan Alda says that his personal security code is the street address that he lived on at Steinway Boulevard when he was a kid growing up in Astoria, NY. The name of the street in Astoria is Steinway Street. (00:19:50)
Character mistake: The protagonist says "You know, Croesus once said 'Count no man happy until the end is known'" but it's not Croesus uttering that line. According to Herodotus, Solon says it to King Croesus. (00:03:00)
Character mistake: The movie starts with shots of the moon Io and the company's operations, with typed descriptions at the bottom of the screen. Guess they couldn't afford a proofreader. They spell dependents as dependants, marshal as marshall, and principal as principle.
Character mistake: In the bathroom scene with the fat man tied up, Kevin answers his phone upside down.
Character mistake: Max back in London is referred to as Group Captain, but his RAF Rank shows him as a Squadron Leader.
Character mistake: During the game against the Cardinals in the playoffs, the announcer says that Averman passed to Guy who then scored. First, Guy does pass the puck back to Averman, but then he passes it to Banks who scores the second goal, propelling them to the playoffs.
Character mistake: When Rommel leaves his French headquarters for Germany on June 5th for his wife's birthday on the next day, he erroneously states that date as 6th of July (pronounced yoo-lee), not June (pronounced yoo-nee). (00:29:30)
Character mistake: After crashing their car into the bar the Tender Trio attempt to flee on foot but Clipper twists his ankle. Goose says "Goose f***ed up his ankle" accidentally referring to himself but obviously it's Clipper that twisted his ankle. (00:14:59)
Character mistake: When Murphy shoots down an F-16, the guy says "we just lost a M-16."
Character mistake: When Eric Roberts' character receives his letter at the start of the film it says "congradulations." instead of congratulations.
Character mistake: When Donnie (spotter) is giving Swagger ranges to fire, he doesn't tell Swagger what hold to use.
Character mistake: When Mary is in the execution chamber, about to be incinerated, there is a voice over of the countdown till her death. They count back from 9 seconds and say 8 seconds, 7 seconds, 6 seconds, etc. The count is too slow. Every time they say a second, it's actually two seconds having passed. (01:22:10)
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: The downed firetruck was referred to as engine 17, however it is actually engine 23.
Character mistake: When the police scan Leeloo the first time, the computer reads "Commencin" instead of "Commencing."
Character mistake: In the Air Force One scene, when lightning destroys one of the plane's engines, one of the pilots tells a co-pilot to inform Metropolis Airport that the president is on board the plane. The crew is unnecessarily repeating themselves: just a few moments before, they radioed in that "Air Force One" was on approach; the plane would only have that call sign if the president was on board.
Character mistake: Toward the end of the film, Detective Davis orders Captain McKenna to put his badge on the table. New York City police always refer to their "shields", not badges.
Character mistake: When Ripley asked the doctor how they "got" her, he replies from blood samples on Fury 16. This is in reference to the planet in Alien 3, but it was called Fury 161. (00:11:00)
Character mistake: When the American hands over the wills to Ian Fleming he calls him Lieutenant Commander, but when Fleming turns up at the camp he has gold braid on his cap - only commanders and above wear gold braid. Also they kept calling the RAF guy Flight Sargent but he didn't have a crown above his stripes.
