Other mistake: In the beginning of the film above the box office the date says April 12. When Sidney looks at her watch the next morning it's not even close to that date. (00:00:35 - 00:12:55)
Suggested correction: The mistake is correct, but the watch part has nothing to do with the incorrect date. It is the next day.
Other mistake: In the scene where Ripley throws the basketball at Johner, Christie says to Ripley, "Ok, I've got a new game, tag .." He hits her with the handles straight in the face once, he misses the next shot, misses again, and Ripley hits him to the ground, but you neither see or hear the handles fall. (00:23:15)
Other mistake: When De Niro and Bridget Fonda are talking and trading hits off of bong, alone in the apartment, while they're talking there comes a pause where they both look at each other with their mouths closed, and you can here someone coughing in the background.
Other mistake: While fighting Mr. Freeze (and Bane) at the Gotham Observatory, Batman, Robin & Batgirl all have batsuits on, with silver bat (or robin) symbols on their chest. But while they are giving Alfred the cure to Stage 1 of McGregor's Syndrome, for some reason they have changed clothes before giving him the cure. Because now (other than the fact that they have all taken off their masks) Robin has on his original robin suit (with the red robin symbol across his chest) and Batgirl has on a gray t-shirt. (01:55:25 - 01:56:15)
Other mistake: On his own computer, Sean looks up his son's file, which states the boy died immediately and his date of death was September 9th, 1991. When Eve and Castor (as Sean Archer) are at the cemetery, the date of death on the headstone is September 24th, 1991. (00:21:15 - 01:14:50)
Other mistake: When they look at the negatives on the boat there is the typical holes at the top and bottom of the negative. Then they magnify a part within the picture. After they look at the magnified part, but the holes are still there.
Other mistake: In the subtitles, when the Russians are locking onto the US Army helicopters, "Attack" is incorrectly spelt "Atack".
Other mistake: In the scene in the beginning when you first see the fifth element, and the camera moves up so you see the wide open mouth, look to the shoulder on the left. In the years of undisturbed dust, there are a few finger prints. (00:09:35)
Other mistake: General Ivan Radek (played by Jürgen Prochnow) is listed as General Alexander Radek in the closing credits.
Other mistake: When Exley talks to Vincennes about Rolo Tomassi, Guy Pearce's Australian accent accidentally slips when he says, "I just wanna solve this thing." (01:26:20)
Other mistake: Toward the beginning, when the characters wonder aloud what the rumbling noise is, someone suggests that it's the ventilation system, to which Rennes responds "No vents." However, in the passages between rooms there are panels with ventilation slits in them (which you can plainly see even as Rennes says the line), and it's pretty impossible that the characteristically level-headed and observant Rennes wouldn't have noticed that.
Other mistake: In the scene where Taggart is giving the lady a ride to her home, they're driving down a curvy road, sunlight coming through the trees, etc. This same footage is used later when Taggart is being pursued and battered by the semi.
Other mistake: Just after Rico and Ace rescue Carmen, the other guy has hold of the nuke, which explodes. Watch when the rocks collapse behind the three characters, you can see a nice square block lower from the ceiling, almost like a door being lowered. The crew could perhaps have made it look a little more realistic. (01:55:00)
Other mistake: Roark burns his hand on a hot frying pan and drops it to the floor. The dog then immediately wanders in to eat the spilled food. The pan should still be scorching hot after a short time, and yet the dog licks it without burning its tongue. (00:03:30)
Other mistake: When Cesar asks Trevor if he ever seen deer hunter; when the camera goes on Trevor, if you look closely you can see Stevie kinda smiling.
Other mistake: Alex jumps from the deck to the stern and falls into the sea. The ship moves at a speed of about 15 knots, and there is no chance that in a few seconds Alex could climb back to the ship, because he would be at least 50 feet away. (01:26:55)
Other mistake: When Andy places the wedding ring on Serafine's finger after jumping off the Statue of Liberty, he places it on the index finger. Don't people usually put a wedding ring on the ring finger?
Other mistake: When the plane is at Carson City for exchange of prisoners, the guards have jackets with 'Dept of Prisons' printed on the back, but there is a bus with 'Bureau of Prisons' written on the side. (00:35:50)
Other mistake: When Jerry buys "The Catcher in the Rye," the cover is upside down. When facing the front cover, the spine of the book is on the right side, instead of the left.
Other mistake: I've always wondered where they got the wood to make the enormous fire on the top of the mountain. You can clearly see that there are no trees anyway nearby, (except for several hundred meters further down) and they are not carrying wood with them either.
