Factual error: The weapon Palmer used to shoot down one of the enemy fighters was the M79 grenade launcher. This weapon's projectile speed is lower than the speed of the plane, so it would be impossible for Palmer to hit a target flying over 100mph side-by-side.
Continuity mistake: After Claire punches Peyton for the first time, there is blood on Peyton's face. When she gets up off the floor, the blood is completely gone.
Audio problem: In the scene where Malcolm is playing Russian Roulette, watch closely around the part when Malcolm begins to stand over the other guy with the gun pointed at his nose. You can hear Malcolm talking, but his lips aren't moving.
Continuity mistake: In the scene when Hando is reading from Mein Kampf he joins his girlfriend on the bed. In the next shot a half-smoked cigarette appears in his hand holding the book. This is not there before nor after.
Other mistake: When Tod is going outside to see a statue of himself, as he gets closer to the door he runs into it, but he actually jumps at the door.
Revealing mistake: When Nick returns to his apartment (after being made invisible) he immediately closes the curtains. Although he is invisible, we should see the curtains pulled closed at the point that he grabs them with his hands. Instead we see them close from the top, revealing they were closed either by a crewman or an automated process. Note: The curtains are NOT meant to be automatic in the film as we see and hear him physically close them.
Visible crew/equipment: A boom mike is briefly reflected in the office window when Lemmon and Spacey are arguing in the closed office. (00:25:45)
Factual error: When Chantel and Rhonda are discussing their high schools, Chantel says she is a doctor's daughter and grew up in the Pill Hill neighborhood but went to Du Sable. Du Sable isn't anywhere near the Pill Hill neighborhood, and even if it were, there's no way a doctor's daughter would have attended a high school that has for a long time been considered one of the poorest, most dangerous, and least academically well-performing in the city.
Continuity mistake: In the scene where the old lady comes out of the cafe and the children come out from behind with the remote control car, she shouts at them to get away. As she turns to cross the road the children turn to follow her. In the next shot when we see them out of the bingo hall they are walking ahead as if they had never turned to cross.
Continuity mistake: When Ray Liotta throws Madeline Stowe on the bed after she pulls the gun on him, he used his hands to pin her arms down. Then they cut to a different angle, her arm is pinned under Ray's leg and he's grabbing her hair.
Other mistake: When the girl throws a grenade at the closed window it rolls a bit and you see that the bottom has been drilled out.
Continuity mistake: When Bronx go to sleep intoxicated (the night the medicine man paints on her face) she is wearing a shirt and panties, but when she wakes up she is wearing a pair of jeans.
Continuity mistake: In the scene when Hasari comes back from work and he has got the school girl as a permanent customer, his friend goes to Kamla and tells her that Hasari has had a good day, and she closes the pot. Then a side shot of Kamla and Hasari is shown and you see her close the pot again..
Factual error: The old man is supposed to have accidentally ended up at Rita and Peter's wedding by just "getting on a train," and finding himself in Lake Forest (a far northern suburb of Chicago.) But he started out in Berwyn (a western suburb), and in order to get to Lake Forest from Berwyn, you have to get on one train, get off in downtown Chicago, walk several blocks, and then get on an entirely different line going to Lake Forest. In other words, not something you can "accidentally" find yourself doing, but something you have to know where you are going in order to do.
Continuity mistake: When Jacques attaches the bungee cord from the cocktail cart to Lazlo's pants, Lazlo takes a step forward and the cocktail cart snaps after him causing a terrible ruckus, however the bottles on the cart mysteriously empty before the collision, and none of them move. They are obviously glued to the cart.
Factual error: In the scene where Chaplin and his wife are traveling to Europe by ship (when they find out Hoover has expelled him from the U.S.), the film shows the French Liner "Normandie" as it is leaving New York. The date shown on the film says September 1952. The "Normandie" however, was destroyed by fire in New York Harbor on February 9, 1942 as it was being converted into a U.S. troop ship for World War II. Incidentally, they filmed the scene on the R.M.S. Queen Mary in Long Beach, California, which in reality is probably the ship that the Chaplins actually took to Europe.
Continuity mistake: When Chet and Stanley asks Irene some questions (in the café, about 15 minutes into the movie) about the murder, the cigarette Irene smokes changes a few times between the shots. Most obvious is the length of the ashes. (00:16:13)
Visible crew/equipment: After Jack jumps out of the plane he comes close to another Flying Elvis, who is being suspended from a visible cable.
Continuity mistake: There is a scene where dozens of police cars pull up the hospital's "driveway" to surround the building. In real life they could not be coming from that direction, the "driveway" is a park road that ends at a scenic overlook with no connecting streets.
Continuity mistake: Chapter 5 Abraham is shaving Director Po. It looks like he is just starting and Po is covered in shaving cream. They cut to Branick and when they go back to Director Po he has been completely shaved when it is clear Abraham has not done anything. (00:24:05)
