The ketchup bottle sitting on the grill (at the kid's birthday pool party) is a squeezable plastic 'flip-top' ketchup dispenser with a distinctly modern label. This particular ketchup bottle did not exist in the mid-1980s.
A scene showing Charlie return home to his teen aged boys attempting to build a small airplane, shows, in the background, a mid 1990s Oldsmobile Achieva driving by but the scene takes place in the late '80s.
Shonte Jr. complains about Pluto being a planet, saying that no planet has an elliptical orbit. All of the planets have elliptical orbits; Pluto's orbit is only more eccentric, and isn't in the same plane as the rest of the Solar System.
When Charlie and Irene leave for New York, the Colonel and his assistant are talking about him being a liability. The assistant says "But Captain, Police Work is Charlie's life...", incorrectly addressing the Colonel as a Captain.
The Ford LTD 2-door belonging to the "Barber Shop Car Owner" is a 1979 to 1982 model when it's parked out on the street. However, it changes to a 1983-1987 model when Hank crashes it through the window; the grille changes completely.
The scene at 49 mins where the three sons are talking to the police near the tents, the muscular son is seen to wear a grey, tight fitting vest with black trim. It cuts to a two shot and he is wearing a grey loose fitting vest with no trim. Then back to the wide shot and is wearing the tight grey vest with black trim again.
Right after Charlie and Irene push the car over the cliff, Charlie asks Irene if she grabbed the wallet off the dash and she says no. Later in the motel, when they are lying in bed, Charlie is sharing family pictures with Irene and they talk about carrying pictures in their wallets. Charlie's was at the bottom of the lake with the car. [The deleted scene on the DVD doesn't really help - in it Hank jumps off the cliff to get his wallet, and then Irene follows. However the movie shows Charlie and Irene looking down the 30 meter high cliff and walking away with dry clothes. Deleted scenes can "disallow" a mistake only if they fill in plausible back story, rather than contradicting the "proper" movie directly.].
At the restaurant when Charlie yells to the kid with the milkshake, the child drops it and makes a puddle besides their table. In a few shots later the amount of milk increases and moves away from the table.
Right near the end of the movie when Irene is saying goodbye to Charlie, her makeup is a lot darker to when she is driving away in the car, it looks a lot lighter and rubbed off. When she is pulled over again by the police and gets out of the car her makeup is once again a lot darker.
In the scene where Irene and Hank are driving along in Gerke's car and Irene is holding the dart in her hand there are some inconsistencies: 1) The right window is sometimes open, sometimes closed. 2) When she is threatening Hank with the dart her hair is sometimes hanging over the dart, sometimes not. 3) Her seatbelt is sometimes on top of her collar, sometimes under it.
When Hank goes after the four baseball players the one whom he gets involved with is grabs a beer bottle. The camera cuts to Hank, then back to the four guys, and the beer bottle is gone although the man is leaning against the truck in exactly the same way as before. This happens before he may want to get his hands free to attack Hank.
After Charlie tells Irene that he is schizophrenic they hold each other by the hands. When the camera is on him her arms are bent at the elbow, and when the camera is on her her arms are stretched out.
The movie starts out in the present and then flashes back. The skinny trees in front of the house are tall in the beginning and in the flashback they are small. They grow a little more every time it's been a few years, but when they come back to the present, the trees are still only half grown in one shot. In the next, they are fully grown.
At the beginning of the movie Charlie and Layla are sitting on the sea side. After he asks her about her readiness to live on whale blubber in case he gets assigned to the arctic their position changes from resting on their hands to resting on their elbows.
In the scene where the three Baileygates brother's are in a field with tents etc, helping the police to track down their father, Lee Harvey is wearing a plain grey vest. In alternating shots the vest changes to one with black edging, and then back to plain grey again.
In the scene where Irene and Charlie run after the train there are several discontinuities: 1) The warning cross disappears in the shot where the last car passes. 2) In this shot the last car looks much higher than when Irene jumps on. 3) The sun direction changes.
When Dickie is in Hank's and Irene's train cabin, Irene hits him over the head and he lands on top of Hank. You can see his head is behind Hanks shoulder, but when Hank wakes up Dicky's head is next to Hanks.
When Charlie is taking Irene back to New York on his motorcycle they come across a supposed dead cow in the middle of the road, which by the way you could totally tell is fake. Charlie pulls out his gun and shoots the cow a few times then throws his gun off to his right way off the screen. Next screen shot the gun is right next to him.
Just notice that in the clip at the very, very end of the movie, when Whitey says he thinks he's found the missing thumb, he ducks under without the hose in his mouth. But in the water, it's in. Then when he comes back out, it's out again.
In the scene where both Jim's characters are beating each other at the wheel of this red convertible, bad Jim throws good Jim out of the car which was doing some 30/40 mph in a straight line. In the next shot Jim is seen chasing the car on foot: the convertible is now doing no more than 7/10 mph and it's descending a hill after a sharp right-hand corner.
This happens a lot in the movie but specifically... When Charlie is shooting the cow, the wide shots with the bike are really sunny, but in the close ups (fingers in the nose) it is overcast or studio lighting.
Irene's hair moves back and forth between behind and in front of her right shoulder in the scene where she tells the police officer about her accident. It undergoes further changes when she talks to Dickie on the phone.
When Charlie/Hank and Irene arrive at the train station in Rhode Island. Charlie and Hank are having a "fight", during this fight Hank unzips his pants to wiggle his "thing" at a group of ladies sitting on a bench. Immediately after that he falls to the ground and his pants are zipped.
In the scene where Hank comes crashing into the building with Dick's car, the driver's side headlight is intact. They show the people in the building, and when the shot returns to the car, the headlight is dangling from its socket.
In the scene where Charlie is being chased through the train station and gets shot in the arm look out for a boy in the train station with a green top because immediately after he exits the station the boy is sitting on a bench outside.
During the scene where Charlie is being bandaged after having his thumb shot off, the RIPD police cars have blue light bars. During the scene of the road block for Irene, the RIPD police cars have red light bars.
When the cow moves again after Charlie shot it in the head several times, he throws the gun out of camera shot. When the camera shows Charlie wrestling with the cow, the gun mysteriously appears next to the cow's head.
When Charlie is talking with the little girl, as she says her line "My dad says you're a joke..." two people can be seen walking past behind Charlie. We cut to a close-up of Charlie sighing in exasperation, and the same two people walk past behind him again.
In the last scene when looking for Charlie's thumb in the water, Whitey puts his head in the water (the snorkel is not in his mouth). From the underwater camera, the snorkel is in Whitey's mouth. When Whitey lifts his from the water, the snorkel once again is not in his mouth.
Near the end of the film, we see Irene and her ex-boss on a deteriorated wooden bridge. The gaps in the bridge's planking are spanned by two parallel boards. However, moments later when Charlie crosses the same bridge, the gaps are spanned only by single planks.
The length of the white picket fence, between Charlie's house and his rude neighbors, changes several times throughout the movie. Sometimes it appears to reach close to the road, other times it is more flush with the houses.
When Charlie first loads up Irene on the back of his motorcycle and takes off, the first highway shot bounces and the front wheel of the motorcycle can be seen clearly mot even turning, indicating the bike is on a trailer. The vast majority of cycle shots make the bike look this same way, like its on a trailer.
Scenes of Charlie/Hank's house were shot in the Bonnet Shores neighborhood, in the town of Narragansett. At one point, Charlie/Hank leaves his house for a drive (I think to work). The very next shot shows him driving west over the Newport Bridge, which is the incorrect direction if he's leaving from Narragansett.
Before they make the first train stop, the train conductor announces they will be stopping at Providence, Rhode Island. But, the scene is filmed in Burlington, Vermont at One Main Street's train station. You can see a sign that says "Burlington" along with the distinctive addresses seen and license plates.
Charlie's diagnosis of "advanced delusionary schizophrenia with involuntary narcissistic rage" is incorrect. Schizophrenia causes delusions and hallucinations with paranoia. Many people used to believe that schizophrenia resulted in multiple personalities, but this is not the case. He should have been diagnosed with dissociative identity disorder (also known as multiple personality disorder). Further, there is no medication used to treat multiple personalities, although some medications can be used for other symptoms (such as anxiety and depression) that accompany the condition. Treatment of DID involves years of psychotherapy - the disorder cannot be cured by taking a pill as portrayed in the film.
The police are informed that Charlie and Irene are 100 miles away. As they board a police helicopter one of the cops tells them they can be there in 15 minutes tops. This means that the helicopter will be traveling at 400 mph. Police helicopters max out at about 130 mph.
One only gets a "milk mustache" from drinking out of a broad-rimmed glass or cup (as opposed to sipping with closed lips from a narrow-bodied straw or bottle), so Charlie/Hank would not have gotten milk on his upper lip merely from his "localized suckling" at Ms. Buxom's titty.
Much of this movie was filmed in the Burlington and Middlebury areas in Vermont. Therefore, there are a lot of inconsistencies with vehicle plates and identifying characteristics of things like particular state trooper uniforms/cars/etc. And yes, the abandoned bridge/railroad trestle/etc. is actually the pedestrian bridge over the Otter Creek in downtown Middlebury.
After the encounter with Chrysler Convertible Dude, the road along which Charlie, Irene, and Whitey are travelling is just an ordinary two-lane highway, so there is no way that C.C. Dude could have been tootling alongside them for the flaming hat to be tossed over into his passenger's seat.
Just after Hank trashes the car in the handicapped space at the convenience store, only Hank and Irene are in the car driving away. Whitey is missing. A couple of shots later, he is again in the back seat.
