Crew or equipment visible: The camera/crew occasionally reflected in Charlie's motorcycle, especially during the introduction.
Continuity: Charlie/Hank's pants are zipped up and belt buckled after he flips himself to further stop "flashing" people.
Continuity: Irene removes her left shoe twice after Charlie gets the sodas.
Continuity: 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.
Revealing mistakes: When Whitey reads the note left by Irene and Charlie on the car Scooter is reflected on the car waiting and then moving onto the set.
Boom mic visible: When Charlie opens the door of the car for Irene near the end the boom mic (or a support cable) is reflected in the wing mirror.
Crew or equipment visible: When Charlie climbs back into the red car you can see the reflection of the camera on the hood. You can also see the shadow of the 4x4 used to tow the car with the equipment loaded in the back.
Continuity: 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.
Revealing mistakes: When Charlie (as Hank) opens the car door after crashing the car through the barber shop window, the wall of the set wobbles as the car door nudges it.
Continuity: The train's locomotive changes from an F40PH to a P42 Genesis in the train scene (the one they sleep in).
Continuity: 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.
Continuity: When Charlie is chasing Irene on the bridge the bullet hole in his jacket is gone. In the close up shot at the end of the bridge it's back.
Continuity: After Whitey tells Charlie his secret, Charlie explains it to Irene. In this scene, his chin looks larger underneath the bandages. In the next scene when they lie on bed, his chin looks normal again.
Continuity: The bandage on Charlie's chin is taped differently in many scenes.
Anachronisms: On the beach in the 1982 prologue, the two are drinking Budweiser beer out of late 1990's bottles that came out of a late 1990's six pack.
Continuity: Partington is alternately addressed as "Captain" and "Colonel" throughout the film.
Continuity: When Charlie stops to move the "dead" cow from the road, he turns off the motorcycle (and the headlight). After he shoots the cow, the headlight is back on.
Revealing mistakes: The cow that Charlie tries to choke is obviously animatronic. When he is trying to choke it he moves back and forth and the whole cow moves back and forth, as if a solid unit.
Continuity: When Irene and Charlie are trying to get on the train, the sunlight direction changes.
Continuity: During the first shot of the chicken in the officer, we see live chickens in the background. During the next shot, almost instantaneously, they are gone.
Crew or equipment visible: Reflected in the side of the SWAT van that pulls out of the motel parking lot.
Boom mic visible: Shadow on ground when entering Ben & Jerry's.
Continuity: 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.
Continuity: The position of the cigarette in the barber's hand when Hank drives in the barbershop.
Continuity: 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.
Anachronisms: 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.
Revealing mistakes: 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.
Anachronisms: 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.
Continuity: 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.
Revealing mistakes: When Charlie gets his thumb shot at the end of the film, he shouts out and raises the bloody thumb. In one shot it is obvious that he has folded the thumb.
Errors in geography: 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.
Errors made by characters (possibly deliberate errors by the filmmakers): 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.
Factual errors: Schizophrenia and dissociative identity disorder/multiple personality disorder are two distinctively different mental afflictions. They are portrayed as synonymous in the movie.
Continuity: In the beginning of the movie when Charlie pulls into his driveway you can see that the two trees on either side of his front door are tall. When the movie gets to the point where Charlie is leaving for work and the boys are building an airplane the trees are short. When Charlie gets back from work on the day that Hank appears the trees are tall again.
Errors made by characters (possibly deliberate errors by the filmmakers): 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.
Errors in geography: 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.
Continuity: 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.
Boom mic visible: When Irene and Charlie are waiting outside for a train after Charlie calls his sons, the boom mic is reflected in Irene's sunglasses when they are sat on the bench.
Factual errors: When Charlie/Hank and Irene are discussing the items they found in the trunk of the car they stole from Lieutenant Gerke, they mention finding rope, a shovel and a bag of lime, coming to the conclusion that he intended to kill them and bury the bodies. Lime is not typically used in the disposing of bodies, however a chemical known as lye is.
Revealing mistakes: New York State Troopers uniforms are not blue and do not wear badges, as seen in the movie. They wear gray uniforms without a badge.
Revealing mistakes: New York State Police Cars do not resemble those present in this movie.
