Richard Kimble has a stand-off at the end of the tunnel with U.S. Marshal Samuel Gerard. He then jumps from the tunnel on the dam's face into the water below. In the exterior shots of the dam afterwards, it is clear that there are no tunnels coming through the face of the dam (the water flows over the top.)
During the emergency room scene just before Dr Kimble diagnoses the young boys condition you can see the boom mic in the reflection of the medicine cabinet when one of the male nurses says "is there a doctor in here?"
One time when Kimble is fleeing the U.S. Marshals, he is shot at (but not hit as the glass is bulletproof). U.S. Marshals do not have the authority to shoot a man who did not pose a capital threat to them.
When Gerard interviews Nichols in his office, he says that Nichols and Kimble graduated from medical school together, "class of 1973". However, the picture he is looking at on the wall reads "University of Chicago Interns '72-73", which means that Nichols and Kimble would have graduated medical school in 1972.
When Kimble is checking out the apartment, the landlady is speaking to her son in Polish and asks him a question. The son replies "Da" which means "Yes" Russian, while the actual Polish word for "Yes" is "Tak".
When Kimble calls Walter from the pay phone, the bell on the bridge gives its last ring just after his first line, "Walter, this is Richard." When Gerard plays back the tape of the call, the bell rings 4 or 5 more times after that.
During the bus wreck scene, when the bus is driving down the road and crashing, there is a double yellow line and a guard rail. A few minutes later, the same road is line with police cars and fire trucks with no line or rail.
When Kimble and Gerard are running through the tunnels, just before Kimble jumps out of the tunnel into the dam, Kimble jumps down into a undisturbed pool of water. Seconds later, when Gerard jumps into the same pool of water, it is still undisturbed, although Kimble just jumped and ran through it.
Kimble hides from the hospital orderly behind the door leading to the bathroom. Kimble's hand is still visible in the mirror as the orderly walks in and out. Kimble's hands change position without him actually moving them, due to a slight cut, once the orderly leaves.
(Possibly only in pan and scan version) When Gerard is looking over the crime scene photos of Kimble's house taped to his window, you can see Kimble's fake hospital ID tacked on the wall, despite the ID hadn't even been made yet.
When being transported in the prison bus Kimble is fully cuffed at the waist, but when the bus is rolling down the embankment his right arm is free and over his head. When he says "unlock me" and the guard throws him the keys, he is still fully chained at the waist.
After the bus crashes, Kimble unlocks his hands and throws the keys onto the floor in front of Copeland. Two shots later when Copeland grabs the keys, they are lying in a different position on the floor.
When Kimble calls his lawyer on the pay phone, initially you see an "Illinois Bell" banner on top of the payphone hut. When the scene cuts to the lawyer then back to Kimble, these banner areas are blank.
As Kimble is climbing out of the bus window his leg shackles appear to have disappeared yet in the very next scene where he is seen running from the derailed and fast approaching locomotive, he clearly has them back on.
After Kimble shaves in the hospital he comes across a patient coming out of an ambulance. The man tries to say "it's Kimble" before being carted away. Kimble starts to point with his right hand, and because of good editing, in the next scene it looks like the same hand but in actuality it's his other hand he is now pointing with.
When Kimble is taken away by detectives after his wife's murder, he thinks back to events which took place earlier that evening, including the moment when Charles Nichols introduced him to Alec Lentz. Later in the movie when Kimble thinks back to that moment, after breaking into Frederick Sykes' house and seeing Lentz in a photo, the words and actions of Nichols and Lentz are slightly different to what was seen earlier in the movie.
After Gerard spots Kimball at the jail, Kimball runs down two flights of stairs and detours down a hallway to an opposite flight of stairs. Kimball changes his pace to walking fast and passes by the elevators. It takes 14 seconds after this for Gerard to notice that Kimball is not on the same stairs, yet the scene shows Kimball just past the elevators when he should have been long gone.
When the prison bus is rolling down the hill it comes to rest up against a tree and is parallel with the slope. As the train is approaching, a shot of the bus up ahead shows the bus sitting upright across the tracks which would make it perpendicular to the slope it just rolled down off from, not parallel.
Just after Kimble fights with Sykes on the EL train, he takes both Sykes' and the transit cops guns. Sykes' gun gets placed into his right pocket, and the transit cops into his left. However when Kimble dumps the guns into the mailbox, Sykes' is in his left and the cops is in the right.
As the train wreckage comes to rest Kimble is hiding under a
small trestle bridge. A shot up at the wreckage shows a crew member's face above the trestle. This error was corrected for the 2001 DVD release of the film, after Andrew Davis noticed it. The crew member reappears on the Blu-Ray disc version of the film.
Moving shadows, possible that of a crew members hand, can be seen on the elevator interior wall behind Dr. Kimble as he exits the elevator on the 5th floor laundry room (after the fall from the skylight).
The Marshals tracked Dr. Kimble from the phone call at the one armed man's house and said that his address was 10256 S. Saint Lawrence. The Marshals went in and come out of 11217 S. Saint Lawrence. Also, the house that the one armed man went into was on the other side of the street.
Although the movie is set in Chicago, many of the scenes show large hills and mountains. Illinois is flat through most of the state, but in the begining scenes in Southern Illinois, the area is rugged and hilly. (The scenes were filmed in North Carolina).
Kimble and Nichols leave the Grand Ballroom at the Hilton Towers and go next door to the presidential suite. The ballroom is on the second floor of the Hilton, while the presidential suite is on the top floor. Next door to the Grand Ballroom is the International Ballroom.
While headed on the train with the one armed man, "his stop" and a variety of lines include a destination as the El's Balbo Stop. Though Balbo is an avenue which travels in and around the famous Grant Park, it is not a stop nor has ever been one on the train system.(In fact, most of it would have been initially underwater)
When Kimble boards the "Kimball" Brown Line train, he ends up headed south out of the loop on a Green Line train (the Aerial shot shows the south Loop exit S-Curve). The Brown Line only heads north out of the Loop.
A television news montage is seen in an electronics store containing video of Kimble from earlier in the film and includes a scene from Kimble's sentencing hearing. Since cameras are not permitted in Illinois courtrooms, the only "image" from any of the court proceedings available to the media would have been those created by courtroom sketch artists.
In a closeup of a Chicago Sun-Times paper dated THURSDAY, MARCH 18, 1993 the main article highlights "Kimble in Chicago: Fugitive Escapes Downtown Pursuit". To the left of the article is a blurb titled "Fan Hits $1 Million Bull's-Eye" about the Bulls fan Don Calhoun that hit a half court shot for $1 Million. The photo and date indicate this happened on March 17, 1993 when in fact Don hit the shot on April 14th, 1993.
When the ambulance Kimble stole is seen, as Gerard gets on the helicopter, the engine in just starting up yet the helicopter is in the air just a few seconds later, way too fast to allow it complete the startup process and start flying.
Gerard states that he's taking over the local sheriff's investigation and he's from the United States Marshals Office, 5th District Northern Illinois. All of Illinois as well as Indiana and Wisconsin are in the 7th district.
When Kimble is making the call, the PA announcement for an El train is overheard. While PA announcements are now made only inside the train, in the early 1990s they were clearly audible in the station (maybe more so than in the train), and even in the nearby streets.
In the laundry room at Hilton Towers, a cart is clearly marked "Palmer House", a different Chicago hotel. However, since they are both Hiltons and near each other, it's not unlikely they would share some back-room equipment.
Kimble dyes his hair black in one scene and then in another scene his hair is the same old color from the beginning of the movie. However, it's entirely possible (even likely) that Richard purchased the kind of temporary dye that washes out within a few weeks. Since the scenes take place over the course of several months, it's not at all unlikely that the scene in which Richard's hair is again its natural color occurs a few weeks after the last scene in which he has black hair.
When Kimble is initially questioned by CPD detectives after the murder of his wife, he challenges them by saying, "You find this man." Later in the movie, flashbacks incorrectly quote him as saying, "You find that man." However, this is to show different perspectives of the same scene.
The prison guard is asked, "Just for the record, these three are dead, right?" about the prisoners, to which he replies, "Yes." He then says he doesn't think that Kimble got out. However, he only saw the prisoner who was foaming at the mouth die (he shot him). He had no knowledge that the other two besides Kimble were dead.
When the elevator with Kimble and Nichols reaches the laundry room, the hole in the roof shows the elevator cables. The image is decidedly grainy. It's obviously a pre-recorded image, and was then composited onto the scene at a later date.
In the scene on the laundry room floor when Kimble sticks his arm through the closing elevator door to open it up again so he can get out, if you look at the door, you'll see blood smears, possibly from other takes of the same scene since Kimble has blood on that hand.
While Samuel Gerard is searching for Richard Kimble among the people at the St. Patrick's Day parade, you can clearly hear a person shout out, "Hey Tommy! Woo!", likely directed at actor Tommy Lee Jones.
When Kimball crawls out from under the bridge after being chased by the derailed locomotive 536, the 536 has no traction motors on its wheels. Without traction motors a locomotive cannot move on its own, let alone pull a train. Obliviously the derailing train was being pushed from the rear end.
The goof items below may give away important plot points.
At the end of the movie, when Gerard brings Kimble out of the hotel, there is a large crowd of reporters asking questions. They follow them right to the car and when Kimble gets in the car, it's clear that the window is open, however, when Gerard and Kimble are in the car, you can no longer hear the sound of the crowd just outside of it.
In a newspaper article regarding the St. Patrick's Day parade, a sub-headline says "Fugitive Escapes Downtown Pursuit" but the text of the article says "Kimble was apprehended after an extensive chase by Police and several bystanders," even though Kimble escaped.
When Kimble is confronting Nichols in the Hilton ballroom, the rear shot shows Kimble extends his arm to the right motioning to Nichols to leave the room to the right. When the shot then goes to the front, his arm is still at his side.
At the end of the movie, when Richard is being taken out of the Hilton towers, the trees across the street from the hotel are in full bloom. However, there are no green leaves on the trees in mid-March in Chicago.
When Dr Charles Nichols is hit from behind by Kimble in the laundry at the end of the movie, the gun in Nichols' hand is resting on his other hand, and he is obviously unconscious. However, when Sam Gerard goes to disarm him, the gun is lying flat on the ground.
When Kimble and Nichols are fighting past the ballroom, Nichols slams Kimble with a quality hardwood chair that shatters on impact. Chairs of this construction would never disintegrate so easily after impact with a human body.
