Crew or equipment visible: When Max sees the security guard at the office building he runs around to another door. The cameraman is visible in the glare of the building running next to Max.
Continuity: When the taxi cab crashes, Vincent (or a dummy that looks like Vincent) is clearly visible upside-down in his seat. But it the next shot, he's laying on his back.
Continuity: When Max crashes the cab, he passes the water barrels. In the next shot, he crashes into them.
Continuity: The rubber bands that hold Max's picture postcard to the visor are sometimes smooth and other times twisted, even though he hasn't removed the postcard.
Factual errors: When the two LAPD officers pull Max over, the black officer is sporting a goatee. Per LAPD regulations, no uniformed officers may have a goatee.
Continuity: The smashed windshield is inconsistently broken throughout the film.
Continuity: The "Metro" sign isn't on the wall when Max and Annie run to it, but it appears when Vincent chases after the two.
Continuity: When Annie and Max are running from Vincent, they come to the subway platform. The train they board is marked for the "M" platform, although the platform they're on is marked "L".
Continuity: After Max and Vincent leave the Fever Nightclub, Max crashes his taxi into two parked cars. In the first shot of the front of the car after the crash the taxi appears to have no damage at all, the following shot the left front light is broken and there's damage to the side of the taxi. In the next shot, the damage is gone again.
Crew or equipment visible: When the taxi crashes, hidden equipment is visible next to the parked cars, but is removed after the crash.
Continuity: After Vincent was shot for the first time by Max, his jacket was torn at the shoulder. In the next scene there is no tear.
Continuity: In some shoots during the subway/train scenes Vincent is not wearing a belt.
Revealing mistakes: When Max and Vincent load the first corpse in the trunk, the "corpse" is holding Max by the wrists as well.
Errors in geography: The lawyer Vincent shoots is supposed to live on Fountain Avenue in West Hollywood. The view from his condo is downtown Los Angeles - about 12 miles from the given address
Continuity: Right before Max crashes the car, they pass by Staples Center in Los Angeles and it is green and red (they change it to green and red during the holiday season). Then when you see Staples Center throughout the rest of the movie (which occurs on the same night) it is back to the original colors of blue and red.
Audio/visual unsynchronized: In the jazz club, Daniel removes the trumpet from his mouth before the final note he was "playing" has finished on the soundtrack.
Continuity: When Vincent is offering Max the money to hire the cab for the night he puts his hand up on the back seat but in the next shot Vincent's hand is not there.
Continuity: At the catwalk scene, right after Max tosses out the briefcase, Vincent is holding his gun with his right hand, and passes it to his left hand. At the next shot, he's holding the gun with his right hand again.
Continuity: When the characters enter the hospital elevator on the main floor, it has a telescopic door, but at the 3rd and 5th floors the door opens centrally.
Continuity: When Annie knocks on the passenger-side window to give Max her card, he rolls the window all the way down, but when she hands him the card, it is only half-way down.
Revealing mistakes: In the hospital morgue scene, the eyes of the second corpse (rich guy killed in penthouse apartment/Vincent's second hit) move in a close-up of his head. Moreover, the 'corpse' is breathing.
Continuity: After the shootout in the subway, Max has his glasses on. Then when Max is shown sitting across from Vincent they're off and he puts them on. Then when they show him get off the subway with Annie, he doesn't have glasses on again.
Audio/visual unsynchronized: After the final taxi crash when the cop is trying to put the handcuffs on Max you hear the locking sound effect of the first handcuff going on, but the cop never gets the first handcuff on.
Errors in geography: After Max picks up Annie at LAX she suggests taking La Brea Ave to 6th St and heading downtown. Max advises against this, citing that traffic gets heavy on La Brea above (north of) Santa Monica Blvd. This is irrelevant because 6th street is about two miles south of Santa Monica Blvd and if they were to have taken her route they would have turned onto sixth long before Santa Monica Blvd would have come up.
Continuity: When they enter the elevator in the hospital, and Vincent asks what floor, in one shot he is pressing the buttons with his right hand, but when they show the buttons pressed, it is his left hand (as the thumb is pointing down).
Miscellaneous: While Annie is riding in Max's cab, Max turns on the radio and we hear the song "Hands of Time" by Groove Armada. Annie comments: "Oh, you like the classics?" While sounding somewhat like classic '70s Motown, this song did not come out until about a year before the movie was made, which, strictly speaking, hardly makes it a classic. Also, Max makes a reference to "woodwinds" (which the song contains none of) implying that they originally intended to use a more classical piece.
Crew or equipment visible: While driving on a near-deserted road (going to Fever) what appears to be the flashing red and blue lights of a police car (presumably escorting the production vehicles) can be seen reflected in the cab's window.
Continuity: When Annie gets into the cab at the start, she gets in and sits on the left hand side, yet throughout the rest of the cab ride, she is on the right hand side (directions as per facing destination).
Continuity: When Vincent checks Annie's desk, the telephone receiver changes from being aside of the phone to hanged up in the reverse angle shot.
Factual errors: During the gunfight at the nightclub, Vincent fires at least seventeen shots from his gun before reloading, even though the USP he uses only holds fourteen.
Crew or equipment visible: (At 1:19:13) Light fixture visible in Club Fever.
Revealing mistakes: When Vincent sees the light for the phone line in the U.S. Attorney's Office, the label is for the 16th floor storage room, not "Library" (where Annie is) which is right next to it.
Continuity: After the body falls on top of the cab, starting when we see Vincent washing off the roof, the "Taxi" and yellow ad signs ate repaired with gaffer tape. We never saw them broken nor saw them repaired.
