Goofs

Several times during the movie, Simon Phoenix's shoulder pads (one side resembles an ATV tire) switch sides. Not only that, but Phoenix has two different color eyes - left blue and right brown - which also switch sides.

Spartan's body position and mouth change several times while he is supposedly frozen. Before he freezes, his mouth is closed and his body turned. When he freezes, his mouth is open and his hands placed facing up (showing surprise, etc.). The levels of surprise shown in the mouth and body position change throughout.

In the beginning when Simon finishes using the dagger to puncture the gasoline barrels, he lays it back on the table and it is dry. You can see the gasoline spraying all over as he jabs each plastic barrel. He would also have the gasoline on his hands when lighting the cigarette.

During the car chase, Phoenix fires his MP5 out of the rear window of the police car. But when Spartan jumps onto the roof, the rear window is evidently unbroken.

In one scene Spartan changes seats with Huxley in a police car. When Spartan sits on the driver's seat Huxley can be clearly seen in the background. But after they switched their seats Spartan doesn't appear behind her.

Towards the beginning, when gasoline is everywhere and Simon holds the torch close to the ground, it should ignite. It's the fumes that ignite, not the gasoline itself.

Huxley states that because salt is harmful, it has been made illegal. In truth, the minimum requirement of sodium necessary to sustain life has been estimated at 500 mg per day; in other words, without salt, you would die. If you're active and therefore perspire a lot (as is perhaps the case with John Spartan), your need for salt increases significantly.

At the beginning of Spartan's defrosting, the computer voice announces, "pulmonary activity approaching normal." He is still frozen in solid ice at this point and cannot possibly be breathing.

In the climactic cryoprison fight, when John Spartan is trapped in the metal grabber, he freezes the metal so that he can break it and free himself. In fact, if the metal was frozen to such an extreme that it becomes that brittle, it would have caused severe cold burns to his skin.

In one scene Simon Phoenix kicks in the windshield of a car and it shatters like a drinking glass.

In the beginning of the movie, a stockpile of C4 catches fire, and thus blows the whole building up. C4 only can be detonated by a detonation charge or blasting cap which is just a smaller explosive. If it catches fire, it burns slowly.

This is true of C4, however, there were no details to describe, and no one suggested, the C4 was only detonated by the fire. It is reasonable to believe Phoenix detonated them by other means. Spartan stated to his captain "he rigged the place to blow". The complete destruction of the building in successive detonations is a firm indicator the charges were strategically placed throughout, and anyone with that skill would not rely on a gasoline fire for detonation.

When the computer is responding to the first Code 187s, it is heard to say "Last recorded offense: September 25, 2010," which in the movie would have been 22 years previously. However, when Spartan is first thawed, Garcia tells him that "There have been no deaths of unnatural causes in San Angeles in the last 16 years." His math is off.

It is stated that the last recorded offense of "187" (which is the actual current California Penal Code section for murder), was 22 years previous. It was also stated "There have been no deaths of unnatural causes in San Angeles in the last 16 years." Both can be simultaneously correct. Death by unnatural causes does not assume murder, and they are not the same. It is possible, and consistent with the story line, there were no murders for 22 years, and there were no unnatural deaths for 16 years. There are countless possibilities of death, including homicide, that are not murder. For example, if a person choked on a cherry pit and died, it would be unnatural, but not murder. As well, industrial accidents resulting in death occur frequently, and are not murder. It's hard to believe that any society could continue for 16 years with no unnatural deaths, but improbability does not equal impossibility.

Both Spartan and Phoenix receive verbal morality tickets throughout the film the latter's tickets are issued without giving a name due to his lack of a code chip. By that logic he shouldn't receive a fine at all because in addition to identification the chip is also responsible for all monetary transactions meaning any fine incurred couldn't be enforced.

This is a futuristic computer-operated system in a world where everyone is Lo-Jacked, and no one has reason to believe otherwise. Phoenix effected his own premature release, and was not subject to the "normal" method, which certainly would have included the implant. It isn't unreasonable to believe the computer system automatically triggers on Verbal Morality Code words or phrases, and responds even when it is unclear who is the offender. It would be reasonable for the computer to simply respond as programmed with, "[null], you are fined one credit for violation of the verbal morality code", and print the ticket with no name.

Firearms on display in a real museum would be deactivated so they wouldn't work, and no ammunition would be available. The guns in the movie are all working and surrounded by live ammunition.

That's deliberate. In a future society so safe that even the police don't carry firearms, they wouldn't consider deactivation necessary.

When introduced, Edward Friendly is all about "I like to think, I like to read. I'm into freedom of speech and freedom of choice." Yet, once the Cocteau regime is overthrown, he tells Associate Bob to change his attire and hairstyle.

This is sarcasm on Friendly's part. Associate Bob was so over the top that Friendly was trying to sarcastically tell him that he looks ridiculous.

When Phoenix falls through the glass at the museum into the LA exhibit, you can see him sliding down a visible safety rope. His feet are even in the position to be sliding down the rope.

Even though the audio dubbing and logos for Taco Bell were changed to Pizza Hut in post-production in some versions of the movie, the editors missed some. The original logo for Taco Bell can still be seen on the windows of the restaurant when Lenina and John go out to dinner. The sign outside clearly says Pizza Hut, while the windows show the Taco Bell logo.

Very obvious stunt doubles used in distant shots for Stallone and Snipes while fighting around the old car during their second bout.

When Spartan's car crashes through the police station sign the glass explodes before the car hits it, in addition the charge fails to break the "A" panel.

When Huxley pulls up Simon Phoenix's rehabilitation program in her car, the profile photo is not that of Wesley Snipes, but of someone else made up to be the Simon Phoenix character.

When Simon is shooting at John Spartan during the car chase scene, he shoots out of the back of the car. There is no sound of the rear window glass breaking, and it never shows him breaking the rear window previously.

When Phoenix punches (and kicks) the glass to try to take the guns, the display glass sounded like it was plastic, but when he threw the guard into the display glass, it shattered, like it really was glass.

When Spartan drives for the first time with Huxley, Spartan says "I come out of cryoprison and I'm Betsy F***ing Ross" but he is not given a credit fine for swearing.

When Spartan buys a burger from the Scraps he is asked how he will pay for it. He then offers Huxley's watch in exchange. Since it was established early in the movie that all monetary transactions are done through codes (which Scraps lack), the Scraps would have no way of trading the watch for cash making the watch worthless to them.

In the opening sequence, when Simon Phoenix informs John Spartan that the latter is standing in gasoline, Spartan reacts surprised, as if he thought it was water or something. That amount of gasoline would give off quite a strong smell, making it obvious that it was gasoline or a similar flammable liquid. The stack of leaking gasoline drums a few metres away is another giveaway. It's hard to believe John Spartan would have failed to notice what he was standing in.

Zachary Lamb and Chief Earl are roughly the same age but Earl seems to have no recollection of anything that happened in the twentieth century or before the "Big one of 2010" but Lamb knows all about Simon Phoenix even saying that he was on Unsolved Mysteries a show that was syndicated nationwide as well as the news that Phoenix declared his own kingdom in South LA.

After "having sex" with Lenina Huxley, John Spartan returns to his apartment, picks up a ball of yarn, and starts winding the yarn around his hand and elbow to create a skein, which makes no sense. Yarn which is sold in skeins is often wound into balls prior to use to avoid tangles, so Spartan's ball of yarn is ready to go; winding it into skein serves no purpose, other than increasing the likelihood of potential tangles, which any serious knitter would want to avoid.

When pursuing Simon Phoenix into the sewer, Lenina, climbing down the ladder, comments about how filthy the surroundings are. She then runs her gloved hands through her hair.

When Simon Phoenix is in the museum querying the computer about the "linear accelerator gun", the computer voice states that the gun achieves fusion in 2.6 minutes. However, the computer screen indicates "fission time 2.6 minutes" on the diagram of the weapon.
