Event Horizon (1997) Poster

Goofs

Factual errors 

"Liberate tutemet" is wrong in Latin. "Liberate" is 2nd person PLURAL imperative, "tutemet" is an emphatic 2nd person SINGULAR pronoun. The correct version would have been "liberate vos" or "liberate vosmet". "Tutemet" (which is a very rare form) is also wrongly nominative: an accusative is needed in the sentence for the object of the verb "liberate".

Audio/visual unsynchronised 

In the scene where Justin is touched by something in the black gateway, you hear him say "Oh, shit!" but his mouth never moves.

When Cooper is comforting Stark at the end, Cooper's words clearly do not match his lip movements.

When the crew first approach the Event Horizon in space, they nearly hit the ship and Dr. Weir yells "We're gonna hit!" but his mouth never moves.

Continuity 

The Lewis and Clarke crew enters stasis on the way to Neptune, made necessary because of the "30 Gs of acceleration" they will endure for the trip. When they arrive at Neptune, however, there are coffee cups and other debris on the tabletop, loose chairs, etc., in the same position as they were before the trip. This is not consistent with sudden and severe acceleration.
Upon first entering the Event Horizon, Captain Miller comments on how the ship is a "deep freeze" and how there are ice crystals everywhere. Immediately after this, we see a water bottle floating around with liquid sloshing inside it.
The rope or wire which Captain Miller uses to pull himself through the doorway when the spacecraft's window is broken disappears when he props it open to save Lt. Stark.

Despite being washed away in a flood of bloody water, in the following scenes Stark is mostly dry and whilst bloody is a lot cleaner than would be likely.

On Captain Miller's shirt, his first initials are shown as being S.A. whereas on the door to his bunk, they are shown as being S.J.

Just after helping Weir to his feet and as he turns away, you can see that D.J's shorts are completely dry on his backside, despite being in a tank of liquid for the last 56 days and being visibly dripping wet from the front.

Just before Miller jumps through the closing door escape the fire in the 'meat-grinder', there are several very short cuts from various angles. During the very last cut which shows the fire coming head-on towards the camera, the meat-grinder is not revolving. Throughout the entire film, apart from that moment, the grinder is consistently turning.

Studio space/backs of other sets briefly visible through holes in the "meat grinder" tunnel when the fire races through it.

Factual errors 

When Justin is ejected into outer space, his veins immediately start to burst and bleed heavily. This isn't very likely to happen in the short time that he is exposed to the vacuum of space. Parts of the body will probably start to bulge due to the lack of atmospheric pressure, and there will probably be some subcutaneous bleeding from ruptured blood vessels, but the human skin is thought to be resilient enough to stay intact. Also, the blood that leaves his body remains liquid; in reality, it would boil and evaporate instantly due to the lack of pressure. Not everything about the scene is unrealistic: the fact that he remained conscious is probably correct (most adults would remain conscious for 10-20 seconds), as well as the fact that he does not freeze (although deep space is extremely cold, the lack of gas molecules makes it difficult for body heat to leave the body).
Sounds are often heard in the outer space throughout the movie despite there supposedly being no medium for sound to travel in.
When Dr. Weir plays the record of the emergency signal containing the "Liberate me" bit, D.J. says that he can't make out the rest of the message, but Dr. Weir always stops the tape immediately after Liberate Me has been spoken, so D.J. wouldn't have been able to hear any other part of the message to begin with.
Blood would have dried in seven years' time. Liquid blood droplets would be nearly spherical due to surface tension, like the coolant.

As the Lewis and Clarke approaches the Event Horizon somewhere near Neptune, it goes trough multiple cloud formations. However, all later scenes happen in zero gravity making the presence of any atmosphere impossible at that particular level.

Miller's rank is "captain", as shown by the four-stripe insignia on the shoulders of his jumpsuit. Yet his leather jacket shows two silver bars on the shoulders, which is the insignia for "captain" in land and air services, a much lower rank. As the service shown in the film is modeled on the U.S. Coast Guard, Miller's jacket should show a captain's silver eagle.

Although the ship is referred to as a 'deep freeze,' twice we see a bottle of sloshing water floating about the Event Horizon, at the very beginning of the movie, and just before the rescue crew boards.

Miscellaneous 

The Omega Speedmaster wristwatch floating around the Event Horizon at the start of the movie can be heard ticking as is passes. However the Speedmaster has a manually-wound mechanism with a power reserve of 48hrs; if the ship had been empty for seven years the watch would have stopped ticking long ago.

There really is no reason to subject a ship to 30gs to reach maximum velocity needed to get to Neptune unless you absolutely had to. Using linear acceleration, you can accelerate the ship and in 24 hours would reach the same speed, all the while never exceeding 1 to 2 gs the whole time and only spending one extra day to get there.

Incorrectly regarded as goofs 

As has already been mentioned in one of the other goofs, there is no atmosphere in space and even thought the temperature was at absolute zero, body heat would not be rapidly lost: no atmosphere means there's nothing to conduct the heat away nor to radiate heat away. The drifting crew members would not turn into space popsicles and limbs would not shatter a la Terminator 2.

This is not quite correct. There is still another way to lose heat: By radiation. It is slower than conducting, but of course, after a long time, the bodies would exactly be frozen like depicted in the movie.

Plot holes 

There is no gravity on the Event Horizon. The movie makes a point of showing magnetic boots keeping everyone on the floor. Yet when Justin is sucked into the "heart of the ship", the resulting shock wave hits Capt Miller and he is thrown against a wall. He then falls to the floor, instead of floating in the air like the rest of the loose debris on the ship.
Why would crew members be smoking on their spaceship. It's an enclosed, oxygen rich environment that is propelled by extremely flammable liquids.

At 55min Starck says that CO2 levels will become toxic in 4hours from that moment. Furthermore, they brought CO2 scrubbers back to the Lewis&Clark and then that ship exploded. So how did the rest of the crew survive in a toxic environment and without the scrubbers?

It was said the Event Horizon is in a decaying orbit however it is obvious they are in the troposphere of Neptune (evidence by the lightning and clouds) and therefore no longer in orbit and should be experiencing gravity that of Earth (Neptune's gravity is 110% of Earth). Therefore zero-gravity should not exist where the Event Horizon is locate, furthermore, the Event Horizon should be falling to the surface of Neptune.

The highly trained aerospace officers understand none of the theory behind space travel. Captain Miller explains how his gravity drive works by folding the ends of a piece of paper together (a pin-up, of course) and poking a pencil through both sheets.

Revealing mistakes 

Near the end, when Cooper watches the "blood" flowing above the ceiling lights, the front of the flow does not change shape at all and also, just before the camera changes, briefly jumps backwards, revealing it to be a plastic printed film above the light fixtures which the light is merely shining through.

When a fully possessed Weir grabs Miller's forehead and squeezes, blood seeps from Weir's fingers down Miller's face and scratches are seen after he lets go. But Weir's fingernails clearly never dig into his face at all, so there should be no blood or scratches.

Spoilers

The goof item below may give away important plot points.

Factual errors 

Cooper was in the orbit of Neptune when he activated his "thrust" to get him back to the Event Horizon. Discounting the near mathematical impossibility of Cooper being able to hit that small of a mark from such a great distance, Cooper upon entering the atmosphere of Neptune would start falling at the same speed as if he were on Earth. He wouldn't gently glide to the Event Horizon as the movie shows, he would crash into it at terminal velocity.
