Errores

(at around 26 mins) Right before the team goes into the Stargate for the first time, Catherine gives her necklace to Daniel. Shortly after, there is a shot of Catherine watching them go, and you can clearly see the necklace still around her neck.

(at around 29 mins) When Daniel Jackson reaches the other end of the Stargate for the first time his face is all sweaty. In the next shot his face is completely dry.

When Daniel and his team first enter the city, his pendant is tucked under his shirt, but in the next shot out of his shirt, then in the next shot, tucked back into his shirt.

(at around 1h 35 mins) The pace at which the bomb's timer ticks down changes several times.

(at around 14 mins) The symbol for Orion that doctor Jackson identifies using the newspaper changes. In the earlier shots of the cover-stone, the lowest symbol lacks the arm and bow that we normally associate with Orion, and does not look like the symbol Jackson draws but when he goes over to the cover stone to compare the symbols (the arm and bow make a sudden, momentary, reappearance, just for that shot). Also, the computer image of the sixth symbol, which you see when they're activating the gate the first time, also lacks the arm and bow.

The crew is using a satellite receiver when on the other world. A receiver needs a satellite in orbit to relay a signal. They could not have sent up a satellite. And they could not have been communicating with Earth.

(at around 23 mins) When Stargate was initially tested with a probe, they had a system that indicated the probe's molecular deconstruction and a star map to show its location, which turned out to be "on the other side of the known Universe". Although by that point in the movie they had some general idea about Stargate's operation, it wouldn't be enough to construct devices capable of such functions, which go far beyond our present knowledge (the movie clearly implies that the events happen in the 20th century). In particular, a star map indicating the position "on the other side of the known Universe" simply cannot exist, if only because all existing star maps encompass only a small portion of our Galaxy, which is just a tiny speck compared to the size of the observable Universe. Somehow they managed to squeeze every star in the Universe into a glass board some 15 feet in length.

(at around 42 mins) When the Earth team reaches the mining camp and scans the mineral, the readout comes back, "Quartz: primary element." Quartz is not an element, but a mineral compound, something a sophisticated mineral analyzer would probably be able to deduce.

(at around 43 mins) The candy bar that Daniel gives to the village leader isn't melted but still crunchy even after hours spent in the desert in his shirt pocket and being dragged through the sand by the yak-like creature. Even though there are "military grade chocolate" bars, known as "The Desert Bar", created to withstand heat of up to 140 degrees Fahrenheit, Daniel's bar was clearly not that variety but was a common 5th Avenue chocolate bar.

(at around 1h 35 mins) Nuclear weapons come fully assembled (for both safety and security reasons not the least of which is to contain radioactivity). An arming device is required to enable the weapon. There should be no reason for Colonel O'Neal to do much more than insert the arming device and activate the timer on the weapon.

(at around 13 mins) During Dr. Daniel Jackson's first discussion of the age of the cover stones, Dr. Barbara Shore mentions carbon dating. Carbon dating technique would be useless on stone or metal; it can give the age only of once-living matter. However, the carbon dating might have been used on discovered organic residue that the cover stones were placed on top of or that has some other connection to them.

Despite the amount of machinery used to activate the gate on Earth, none was needed on Abydos. The Stargate's ring spins like a combination lock. Once the correct symbol is aligned, the mechanism locks it in and the ring is twisted to the next one. All the machinery in the silo was to ensure that no one had to turn the ring by hand.

(at around 24 mins) The premise is that the glyphs represent star constellations which are used as a kind of coordinate system. If that were so, then the problem on the other side would not be to find some tablets to help decipher the symbols. The actual problem would have been that the star constellations look completely different when seen from a different planet thousands of light-years away. In fact, with changes of magnitude, some stars might not be visible at all, while other stars form completely different constellations when watching the night sky from the remote planet. So you would have to observe the night sky until you found all the constellations used on the remote gate, but even if you identified them, you would have no clue where Earth was in that second coordinate system.

However the Ancients seem to have already taken this into account, with the stargate addresses being specific to each stargate (As Daniel points out when they see video of the other stargate from the probe footage "These markings are different. They don't match the symbols on our gate."). Therefore, all they would need is the cartouche on the Abados cover stones in order to have the location of Earth ... which they had, but what they didn't have was the symbol for the point of origin, Abados (the pyramid with 3 moons).

With a one-to-one relationship, stargate addressing wasn't an issue with this movie, however it became an issue when they made the movie into a TV series (Stargate SG-1 (1997)), with Abados having multiple addresses it could dial to.

(at around 44 mins) At one point, one of the characters comments that the Stargate is made of the same "mineral" that the natives are mining. This cannot be technically correct, as a mineral is a naturally occurring substance, whereas the Gate must be made from the metal that is refined from the mineral (i.e., 'ore').

However, a "gold mine" is never referred to as a "gold ore mine" so the statement could be considered correct.

No one has tried to travel back through the Stargate before so the soldiers have no way of knowing that is not possible. Plus the probe was able to send telemetry back to Earth, suggesting two-way travel is possible. It was a major plot element, not a plot hole, that travelling back needed new co-ordinates. It was never suggested that return travel was not possible. Moreover, radio-communication is different from transporting matter.

(at around 31 mins) When the team first exits the pyramid, Jackson presses his hands against the "solid" stone wall as if testing it for stability. The wall can be seen moving when Jackson presses it.

(at around 20 mins) During the dial-up, as the chevrons are locking, the symbols on the computer screens do not match up with what is on the Stargate.

(at around 31 mins) The three "moons of Abydos" seen above the pyramid are obviously images of Earth's moon, merely re-sized and rotated relative to each other.

(at around 39 mins) When O'Neil and the team first discover the mining operation, the long lines of natives that are supposed to be walking back and forth between the mines and the central tent do not move at all but are in fact static images.

(at around 1h 40 mins) You can see O'Neil's shirt is already cut before the "kid" scratches him on the back in the last fight scene.

(at around 50 mins) When miners have celebration feast or "welcome party", one group of them is sitting around fireplace. It's clear that fire is coming from a gas ring burner, not wood.

(at around 3 mins) In the opening scene, depicting a car from the 1920s, the sound effect of the horn is obviously of a dual-note horn from a modern car.

(at around 1h 19 mins) It is clear that the cat's mouth does not move the last time the cat meows onscreen.

(at around 38 mins) After Jackson is awakened by the desert beast, O'Neil looks out into the desert. You can clearly see the crew and a very large bounce card in the right lens.

The camera crew is clearly visible reflected in the dark sunglasses O'Neil and the rest of the team wear in the beginning of the movie. This is most noticeable in the Blu-ray release of the movie due to the higher resolution video.

(at around 1h 16 mins) In the first attack on the village, after the leader is knocked down by an explosion, a ship swoops down from the sky and the model's cables and guide wires can be seen.

(at around 44 mins) When O'Neil orders the soldier to "radio" base camp and keep it secure until they return, just before they are initially escorted by the miners to the village, two circular stage lights can be seen reflected in O'Neils' sunglasses whenever Kurt Russell's head is facing forward.

When the Stargate is first revealed to Daniel Jackson, you can see blueish lights on the ceiling of the gate room. These are so-called PAR fixtures, usually used for Rock'n'roll concerts and in discotheques. They are obviously part of the film crew's lighting rig and not any kind of lamp the military would use.

(at around 21 mins) There are 39 glyphs (symbols) on the stargate. After Daniel "discovers" the 7th symbol in the dialing sequence, and they dial the first six, the technician comments that six symbols was as far as they'd ever gotten in the (minimum) three years they'd been working on the device. With only 39 possible options for the 7th symbol, using simple trial and error, they would've discovered the 7th within 39 attempts (33 assuming no repeats in the sequence). At just one attempt per day, and they would've figured it out in a month. The same thing applies to the gate on Abydos - they knew the first six. Even though the 7th was worn off, there were only 39 possibilities.

(at around 33 mins) When the team make their first trip through the gate, the soldiers expect Daniel to work out how to get them back. When he cannot do this, he is vilified. However, for safety, the now Stargate Command could have allowed a set time to elapse, then dialed the same address to check on the team.

The true purpose of the mission (the destruction of the Stargate on Abydos if enemies were found) was not explained in any sensible manner. If O'Neil was expected to detonate the nuclear weapon, what was supposed to occur if he was injured or killed and could not complete the task? Additionally, the assembled group was not warned of the possible risks of mission failure which violates basic military protocols. Assuming that some of the men had families, sending them on what was possibly a suicide mission without informing them of that fact and asking for volunteers risked the mission becoming a failure if the men discovered the true reasons and then disobeyed orders or mutinied.

Ra plans to send back the bomb with its power boosted 100 times, and expects this to end civilization on Earth. It's not said what the normal yield of the bomb is, but there is no reason for it to be enormous. A two megaton bomb boosted to two hundred would be no bigger than the biggest bombs already tested. The highest yield nuclear weapon tested was 50Mt "Tsar."

It would also explode underground and probably do little damage. But there is nothing to indicate that Ra knows where the Earth-based Stargate is, so that much is reasonable. Ra obviously added power to the bomb in order to overload the Stargate on Earth causing an explosion bigger than the bomb. Although these points were only given in SG1, the audience would have no idea about what the gate was made of or how it would react to a nuclear blast.

You may need seven coordinates to characterize an abstract 'course' to a position in three-dimensional space as described, but in practice, the starting position for a jump through the stargate must always be the stargate itself, at its current position, wherever that may be. Therefore, there would not be a need to dial a seventh glyph. But that would have meant there was no need to bring in the main character Daniel Jackson, they could have just dialed combinations at random without even understanding what the glyphs meant or how many were needed to reach another stargate.

This may be a security feature. The average slave would not understand the symbols, and would have to know that symbol to activate the gate.

(at around 49 mins) The gold jewelry given to Daniel Jackson was referred to as the "Eye of Ra." However, the engraving on the medallion is the "Eye of Horus". Both are almost identical, but Eye of Ra "looks" to the right, instead to the left as depicted in the movie.

Throughout the movie, Kawalsky's character wears the rank of Lieutenant Colonel (he is second in command under O'Neil), but is referred to as "Lieutenant". A Lieutenant wears either a gold or silver bar, not a silver oak leaf, and a Lt. Colonel is never referred to as "Lieutenant".

All the other "Lieutenants" are wearing NCO stripes as well.

(at around 11 mins) Dr. Jackson at one point refers to the writing as "hieroglyphics," which no self-respecting Egyptologist would ever do. "Hieroglyphic" is an adjective. An Egyptologist would call the writing either "hieroglyphs" or "hieroglyphic writing."

(at around 27 mins) When walking up the ramp to the stargate on earth, Col. O'Neil holds his gun with his index finger on the trigger. No trained soldier would do that unless he intends to fire the gun. Soldiers (and other people handling guns) are trained not to put their finger on the trigger unnecessarily for safety.

In the discovery scene in the 1920s, there is no obvious reason why the excavators would stand the Stargate up on its edge, and many reasons not to attempt it. Similarly, in the 1980s scenes in the underground facility there is no reason to stand either the capstone on its edge, risking damage to the unsupported stonework, or the Stargate.
