Continuity: When Teal'c walks into the Goa'uld force shield on the planet, he is forced off and he almost does a backflip. You can see that he would have hit the floor head/neck first. But when the shot changes, you see him land on the floor sliding on his back, as though someone had just pushing him over.

Revealing: When Jack and Teal'c are first shown in the fighter when it first enters space, if you pay attention to the stars in the background, they tend to move in a rather jerking fashion.

Revealing: When Teal'c and O'Neill are passing by Juipter (after the failed missile burn), you can see a reflection in the background window of the cockpit. But the reflection is not the backside of their helmets, but instead is the front sides matted on to give the minor illusion of a reflection.

Continuity: In the scene where SG-1 tries to get their note through the gate, watch Daniel. The camera cuts to him just before Jack slides down the zip line, and you can see small dots on Daniel's face - presumably the marks left when shot by the security system. However, Daniel has been taking cover since the alarms sounded and only gets hit when he tries to get to the gate after Jack is brought down. The next time Daniel appears on camera, his face is clear again and stays that way till the point in the scene where he, too, is killed by the security system.

Continuity: Carter and Cadet Haley enter the Stargate and we see them through the "puddle." When they come out on the other side, their positions are reversed.

Other: Osiris is a male Goa'uld in a female host (Dr. Sarah Gardner). So why does this MALE dress his host in tight, midriff-bearing, butt-accentuating outfits? It isn't to manipulate other Goa'uld, because sexual reproduction between hosts is forbidden as the child would be Harsesis and most Goa'uld find the thought of sex repugnant. While Goa'uld are physically genderless, they do, without exception, refer to themselves as male and female. Egeria and Hathor, both queens, are referred to as female. Apophis refers to Klorel/Skaara as his "son", not his offspring. If they had no gender, they would never call other Goa'uld "mates" or "children". Further, other females never dress this way unless trying to sway someone to their cause (such as Nirrti trying to seduce Jonas Quinn) and Osiris dressed like this well before she ran into Daniel again. There is no logical or plot motivated reason to dress Anna-Louise Plowman in these costumes other than eye candy for the audience!

Revealing: Even after Teal'c is dead, you can see in one shot that he is still breathing.

Factual error: When listing off the items Orlin has ordered online to produce his own stargate, Simmons lists "seven 100,000 watt industrial strength capacitors". Capacitors are measured in farads, not watts. Not to mention that as of now, the world's best capacitors are less than 10,000 farads, not an order of magnitude higher.

Plot hole: Carter says that the chance of depositing the heavy element inside the Katow sun while the element is en route is about 1%. However, hypothetically speaking, the actual chances would be infinitely smaller, in fact it would be near impossible. Simply consider the distance from earth stargate to the Katow stargate, the diameter of an average sun, and the time it takes for an object to travel through the gate (about 12 seconds). Taking the closest star to us (Alpha Centruri), at a distance of 4 light years, this means that the wormhole takes ~443ns (0.000000443s) to pass through the sun (using our sun diameter). Similarly, taking the diameter of the Milky Way as the distance to the furthest star in our galaxy, ~100000 light years, meaning the wormhole takes ~17ps (0.000000000017s) to pass through the sun. This means that the SGC would have to shut down the gate within a a maxmium of 443ns or a minimum of 17ps time gap. As we have previously seen, the stargate takes far longer to shutdown than these miniscule time lengths.

Revealing: When Jack is asking the bald guy where he got the idea for the show, you can see the camera light reflected in the guy's glasses.

Continuity: When Jack is revived in the sarcophagus after being caught, the first shot of this his shirt is in perfect condition, but in the next shot of it, there is a knife hole in the shirt which disappears when he is being taken to the "anti-grav torture wall"

Revealing: When the hallucinated Jonas is leading Dr. Kieran upstairs, a red light can be seen glowing on his hip where his Beretta is holstered. It looks as if Corin Nemec is carrying an Intar (a training weapon with a glowing red crystal in the grip) prop instead of a normal pistol.

Continuity: When Samantha Carter is locked in the storage room on deck 7 and she uses the plasma cutter to make a hole in the door, there is a fingerprint on her visor which appears/disappears between shots.

Visible crew/equipment: When O'Neill, Carter and Quinn meet Teal'c at the ship wreckage, the camera moves to focus on O'Neill. The shadow of a boom mic on the ground follows his path.

Visible crew/equipment: When Daniel is talking to Teal'c and the other Jaffa, at one point we can see a light reflecting screen reflected in Daniel's glasses, we can even see the silhouette of someone's arm and body in front of the screen.
