Unnatural Selection (2) - S6-E12
Other mistake: When Thor reveals to SG-1 that the Replicators have reversed the time dilation device, he says time is moving at a factor of "10 squared" (100 times faster than real time). Carter says that in the hour that passed, 4 days have passed for the Replicators (which is correct), but then says depending on when they did it, hundreds of years could have passed. But that's not possible since that means years in real time would have passed. But the Asgard didn't set this trap years ago, just recently.
Birthright - S7-E10
Other mistake: One of the female Jaffa has a bare midriff showing, but there is no pouch for the symbiote.
Character mistake: Sometimes in the show, when a Goa'uld or Tok'ra is speaking (as opposed to the host speaking), they will say "my symbiote", such as when facing danger or illness: "my symbiote will protect me" or "my symbiote will heal me." However the Goa'uld and Tok'ra are the symbiote and they should be referring to themselves protecting or healing the host's body.
Emancipation - S1-E4
Character mistake: After trading the pistol for Carter, Jack says "there's only 5 more rounds in that clip." However, the pistol didn't have a clip, it had a magazine, which is completely different. As a member of the Air Force who has been trained in firearms, he would know the difference.
Summit (1) - S5-E15
Plot hole: During the briefing at the Tok'ra base about the deadly symbiotic poison, Ren'al says that dying symbiotes release their own toxin which is just as deadly to the hosts. Yet in other episodes when a symbiote dies in the host's body, the host doesn't die, even without medical treatment. For example, the whole infected town of Steveston is just fine when all the symbiotes are killed (s06e05).
Other mistake: In several episodes throughout the series, SG-1 is coming through a planet's Stargate but there's no sign of a MALP, even when it should be in the shot. SGC wouldn't send a team through without sending a MALP first (not only to check for a DHD, but survey the land, check for habitability, etc). And if the idea is "well, maybe they have a recovery unit go fetch it before SG-1 goes through", then why would the MALP be present in all the other episodes?
Brief Candle - S1-E9
Other mistake: Jack made it quite clear that he was 40 years old when talking to Kynthia, so if his birthday was in '52, that would put him at 45, instead of 40 years old.
Factual error: In several episodes, there are mentions of travelling many million light years, even though they're still in our own galaxy. However, the Milky Way is estimated to be around 100,000 light years in diameter.
Other mistake: At the end, Anubis/Vaselov is sent to KS7-535 and we see a shot of the gate being partially buried in snow and Anubis frozen. However, the wormhole should have cleared all the snow in its path when it established, meaning it wouldn't be buried in the snow as seen.
Character mistake: When Hammond and Carter come out of the base, Hammond is told he's been gone 22 hours. Hammond says he's only been gone about 20 minutes. To which Carter says, due to time dilation, time is moving an average of 600% slower and that telling O'Neill to wait 5 minutes would be 6 hours or more. However, 600% is just another way of saying "6 times" and time is slower by about 66 times, so she should have said an average of 6,000%. 5 minutes being 6 hours would be 72 times slower.
Character mistake: In the first scene in the coffee shop, Pete suggests going to the Zoo and Sam tells him there is no zoo in Colorado Springs. Colorado Springs does have a zoo, that was founded in 1926 and has operated continuously since. It is less than 3 miles from the city center and Sam both attended The Air Force Academy, and has lived in the city for at least seven years, so it is inconceivable she wouldn't know it exists. Also her answer appears genuine and not intended to deflect Pete's invitation by lying. (00:04:30)
Other mistake: Teal'c says "Mother ships do not possess cloaking capabilities" But Apophis in season 4 had cloaked Mother ships.
Continuity mistake: When Carter gets stuck in the elevator, she's on level 22. Every time the level changed, you can hear a beeping noise and there's no noise after we see 22. But from outside, the doors say 28. It wasn't a cut away shot either.
Character mistake: In newspaper article "Anubis plans to retake Dakara", there's a line that reads "being partially ascended has it's benefits." The word should be "its."
Character mistake: When Daniel Jackson learns about the fact that his wife, Sha're, has returned with a dormant Gua'uld, he does not take her to Thor's Hammer that got repaired in S2E6. Even though he was with Teal'c, that doesn't pose any issues since he is deliberately exempted from the Hammer.
Visible crew/equipment: At the very start in the briefing room, the Trinium is being passed to Sam and Jack as the camera tracks left, and we can see the reflections of standing crew (Daniel, Sam, and Jack are seated) and the moving boom mic on the glass window, towards the left. (00:00:15)
Visible crew/equipment: After Jack kills Fro'tak and disintegrates his body with the Zat gun he hides from the guards, then as soon as it cuts to Teal'c and Drey'auc at the house, four T-marks become visible on the floor - white, orange, pink, and blue. (00:23:15)
Visible crew/equipment: After Daniel finally collapses in the supply room Jack hugs and comforts him, then it cuts to Sam telling Hammond about the probe's data, and an actor's T-mark is visible on the floor near the stairs. (00:39:10)
Visible crew/equipment: When Teal'c is being led away in chains Hammond says the chains were Maybourne's idea, and as the camera is dollying out the chalk T-mark becomes visible on the floor at Jack's feet, particularly when he walks away. (00:11:00)
Visible crew/equipment: After Simian has revealed to Hammond and everyone else why Linea is known as the Destroyer of Worlds, the alarm soon blares and Hammond races to the Operations room. When he's told about the unauthorized gate activation, the white T-mark is visible on the floor. (00:41:00)
Answer: While the series was undeniably successful, filming it is a long process, taking many months of often long days. Anderson, after several years of doing this, wished to spend more time with his young daughter, who he felt he was neglecting, and requested that his role in the series be scaled back. Ultimately, he decided to leave the main cast altogether and only make occasional guest appearances.
