Jack says to Daniel, "... And who translates when you go Ancient?" Both Jack and Teal'c should know how to translate Ancient because they had to learn how to read it and understand it in "Window of Opportunity" to stop the day from happening again.
When Daniel attempts to look into the ancient device and Jack pulls him away, Daniel's back is towards the pillar. However, when the camera angle changes, the pillar is to Daniel's right, and he points to the device, which is supposedly behind Jack, but should be to Daniel's left.
If Daniel doesn't like beer as mentioned in a few previous episodes, then why does he keep drinking it?
In this episode Daniel says that at the start while trying to get the Stargate to work he used to stand and look out the briefing room window at the Stargate for inspiration. However, in the movie Daniel is not introduced to the Stargate until he has finished translating the cartouche.
The block of C-4 that O'Neill slaps on the corner of the wall by the Ancients' knowledge device, magically moves 20cm to the left as he turns to watch the descending death gliders.
Documents labeled "eyes only" are NOT to be removed from wherever they are stored.
Hammond: I've read Dr. Jackson's report on his translation. Given what happened the last time you encountered something like this, I'm surprised you're so willing to take on this mission.
Jack: So am I, sir.
Daniel: Why wouldn't we wanna gain access to the greatest repository of knowledge in the known universe, once and for all find the lost city of the Ancients, and use their advanced technology to save the entire galaxy from the evil oppression of the Goa'uld?
Jack: Well, there's that.
Jack: Thank God, pizza. (opens the door and sees Hammond) Well, you're not the usual delivery boy.
Sam: And then, it will overwhelm his nervous system, and the Colonel will...
Jack: What? Meet my maker? Pay the piper? Breach the pearly gates? Start pushing up daisies here and there?
Jack: ...you're so wrong. It's a perfect analogy, Burns as Goa'uld.
Teal'C: They are merely animated characters, O'Neill.
Bra'tac: Has Hammond of Texas fallen in battle?
Jack: And you are . . .?
Weir: Dr. Elizabeth Weir.
Kinsey: You can just call her your one hope of ever stepping through the Stargate again.
Jack: Bit of a mouthful...
Hayes: It was 'Lieutenant' last time we spoke.
Hammond: For both of us. That was a lot of hair ago.
Jack: I hope you like Guinness, sir. I find it a refreshing substitute for . . . food.
Jack: Is that doughnuts?
Jack: Excellent . . .
Jack: Carter, you're one of this country's natural resources, if not national treasures.
Jack: We could have Goa'uld on our collective asses any minute now...
Sam: The fate of the world is hanging in the balance and you've been sitting in your truck working on this (crossword puzzle)?
Jack: I believe it was double or nothing.
Jack: I need a seven letter word.
Daniel: I told Sam I wouldn't help you.
Jack: Then this will be the one thing she doesn't know. Up, Down, Charmed . . .
Jack: Yeah. Well, thanks anyway.
Daniel: The word you're looking for . . . (Jack cuts him off)
Jack: You're so shallow.
Daniel: (babbling drunkenly) Oh please. Teal'c is like one of the deepest people I know. He's so deep. Tell him how deep you are. You'll be lucky if you understand this.
Teal'c: My depth is immaterial to this conversation.
Daniel: Oh! You see?
Jack: (to Daniel) No more beer for you.
Jack: Three days from now is a Thursday. Thursday's not good for us.
Sam: Twenty-three across, the atomic weight of Boron. The answer is "ten."
Sam: You wrote the word "fat."
Jack: Your point?
Director Martin Wood's cameo: the airmen correcting O'Neill's crossword in the elevator.
In the crossword puzzle Jack is working on, Up, Down, Charmed, Strange are all flavors of Quarks.
When originally televised, "Lost City, pt.1" and "Lost City, pt.2" were aired as separate episodes, the second part airing the week after the first. Each episode had its own opening and closing credits, guest stars listed, writers and title. When placed on the DVD, these episodes were edited into one episode approximately an hour and a half in length, under the sole title "Lost City".
This episode (both parts) is the only time that Jessica Steen appears as Dr. Elizabeth Weir. Actress Torri Higginson plays the role in the eighth season opener, "New Order," and in 'Stargate: Atlantis.'
Ron Blecker, one of the SG-3 airmen, is the show's military consultant/advisor - this is his first credited appearance in front of the camera.
The President's visitor, Bonnie, is Bonnie Arbuthnot, a development director in Chicago who won the SciFi Channel's "Get in the 'Gate'" contest for a walk-on role as a White House staffer.
Jack says his favorite show is on in half an hour. The next day he says that the invasion in 3 days is a Thursday. Therefore, Jack's favorite show airs on Sunday. That plus many other references, let us determine that Jack's favorite show is in fact The Simpsons. Anderson's favorite show is The Simpsons as well (http://www.sci-fi-online.50megs.com/Interview/RD_Anderson.htm).
The script for this episode (both parts) are based on the script for the film Stargate 2.
In the opening scene it appears as though the word Jack has written in the crossword for 1 Down is "FCUKTEO". (Take that whatever way you want) The rest of the crossword is riddled with misspellings, like "TULIPP*". (5th row, across, last letter blank) Furthermore Sam's comment in a later scene is accurate; Jack did indeed write "FAT" as the answer to 23 across, "the atomic weight of Boron."
Jack: And a few days after that, it's goodnight, my someone, goodnight.
"Goodnight My Someone" is a song performed in The Music Man, a musical play which opened on Broadway at the Majestic Theatre on December 19, 1957. The film version of the play was released in 1962.
Jack: Does anybody know anybody who voted for those shrubs?
Jack is referring to fictional President Henry Hayes and Vice President Robert Kinsey, using a term which has been applied to George W. Bush by his detractors and political opponents since his days as governor of Texas (1995 - 2000).
Jack was clearly trying to say it the same way Mr. Burns from The Simpsons says it.
President Hayes: Kinsey delivering Florida
President Hayes mentions that Kinsey delivered Florida in the presidential election. This appears to be a reference and/or in-joke to the controversial 2000 U.S. elections where Bush won after a heavily contested series of recounts in Florida.
Col. Jack O'Neill: It's the perfect analogy: Burns as Goa'uld.
Another reference by O'Neill to his favorite TV Show: The Simpsons. What better counterpart to Goa'uld in Springfield than our beloved 'evil' Mr. Burns?
