Trivia: During the flashback sequence when Mitchell is in the hospital bed, Sam appears to have the gold oak leaves of the rank of Major while Jack clearly is a one-star Brigadier General.
Colonel Mitchell was the only one to try to remove the sword. For some reason no one else tries.
Daniel says that what was believed to be King Arthur's tomb was exhumed by the order of Henry II in 1278. However, Henry II died in 1189, 89 years earlier.
Trivia: General Landry was personally picked by Jack O'Neill to succeed him.
Trivia: Colonel Mitchell led the squadron of F-302s in defence of SG-1 against Anubis' forces during the Battle of Antarctica in "Lost City (2)"
Daniel tells Vala that the Ancient writing below the left pot says "The treasure is in this pot". However, when translated, it actually says "The treasure is not in this pot".
Daniel: (To Vala) I'm sure if there is a monster down here, it's gonna be much more scared of you than you are of it. Especially once it gets to know you.
Vala: (to Daniel) Isn't this where I beat you up?
Mitchell: (to Daniel) Or you can marry this chick.
Vala: Yeah! Let's make babies!
Mitchell: Well, Walter, doesn't look like we're getting the band back together.
Teal'c: We are attempting to build a whole new system of government that will span Jaffa worlds throughout the galaxy.
Cameron: Yeah, how's that going?
Teal'c: Not good.
Mitchell: (to Vala) Ladies first.
Vala: (to Daniel) Well then, after you.
Vala: Try playing hard to get.
Mitchell: Eh, look who's talking.
Landry: Your service record is impeccable, Mitchell. What's wrong with you?
Landry: Fact is, I like yelling at people. Never get the damn chance.
Mitchell: I'll try not to lower the average, sir.
Mitchell: You're the foremost expert on the Ancients.
Daniel: Yes – that's why I'm going to the City of the Ancients.
Mitchell: Wow. Politics really do suck wherever you go.
Mitchell: Besides, Dr. Lee is pouting because you got the job.
Mitchell: No. I made that up.
Landry: A general is only as good as the people he commands.
Jack: Who said that?
Landry: I just did. I mean, Douglas MacArthur may have said something similar . . .
Mitchell: I was hoping you could tell me something personal.
Soldier Dave: People call me Dave.
Mitchell: Yeah...it says here that that's your name...
Vala: While I would normally be thrilled to have so much testosterone at my disposal... where's my Daniel?
Vala: (to Landry) You're not going to bore me with your personal life, are you? An hour or two of that might break me . . .
Vala: I haven't been this disappointed since Daniel and I had sex.
Mitchell: (to Teal'c) Whoa! Whoa! Whoa, man! Bullets bounce!
Mitchell mentions reading the files of the case where the team first encountered the transmission stones. This was a continuous gag throughout the season about Mitchell reading all the SG-1 files is actually a reference to Ben Browder. He wanted to see all previous episodes of the show before the new season started. He watched around 180 episodes in a row.
Ben Browder was originally in the running for the role of Stargate Atlantis's John Sheppard, but had to pull out due to filming commitments for Farscape: The Peacekeeper Wars. Joe Flanigan got the part and Browder was kept in mind when the role of Cameron Mitchell was formed.
Louis Gossett Jr. was considered for the role of General Hank Landry. He ended up on the show anyway as he was cast as a Jaffa leader named Gerak.
On Sky One the opening credits were full-length and replaced the 10 second version that lasted up until "The Fourth Horseman" for the U.S. version
Syndication Premiere: September 23-24, 2006
Season 9 in Canada began airing on Thursday, November 8th, 2005 on ASN and Monday November 10th, on SPACE and Friday, November 14, 2005. Season 9 in Australia did not air until the end of June 2006.
For Season 9 and beyond, the producers originally considering renaming the show Stargate Command, but decided to stick with the original/ongoing title.
This episode marks the first mention of the Wraith on the series.
Season 9 will air in the UK Tuesdays at 8 p.m. on Sky One starting from 18th October.
The hologram of Merlin is played by Matthew Walker, who previously portrayed another Ancient named Moros in the Stargate Atlantis episode "Before I Sleep". It is possible that they were intended to be the same character. He also played King Roham in the Season Two episode "Touchstone".
The opening credits now feature a Pegasus Galaxy wormhole instead of a Milky Way Galaxy wormhole.
Teal'c is now sporting a Greco-Roman haircut.
Excerpts written by Robert C. Cooper and Brad Wright
Richard Dean Anderson is listed as Special Appearance By and Claudia Black is listed as Special Guest Star.
As of this episode, the stars' names are shown over the first scene as the episode starts, and then after the "teaser" the opening credits are shown - they're only ten seconds long and only show a few brief scenes and the "created for television" blurb.
The new title sequence for season 9 is not seen until episode 11, The Fourth Horseman Part II. However the title sequence has been included for all the preceding episodes to "Fourth Horseman (2)" including this one for the season's Australian transmission and the DVDs.
As of this episode, Richard Dean Anderson, Michael Shanks, Amanda Tapping, and Gary Jones have all appeared in ten different seasons of Stargate: all nine seasons of Stargate SG-1, and the first season of Stargate: Atlantis.
Michael Shanks (Dr. Daniel Jackson) sports a beard for the first five episodes of Season 9 to make him look less like Ben Browder.
Ben Browder (Lt. Colonel Cameron Mitchell) and Claudia Black (Vala) were previously regulars on Farscape together. They played John Crichton and Aeryn Sun respectively.
The devices Vala tricks Daniel into wearing are very similar to the I-Yensch bracelets from Farscape, which also linked the two wearers together.
Mitchell: Did I mention I'm on a mission from God?
Referencing the movie The Blues Brothers, where when trying to put their old band back together, Elwood (Dan Aykroyd) says, "You see, we're on a mission from God."
Mitchell: You ever get a bad feeling about something?
Alluding to the Star Wars movies, where "I've got a bad feeling about this" is uttered by several of the lead characters (Han Solo, Luke Skywalker, Princess Leia, young Obi Wan Kenobi, Anakin Skywalker).
Vala: (to Mitchell) I know we haven't met. That I'm sure I would have remembered.
Subtle allusion to the fact that the two actors playing these characters were together on the series Farscape.
List of Ancients
On Stargate: Atlantis, the team sent back a list of names of the Ancients who returned to Earth when the city of Atlantis was abandoned shortly before the Wraith were to overrun the city.
General Landry: I'm talking about your kryptonite.
Kryptonite is a piece of the planet Krypton, native world of Superman. He is made weak and can die from exposure to kryptonite.
Vala: ...other than it seems to have a rather interesting if somewhat limited gene pool.
This is an inside joke about and a reference to the -- according to some people -- amazing resemblance of Michael Shanks and Ben Browder. Pictures comparing the two circulated on the web when it was announced that Browder would be joining the cast on Season 9.
