"Revisions" is the 5th episode from the seventh season of the science fiction television series Stargate SG-1 and is the 137th episode overall. It was first broadcast on the Sci-Fi Channel on July 11, 2003. The episode was written by Joseph Mallozzi and Paul Mullie and was directed by Martin Wood.
In the episode, Stargate Command discovers a civilization living in a seemingly perfect dome on an otherwise toxic, unliveable planet. After making contact, SG-1 learn that the inhabitants are all neurologically connected to a central computer known as The Link, from which they can access any information, at any time. Believing everything is not as it seems, Major Samantha Carter (Amanda Tapping) learns from one of the inhabitants, Pallan (Christopher Heyerdahl), about their technology, whilst Dr. Daniel Jackson (Michael Shanks) attempts to find out more about planets history and the dome's creation.
The writers pitched the episode as a standalone story, that would not rely on any of the greater mythology of the show, whilst hoping to recapture the team-driven exploration stories found in earlier seasons of Stargate SG-1.
Plot
Stargate Command makes contact with a planet with a toxic atmosphere, on which a strange dome exists. The MALP probe is able to enter the dome, where inside they see a beautiful landscape. SG-1 journey to the planet and after discovering the dome has a breathable landscape soon encounter a young boy named Nevin (Liam Ranger). Nevin takes the team to his town to meet his father, Kendrick (Peter Lacroix) who sends them to their ruling council. There, SG-1 learn that the townspeople are all connected through a neural interface to a large library of knowledge, which they can access at any time, known as the link. Interested to learn more about the inhabitants, the team stay in the town overnight, with Colonel O'Neill (Richard Dean Anderson) and Teal'c (Christopher Judge) staying with Kendrick and Nevin, who becomes enthralled in the idea of becoming an explorer. Meanwhile, Major Carter (Amanda Tapping) and Dr. Jackson (Michael Shanks) stay with Pallan (Christopher Heyerdahl), a technician who maintains the dome and his wife Evalla (Tiffany Lyndall-Knight). They discuss the premise and concept of the Link, even offering Daniel a chance at accessing the huge pool of knowledge. During the night, unbeknownst to SG-1 or the townspeople, a woman from the ruling council awakens and exits the protective dome.
In the morning, Pallan shows Sam the control room for the Link while Evalla takes Daniel to the unused library. While Sam looks at the control interfaces of the Link, the monitors suddenly flash some strange code and every person in the city suddenly stop for a few seconds, staring blankly into space as the council had, then continue on, as if nothing happened. SG-1 offers the council the option of relocation, to which they dismiss. Daniel then inquires about the woman who was on the council when they last met, to which they rebuke the idea of ever having a woman on the council. Afterwards, Sam interfaces with the Link through a laptop and suddenly becomes alarmed with several problems Pallan is unaware of. Yet, after Sam tries to convince of impending danger, Pallan will not believe his instruments lie. After agreeing to take Nevin and Kendrick to another world, Teal'c and O'Neill soon discover that the MALP is missing, with Sam determining that the dome is losing integrity and collapsing in on itself. Evalla suddenly leaves Daniel, who despite following, soon loses track of her.
After going to retrieve the hazmat suits, O'Neill and Teal'c encounter Nevin who brings them to a building, which he claims is his home. Kendrick and Nevin are entirely unaware that they have moved house and also deny having ever asked to go to another world with O'Neill and Teal'c. Daniel makes the discovery that there were once some 100,000 people living in the dome, whilst Sam determines that the power-supply is failing and the Link is killing off inhabitants and altering the memories of those left in order to preserve the rest of the population and dome as long as possible. Unable to convince Pallan, who cannot even remember his wife Evalla, Sam forcefully removes the Link device from him. As the rest of the population, now fully controlled by the link move to surround O'Neill and Teal'c, Pallan is able to reprogram the Link to erase all knowledge of SG-1, causing the inhabitants to stand down. The townspeople remove their links and over the following days are helped to relocate to another world by Stargate Command.
Production Development and casting
The episode was written by writing duo & co-executive producers Paul Mullie and Joseph Mallozzi. During the episodes development, it was originally known as "Bubble World" and was pitched as a standalone episode that did not rely on any of the ongoing story arcs or greater mythology of the show. According to Mullie, the genesis of the story had been "kicking around in different versions for a couple of years". The duos original pitch was for a far darker story, however, executive producer Robert C. Cooper steered them in a different direction. After putting the story to the rest of the writing staff, a number of changes were made; the character name Evanna was changed to Evalla, with Mallozzi commenting that "Evanna reminds Paul of Ivana Trump", whilst the young boy, who was originally called Aidan was instead changed to be Nevin and Parlan became Pallan. Writing the script, Mallozzi and Mullie constructed the dialog in their typical manner "throwing out variations on lines, different attacks on the respective scenes", with the complete process taking some 2 weeks to complete, whilst also working on other stories and their responsibilities as producers on the show. As the pair were drafting, Mallozzi commented that a detail regarding the way in which the "computer reboots the system" initially caused their entire story to unravel under scrutiny, but was fixed by giving additional detail on the parameters of the computer in the story. In an earlier draft of the story, Daniel Jackson would have tried on the link and had his memories altered; with the team having to try and get through to him in the episodes climax. Mallozzi explained that this was taken out of the story as "it seemed highly unlikely that they would risk connecting to that alien device before having it thoroughly tested first".
Director Martin Wood noted that a number of changes were made to the story due to budget constraints and Richard Dean Anderson's reduced schedule, with the original intention that the scenes involving O'Neill and Teal'c being perused around the town by the inhabitants would take place at night. Additionally, the final scene of the show would have originally involved the entire team talking to Pallan and the other townspeople, but this was reduced to just Sam and Pallan. Mallozzi later commented that it was a rare script for him, in that he knew exactly where he wanted to the end the episode, with "a final moment in which one of the characters asks Carter to tell him about the wife he no longer remember". Discussing the original, darker concept for the episode, Mallozzi expressed his reluctance to reveal the "shocking conclusion" that he originally envisioned, "because the story we ended up with was so different that I'd love to repurpose it given some future opportunity", later stating that he might adapt the original pitch into an episode of his series Dark Matter.
"Revisions" marks the first appearance of Christopher Heyerdahl in the franchise, playing Pallan in this episode. After being cast in the episode, Heyerdahl and director Martin Wood realised they were neighbours and went on to become friends. The following year, Heyerdahl was cast as Halling, a reoccurring character on spinoff Stargate Atlantis and would later play another reoccurring character nicknamed "Todd". Heyerdahl, along with Amanda Tapping also went on to star in Sanctuary together, with Wood producing. Peter LaCroix was cast as Kendrick, with director Martin Wood commenting that he felt enough time had passed since LaCroix previously played the Goa'uld Ashrak in the season 2 episode "In the Line of Duty". Liam Ranger portrays the character of Nevin, whilst Tiffany Knight plays Evalla, having previously portrayed a Jaffa in "Within the Serpent's Grasp" and La Moor in "Touchstone". Gary Jones reprises his role of Walter Harriman. Episode director Martin Wood cameos as a Stargate Command technician, as does writer-director Peter DeLuise. Shank's stand-in Finn Michael portrays both Daniel Jackson and a councilman.
Design
Location manager Lynn Smith began scouting for locations whilst Mullie and Mollozzi were still writing their script. Mullie commented that they wanted the location to convey an aura that the world was "too good to be true", with Mullie elaborating "we wanted to create a kind of mini-perfect, almost Disneyland-esque little village". The team discovered and secured use of an amusement park, Fantasy Gardens in Richmond, British Columbia for the episode. Mallozzi commented that the location worked perfectly as it "looks like a place that has no reason to exist, but it actually does", going on to note that "it looks so fake. But we wanted it to look fake". When dressing the set, the production team were careful to make sure that there were no photographs or portraits used for decoration in order to further the idea that the inhabitants would have no idea that people were disappearing from the dome. Costume designer Christina McQuarrie dressed the inhabitants of the alien world with very little colour in any of the outfits, as well as making the garments very form-fitting and smart. Wood wanted this to contrast the colourful world and also give the impression that they weren't technologically advanced, as well as making them look creepy and unusual. A big discussion point during production meetings was whether or not to show the Link that was controlling the inhabitants, ultimately opting for a small removable implant that would sit on the side of the subjects face.
The computer core was created back on a soundstage. Director Martin Wood gave production designer Bridget McGuire the brief of creating a space with lots of plexiglass and "things we don't see" in the alien village itself. McGuire continued the red brick aesthetic found at Fantasy Gardens at the entrance of the room, then looked to create a space that contrasted "the quaintness of the village", opting for a "very futuristic, shiny and quite stark" look. Art director Peter Bodnarus explained that they reworked "honey-coomb looking creates and turning them into our idea of a self-replicating building block-type of alien world" for the walls of the structure. New addition to the production design team, Rodrigo Segovia commented that creating the centre console for the room was his "trial by fire" and that they wanted to create a piece that was "a standalone piece, yet had to fully integrate with the rest of the set elements".
