  • Replicators create doubles of Sheppard, McKay, Ronon, Teyla and Weir.

    Bring back Elizabeth Weir! Permanently! Samantha Carter was great on SG1 but she doesn't belong in Atlantis. No one cared about Atlantis and the ancients like Weir. I loved them all being united again, it made the episode fun to watch. The characters and actors have such good chemistry. Carter seems out of place with them. It was a funny and well written episode but it seemed they were letting us know that Weir was definitly not coming back. I'll admit, I didn't think her character was that important until she left. If anyone should have replaced her from SG1, it should have been Jackson, at least he was interested in, and knew a lot about Atlantis and the Ancients.moreless

    The Mortal Coil was a Great Episode!!! It had lots of action, with old foes in new ways. There was plenty of drama, and mystery as well. The scenery of the episode was good as well. The planet where Atlantis now resides is beautiful at night with its multiiple moons. It also has a darker tone to it, and I wonder if this has anything to do with the future of Atlantis? This episode reminds me of SG1 when they are duplicated, and machines, but essentially the same soul on the inside. Though it is more or less the same, this episode was exciting to watch, and I can't wait to find out what happens next!!!moreless
  • ok episode...

    It's annoying seeing how much Atlantis takes from SG-1. I want something original! Anyways, the team finds a probe and eventually figure out that they're all replicators made with the memories of their real selves. In the end, they escape and meet with their real selves. I didn't really like the story, but it was funny the way the douples interacted together. I don't really care about seeing Weir again so... I think the story was drawn out and boring. The only reason the episode was any good was because of the humor and the set up for the second part. Overall, just an ok episode.moreless
  • Old team back together...

    The first part of the episode look really boring and not promising, some probe crashing into the city and Zelenka and McKay yelling each other.. and then people start acting weird - again.. that have happened before and again, the team is only one looking normal and we hear some familiar voice in the dark - until we learn that it is just another "fake" Atlantis and they are made by replicators and Elizabeth is there. So, all together, looking like on old days, trying to get away from falling city - too cliche.

    But it gets better. They got something important with them and call real their to have a meeting - McKay's together were great. But again, nothing lasts forever and... SO, maybe too cliche and already done storyline but there was something.. and it was so great to see Elizabeth again.moreless
  • Back On Form

    Having only recently got into SGA, watching all 4 seasons - to this episode, over the last 2 months, I have noticed a massive drop in plot quality. I was pleasantly surprised with sga and after committing to this show, I couldn't believe how good it was. Season 1&2 where awesome, great story-lines continuing throughout the series made this show a winner, but once the wraith battle kinda fizzled out season 3 slowed down a touch, and then they chopped the Doc & wier - I was gutted.

    Season 4 has been disappointing, filler episode after filler episode - until now!! This episode, and mainly the next, sees SGA back on track, great tactical plotting & integration of characters past. A Sexed-up episode courtesy of Mckay's cute replicator & Shepherd eyeing up Larrins "assets", its nice to see SGA up the ante for the mid season stakes. This is why I watch it!moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (7)

    • The vision that Sam Carter had in "The Seer" of Atlantis being destroyed is fulfilled in this episode. However, it's the fake "Atlantis", not the real one.

    • Goof: Near the end, Sheppard tells the control room to shut down the stargate after he walked through. You can't shut down the gate on the receiving end; it has to be shut down from the side that activated the gate.

    • The duplicate Sheppard says they can try to contact Atlantis by going to New Athos but they actually make contact with Major Jordon on an outpost on the planet M34-227.

    • Sheppard: It's not like this hasn't happened before. The other Elizabeth got infected by those little nanite things and we figured out how to stop 'em, somehow...

      At the extreme end of the Season 3 episode "Progeny", Dr. Elizabeth Weir was infected by nanites when attacked by the Replicator Niam. In the following episode, "The Real World", Weir fights off the infection while the nanites manipulate her consciousness.

    • Sheppard: Great. The last time I came face-to-face with myself I ended up kicking my own ass.

      This is a reference to the Stargate Atlantis season four episode "Doppelganger" in which Colonel Sheppard has to fight an alien entity assuming his form.

    • The Milky Way Replicators and the Pegasus Galaxy Replicators (Asurans) are different in that the Asurans were unable to take the form of living people until McKay changed their base code in the Season 3 episode "Progeny." A Milky Way Replicator, however, took the form of a living human, Samantha Carter, (Stargate SG-1 Season 8's "New Order Part 2)" before the events of "Progeny."

    • This is the first appearance of Elizabeth Weir (Tori Higginson) since she was captured by the Replicators in the episode "Lifeline" earlier this season.

  • QUOTES (8)

    • McKay: Huh...If this works, we should be able to track every Aurora Class Replicator ship in the galaxy in real time.
      (screen shows half a dozen ships)
      McKay: (relieved) That's not so bad. I guess the Wraith have really taken a toll.
      (more ships appear on the screen)
      McKay: On.. the other hand they might have built even more
      (a lot more ships appear)
      McKay: ... a lot more ...
      (sounds of more ships appearing)
      McKay: Oh, crap!

    • Sheppard: You doing OK?
      Weir: Sure, all things considered. Not bad for a dead woman.

    • Sheppard: All right do we know what the problem is?
      McKay: Yeah, the gate's not working.
      Sheppard: I think we figured that much last week when you broke it.
      McKay: I did not break the gate.
      Sheppard: It just happened to stop working about the same time you were screwing around with it.
      McKay: I wasn't screwing around with it. I was running a stream lining program to boost its operating efficiency.
      Sheppard: Yeah, well good job.
      McKay: It had nothing to do with why the gate malfunctioned.

    • (Upon seeing a duplicate of himself)
      Sheppard: Great, the last time I came face-to-face with myself I ended up kicking my own ass.

    • Replicator Keller: There's no point in calling you anything else. You're exactly like her in every way.
      Duplicate Weir: Except that I'm not her.
      Replicator Keller: No. The real Elizabeth Weir was killed several months ago.

    • McKay: (Walks in room) Hey, what are you all doing here? What's going on?
      Sheppard: (Pulls out a knife)
      McKay: Er, I'll be right back; I just remembered that I forgot to unplug something; I'll just go plug it in.
      Ronan: (Grabs McKay)
      McKay: Woh, woh, woh! Wait a min..what are you doing?. Wait!
      Sheppard: This may hurt a little. (Cuts McKay's hand)
      McKay: What is the matter with you?
      Sheppard: Here. (Passes cloth to McKay)
      McKay: I'm gonna need more than that! I, I'm gonna need some disinfectant, some stitches and...
      Sheppard: Shut up and hold on a second!

    • Duplicate McKay: (About real McKay) Oh this is great. Finally someone who I can have 100% confidence in; I cannot tell you how much I am looking forward to working with you! And this is just the beginning but humanity is about to benefit from one of the greatest living scientific minds...x2!
      McKay: Can you imagine?
      Duplicate Sheppard: I'm trying not to.
      (Sheppard smiles)

    • Sheppard: Any injuries?
      Marine: No sir
      McKay: Oh thank god it hit the reading library or someone could have really got hurt.

  • NOTES (6)

    • The outdoor scenes in the forest were filmed near Fort Langley, British Columbia.

    • The line from McKay about the old uniforms bunching up under the arms was added as an in-joke. David Hewlett and some other cast members voiced issues with the old uniforms which is why the new ones were introduced.

    • Sean Millington (Marine) previously played Ronac (Teal'c's Father) in the Stargate SG-1 episode "Crossroads" and a Thug in the episode "Affinity."

    • To distinguish between the real team and the duplicates, the real team wears the updated Atlantis uniforms and the duplicates wear the old style.

    • Amanda Tapping does not appear in this episode.

    • Terminator 2: Judgement Day:

      When Sheppard shoots Lorne in the leg, it heals in much the same as the T-1000 in Terminator 2: Judgement Day. Also the T-1000 is played by Robert Patrick portrayed Colonel Marshall Sumner in the first 2 episodes of Stargate Atlantis.

    • Title:

      This title and the conclusion episode's title are from Hamlet's famous "To be or not to be" soliloquy from Shakespeare's Hamlet, Act 3 Scene 1. "This Mortal Coil" refers to the physical body, to be shed at death.
