  • Trivia

    • In the shot in which McCoy hypos the guard distracted by Scott's saluting, the stagehand operating the door can be seen quickly darting out of the way as McCoy pushes the guard through the open doorway.

    • Trivia: This is the only original series episode where Scotty addresses Kirk as "Jim".

    • It's stated repeatedly that the transporter power is balanced for four, not that they can take a maximum of 4. But then when they lose power, Kirk has to stay behind to operate the controls. If the power is balanced for exactly four, then their plan won't work because only three will be going. They would have to take Moreau for their plan to succeed, but no one notices this or says anything.

    • In the 2006 remastered version, Kirk is in his quarters talking to McCoy and Scotty. But the scene begins with a brief scene of the Enterprise flying through space while Kirk voiceovers. However, the Enterprise is in orbit and shouldn't be flying anywhere (This was corrected in later airings and only appeared in the first weekend airings).

    • Trivia: The Enterprise in the alternate universe is called the I.S.S. Enterprise instead of U.S.S. Enterprise.

    • When Kirk and the evil Spock fight, Kirk swings his elbow at Spock's jaw and you can clearly see he misses...but Spock reacts anyway.

    • On the Enterprise bridge, Chekov is wearing a gold sash on his waist and a dagger on his right hip. He leaves the bridge and goes into the elevator. A moment later Kirk joins him but Chekov's gold sash and dagger are now missing. Instead, he has the agonizer device on his waist. When the elevator doors open, his gold sash and dagger reappear.

    • After evil Spock and Sulu chat, the camera cuts to Kirk and Moreau in Moreau's quarters and there's the familiar cabin door opening/closing "Whoosh" noise. But they're both sitting on the bed, so who came through the door? (This might result from syndication cuts to put in more commercials, but it still doesn't make much sense since no one walked through a door in the Spock/Sulu scene either.)

    • In the overhead shots, the stunt men playing McCoy and Scotty in the sickbay fight don't look much like Kelley and Doohan either.

    • Exactly how did Scotty know about the alternate Sulu's security board? He was never even on the bridge of the I.S.S. Enterprise and certainly wouldn't have known that the helm and security stations are at the same location.

    • When Kirk and company beam onboard the I.S.S. Enterprise, the ship is orbiting in a clockwise direction in the savage universe, contrary to the U.S.S. Enterprise, which was orbiting the Halkan homeworld in a counterclockwise direction in their universe. Yet, throughout the rest of the episode, the I.S.S. ship is orbiting the Halkan homeworld counterclockwise. (This is corrected in the remastered edition.)

    • When the evil Kirk yells at Spock from the edge of the brig doorway, you can see his chest extend outside the light beams that show where the force field is.

    • Is it really very likely that Spock is going to die because someone hits him over a head with a vase? Even allowing that's such a thing has never killed anyone in decades of TV "knocking someone out" sequences, this is Spock we're talking about, with greater than average pain resistance, strength and endurance.

    • The evil Spock describes his McCoy, the evil one, as "sentimental, soft." Given he permits his subordinates to wager on how much suffering a man can endure, this seems a little unlikely, or exaggerated at best.

    • Kirk gives the computer about four commands and in seconds it whips up a way to beam people back and forth between parallel universes. If it's that good, why do they keep around Spock?

    • At the beginning Kirk calls for beam-up and drops his arm. But when he beams up and appears on "his" Enterprise before switching, his arm is still upraised with the communicator in it.

    • Why does the evil Spock cut power to the transporter room? a) If he read McCoy's mind he probably knows Kirk isn't going to leave him, and b) he says he's going to let them go anyway. So he cut off the power to stop them from going, just to stroll in and tell them he's going to let them go?

    • Kirk punches the Imperial crewman that helps him in the face, but when the guy falls on the ground he's holding his side.

    • Kirk asks the evil-Spock about the Halkan's prediction of galactic revolt. When did he hear that? The Halkans in his dimension never said any such thing (why would they?), and other than a brief chat that we saw where it was never mentioned, Kirk never talked to the Halkans in the mirror universe.

    • In the sickbay fight, evil Spock's hair noticeably changes (gaining curls!) when they switch to shots of Leonard Nimoy's stunt double.

  • Quotes

    • Mirror Spock: (to Kirk) I have received a private communication from Starfleet Command. I am committing a breach of regulations by informing you of its contents.
      Kirk: Yes, Mr. Spock.
      Mirror Spock: I am instructed to wait until planet dawn over principal target to permit you to carry out our mission.
      Kirk: And if I refuse?
      Mirror Spock: In that event, I am ordered to kill you, and to proceed against the Halkans as the new captain of the Enterprise.

    • Kirk: You would find me a formidable opponent.
      Mirror Spock: I am aware of that, Captain. I trust that you are aware of the reverse.

    • Mirror Spock: Terror must be maintained or the Empire is doomed. It is the logic of history.

    • Mirror Sulu: (flirtatiously) Still no interest, Uhura? I could change your mind.
      Uhura: You are away from your post, Mister!
      Mirror Sulu: Is the Captain here? Is Spock here? (amused) When the cat's away...

    • Mirror Marlena: Now I always thought that was funny: the great and powerful Captain Kirk who owes everything to an unknown alien scientist and a plundered laboratory.
      Kirk: Well, if you don't take advantage of your opportunities...
      Mirror Marlena: don't rise to the command of a starship.

    • Mirror Chekov: (with phaser aimed at Kirk): And so you die, Captain, and we all move up in rank! No one will question the assassination of a Captain who has disobeyed Prime Orders of the Empire!

    • Kirk: Shoot, you're wasting time.
      Mirror Spock: I shall not waste time with you, nor do I intend to simply disappear as so many of your opponents have in the past. You are too, inflexible, too determined once you've made up your mind. But Dr. McCoy has a plentitude of human weaknesses. Sentimental. Soft. You may not tell me what I want to know, but he will.

    • Mirror Sulu: Mr. Spock has orders to kill you, Captain. He will succeed, apparently. You will also appear to have killed him, after a fierce battle. Regrettable, but it will leave me in command.

    • Kirk: Conquest is easy. Control is not.

    • Spock: May I point out that I had an opportunity to observe your counterparts here quite closely. They were brutal, savage, unprincipled, uncivilized, treacherous -- in every way, splendid examples of homo sapiens. The very flower of humanity. I found them quite refreshing.
      Kirk: I'm not sure, but I think we've been insulted.
      McCoy: I'm sure.

    • McCoy: (talking about Spock) Jim, I think I liked him with a beard better. Gave him character. Of course, almost any change would be a distinct improvement.

    • Kirk: In every revolution, there is one man with a vision.
      Mirror Spock: Captain Kirk, I shall consider it.

    • Kirk: If change is inevitable, predictable, beneficial, doesn't logic demand that you be a part of it? One man cannot summon the future. But one man can change the present. Be the Captain of this Enterprise, Mr. Spock. Find a logical reason for sparing the Halkans and make it stick. Push till it gives. You can defend yourself better than any man in the fleet.

    • Kirk: What are you doing here?
      Marlena: (stretching) Oiling my traps, darling.

    • McCoy: I'm a doctor, not an engineer!
      Scotty: Now you're an engineer.

    • The spiral drop earrings that mirror universe Marlena wears in this episode will later appear as part of Uhura's outfit in season three of the series.

    • This episode first introduces the "mirror universe" storyline in Star Trek which is continued in several episodes in at least a couple of the series' spinoffs. This mirror universe is also featured in Deep Space Nine's "Crossover", "Through the Looking Glass", "Shattered Mirror", "The Emperor's New Cloak", and with savage universe characters visiting the regular Star Trek universe in "Resurrection". Enterprise also featured a prequel to this episode/storyline with "In a Mirror, Darkly (Parts 1 & 2)."

    • One of the subtle differences in the I.S.S. Enterprise is that the computer voice is a male voice - voiced by John Winston, who plays Mr. Kyle.

    • Sulu wears a red uniform in the alternate universe. This makes him the only cast member to have worn all three colors of uniforms in the series.

    • Desilu No: 5149-39.

    • Diane Duane also wrote a novel, Dark Mirror which detailed a return to the Mirror Universe for Captain Picard and the crew of the Enterprise-D. It explains what happened to the mirror-Spock, but otherwise it is substantially different from the mirror universe that was presented in the DS9 and ST: Enterprise episodes.

    • The story of what becomes of the alternate Federation and the alternate Spock is told in a 1994 Deep Space Nine episode "Crossover."
