  • Kirk, McCoy, Uhura, and Scotty are transported by mistake to a parallel dimension on an alternate, savage Enterprise.

  • Spock sports facial growth, Uhura flaunts some toned abs, and Sulu is genuinely creepy in both universes.

  • A transporter malfunction during an ion storm has Kirk, McCoy, Scotty and Uhura swapping places with their counterparts in a parallel universe, where officers try to assassinate their superiors to better their rank. For many years, my favourite episode...

  • Uhura turns down date with Sulu and claims it had nothing to do with the 8 inch scar running down his face

  • Quotes (15)

    • 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: ...you don't rise to the command of a starship.

    Notes (8)

    • Foreign episode titles: "Mirror" (France) "A Parallel Universe" (Germany); "Terror of the Ion Turbulence" (Japan); "The Mirror" (Portugal); "Mirror, Little Mirror" (Spain).

    • 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.

    Trivia (20)

    • 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.

    • Title References the line "Mirror, Mirror on the wall, who is the fairest of them all?", from the children's fairy tale Snow White and the Seven Dwarves.

    • Evil Twins: Beards
      This episode set the standard for any television show where the main character has an evil twin and denotes it by the evil character sporting a goatee.
