Quotes (11)

  • Janice Rand: (startled) Oh! Captain. You startled me. Is there something that you... can I help you, Captain? Animal Kirk: "Jim" will do here, Janice.

  • Kirk: (his two halves reunited) Thank you, Mr. Spock - from both of us.

  • Sulu: (freezing on the planet's surface) Any chance you can lower us down a pot of hot coffee? Kirk: I'll see what I can do. Sulu: Rice wine will do if you're short on coffee.

  • Spock: (speaking softly to Yeoman Rand) The impostor had some rather interesting qualities. Wouldn't you say, Yeoman?

  • Spock: If I seem insensitive to what you're going through Captain, understand--it's the way I am.

  • McCoy: You have a point, Spock? Spock: Yes. Always, Doctor.

  • Spock: (to Captain Kirk) You're the captain of this ship. You haven't the right to be vulnerable in the eyes of the crew. You can't afford the luxury of being anything less than perfect. If you do, they lose faith and you lose command.

  • Kirk: I have to take him back inside myself. I can't survive without him. I don't want to take him back. He's like an animal. a thoughtless, brutal animal. And yet it's me. Me!

Notes (3)

  • The original script called for Spock to "karate" chop the evil Kirk at one point. Leonard Nimoy felt the action was too violent for a pacifist character, and so developed the famous "Vulcan Nerve Pinch" instead.

  • This was originally scheduled to be the fourth episode.

  • This episode marked the first appearance of Kirk's alternate green uniform. It was introduced primarily to tell the "good" Kirk from the "evil" Kirk. However, the producers liked the idea of setting the captain apart with a different colored uniform so they used it frequently throughout the series.

Trivia (27)

  • Why don't they just beam up the landing party and have a security team standing by to subdue the "evil" versions when they come through? It would buy time to find a solution, and even if no solution is found, wouldn't dying as split good and evil parts be preferable to freezing to death?

  • When "evil" Kirk blasts the panel in Engineering, why do Spock and "good" Kirk not report it to a repair crew, but instead, have Scotty stumble on to it later?

  • When "good" Kirk and Spock step into the transporter to go to sick bay, there is slight jump in the frame before "evil" Kirk's blood-stained hand thrusts onto the screen - revealing the cut that allows William Shatner to be in two places at once.

  • Apparently, the transporter isn't just giving Kirk split-personality problems; when Spock goes to reunite Kirk's two halves, watch him as he engages the beam and you will see his head and upper body vibrating, as though he were going to split in two.

  • When beamed up (and before on the planet) the Kirks had no chest insignia on their uniforms, yet as they both started to wander the ship, the insignia was present on both with no time for either to have got changed. Indeed, the first place good Kirk goes is to his quarters at which point he changes into the green uniform, but this was after the insignia had appeared.

  • On the bridge, Navigator Farrell's uniform goes from bearing the Enterprise chest insignia when Spock leaves, to having none when evil Kirk arrives, yet in that same scene, the insignia is present again when Farrell turns around to face evil Kirk.

  • When the evil Kirk makes the good Kirk drop his phaser during their fight, it falls behind evil Kirk. He then just bends down and picks it up, without having to back up or turn around to find it.

  • McCoy keeps talking about the "autopsy" on the dead alien dog, but autopsies are only done on humans. The term he should've used was necropsy.
