Corrected entry: Kirk, McCoy, and Spock are chained to the dungeon wall, with McCoy noticing he is next to a skeleton, also chained. This is incorrect, as a skeleton's bones are held together by cartilage, which would rot over time. Therefore, the skeleton would not be hanging intact, but would be a pile of bones on the floor.
Correction: The dungeon and the skeleton are illusions specifically created to be frightening. Whether a real skeleton would remain intact is irrelevant.
Corrected entry: When Spock goes outside to scan the area he looks at the building directly in front of him, but when the child rubs away the dirt on the window Spock is seen looking at the ground to his right. But in the next shot Spock is looking directly at the building again.
Correction: When Spock comes out, and sends the guards off, he begins to look at, and scan with, his tricorder, and routinely glancing at the buildings, keeping mindful of possible attack in a possibly hostile situation. When seen through to cleaned spot, he is still performing the actions.
Corrected entry: Kirk orders Marple to cut around a rock to the right and make a noise to distract their observer. But the actor appears to slightly screw up his cue: Marple promptly traverses the rock to the left instead of the right.
Correction: Kirk indicated to Marple and Chekhov that someone or something was behind the rock that Spock nodded towards to show Kirk where their "friend" was. Kirk told Marple to "cut around the rock to your right", meaning the the man go around the indicated rock (behind Spock) so that his movements would be to his right, thereby keeping the rock to his right.
Corrected entry: When Nomad's bolt sends Scotty flying across the bridge, you can see the two rubber mats placed on the floor for the stunt man to land on.
Correction: There are no rubber mats anywhere for the stuntman to fall on. There was barely a second between impact and a person running to his side. He expertly landed in such a way as to avoid any major injury, save for a few bruises.
Corrected entry: When the android Kirk is created from the oddly short-legged blank, the turntable rotates to show Chapel the new Kirk - and the indentation on the other side suddenly disappears.
Correction: When the duplicator table turns for Chapel to see the new android Kirk, the indentations on both sides are there.
Corrected entry: Kirk informs Spock via communicator the Horta is ten feet from him, and Spock insists Kirk kill it. First, both know they cannot kill it with their phasers, and second, Spock's demand for Kirk to kill the Horta runs counter to the Vulcan philosophy of respect for all life. Spock would never want to harm, let alone kill, another life form.
Correction: At this point they don't have any proof that they can't kill it, and since Kirk is in danger, it's logical to try. Also, Spock is half human and he's concerned about his best friend being killed. Logical or not, he'll want Kirk to protect himself at all costs. Other episodes have shown where Spock doesn't always behave logically when his friends are at risk and he lets his emotions come out.
Corrected entry: We see our heroes paralysed by the alien belt machines, we then cut to the intro movie. When we go back to them they are being disarmed by the female alien. She takes something from McCoy's hand, yet before the intro he had nothing in his hands.
Correction: Rewinding more, you will find that there is an instrument in McCoy's hand, only concealed while wondering the arrived aliens.
Corrected entry: In the credits, Joan Collins' character is named "Sister Edith Keeler." But her character is engaging in a romantic/sexual relationship with Kirk. He says he has "ulterior motives" towards her which she reacts to playfully and kisses him. Not appropriate behaviour for a sister, particularly in the time and place the episode is set.
Correction: Edith Keeler wasn't a nun. She was a social worker, and thus, nothing she did would be considered inappropriate. She did work at the mission soup kitchen, where they would have called all women "sisters" just like they might call the men "brothers".
Corrected entry: When Plasus and two sentinels beam down to break up the fight near the mine, Plasus is on the end of the trio as they materialize. The camera angle changes as they step off the dais, and Plasus is suddenly in the middle.
Correction: When Plasus and the two sentinels are materializing on the landing pad, Plasus is between and behind the two sentinels (look at their feet in relation to the outer rim of the pad). The initial camera angle makes it a bit difficult to see, but the men are in fact positioned consistently during and after transport.
Corrected entry: Spock says they've only managed to punch holes in the force field large enough to fire through. But when the Enterprise fires, the force field (in the shape of Apollo's hand) is no longer there at all.
Correction: When the Enterprise fires on the temple, the force field IS visible. However, as they continue to fire and damage the power source, the force field starts to fade and flicker in and out, until it is gone.
Corrected entry: Spock wants Uhura to keep her eyes on the monitor every moment. (One fluctuation and Scott could die.) But he calls her name, making her turn away from the monitor and look at him, in order to tell her not to take her eyes off it.
Correction: Spock only gives her the instructions after Scott opened the access plate. Prior to that he gave no instructions for her to not take her eyes off the readings. Once Scott inserted the probe is when the magnetic readings needed to be monitored, calling Uhura's name and having her take her eyes off the monitor at that moment caused no danger (or plot hole error).
Corrected entry: It is easy to tell where the matte painting and live action area meet when Fox and the assistant appear.
Correction: How is this a mistake? Using matte paintings is a common technique used since the earliest days of cinema. There are many other examples throughout the series where they are used.
Corrected entry: In the sickbay near the end, Diana Muldaur got her line wrong, resulting in this contradictory dialogue: Kirk: "He'll die. But that's what you want, isn't it?" Miranda: "That's a lie!" Kirk: "Oh yes it is - you want him to die." Miranda's line was supposed to be, "That's not true," with Kirk's "Yes it is" contradicting her. As it stands, she claims it's a lie, and Kirk replies "Yes it is."
Correction: Kirk's reply of "yes it is" refers back to his statement of what Miranda wants - "that's what you want...yes it is, you want him to die". He's continuing his train of thought, not replying to her statement.
Corrected entry: Just how the Troglyte spy manages to leap over one of the cloud city's balconies to his death is a bit puzzling. Stratos City is held aloft by huge anti-gravity generators. An anti-grav field should, sensibly, extend far enough past the balcony railings to keep people from falling off. Surely the self-obsessed Stratos dwellers would extend that field, since they want to protect their own skins above all else.
Correction: This is not a plot hole. It is your judgment that the technology should work this way.
Corrected entry: Spock has been known to say that Vulcans don't lie. But in this episode, he backed up McCoy who was trying to spare Kirk's feelings. When asked by Kirk about the final taped orders he left them, Spock said that "The crisis was upon us and passed so quickly there wasn't time to view the tape." A bald faced lie.
Correction: Spock says "the crisis passed so quickly," and then trails off. He never says they didn't watch it.
Corrected entry: When McCoy is working on putting Spock's brain back it is obvious that his arms are too high up to be doing anything other than fiddling about with Mr Nimoys forehead.
Correction: Of course, the good Doctor would not be fiddling with Spock's forehead using his hands. He'd be manipulating mechanical servos (Waldos) or something analogous, since reconnecting neurons would require microscopic instruments and likely nanotechnology.
Corrected entry: At the end of the episode, 7 people beam back up to the ship, which should be impossible since the transporter only had 6 pads.
Correction: EACH transporter has 6 pads. Enterprise has more than one transporter (at least 4, I believe), so they can beam up 7 people, it's just that one will end up in a different transporter room.
Corrected entry: The landing party is out of contact with the Enterprise for two days because of the missing communicators. Wouldn't the Enterprise notice at some point and beam down some more, or make some other attempt to contact Kirk & Co.?
Correction: Before Kirk and co. loses their communicators, Kirk contacts the Enterprise and says that there should be no attempt to come down for fear of spreading the virus. The proof is they beam something down to Bones to help manufacture a vaccine.
Corrected entry: If the Enterprise made sure everything was corrected to just before they went back in time (before actually going back to their own future) then there should have been no reason for Kirk and Sulu to recover the audio and video evidence of their arrival in the first place, since they made sure they were never there.
Correction: They were unsure whether their sling shot experiment would work.
Corrected entry: The outcome of the court martial is already known before it happens. Since the captain's log is recorded after a mission giving a detail of what had taken place before the log was recorded, Kirk would not have been able to record his own log (as Captain) if he had been found guilty during the trial.
Correction: The outcome of the court martial is known to the viewers, of course. If Captain Kirk had been convicted, there would be no more episodes of the show. The point of the episode is to reveal the details of how he was acquitted, as they unfolded, and the Captain's Log is added later as a narrative framing device. This cannot be considered a mistake.
