Star Trek

Spock's Brain - S3-E1

Factual error: In the opening sequence, Spock identifies the alien ship as possessing "ion propulsion" which he says is "unique technology." Scotty is similarly impressed and says, "They could teach us a thing or two!" Kirk later comments that "Advanced ion propulsion is beyond even our capabilities." However, even back in the 1960s, ion propulsion was physically feasible, while Warp propulsion was complete fantasy. Ion propulsion of any kind could never even reach lightspeed and would be incredibly primitive compared to Warp technology. In fact, we in the 21st Century have already developed ion propulsion, but it will probably take many hundreds or thousands of years to develop anything even close to Warp technology.

The Return of the Archons - S1-E21

Revealing mistake: The rocks pelting Kirk and the landing party when all hell breaks loose bounce when hitting the actors, the brick walls, and the concrete sidewalk.

Wink of an Eye - S3-E11

Revealing mistake: In the Enterprise lab, as a sped up Spock goes to move away from McCoy and Chapel, McCoy's eyes follow his movements rather than looking at where Spock was supposed to be after he "disappeared."

Movie Nut

Patterns of Force - S2-E21

Revealing mistake: As Kirk and company exit through the tunnel, the seams of the wall sections are visible.

Movie Nut

The Squire of Gothos - S1-E17

Revealing mistake: As Trelane takes a swipe at Kirk, he hits a tree branch. As it breaks away, the building material it was made from is revealed, rather than it being wood.

Movie Nut

The Squire of Gothos - S1-E17

Revealing mistake: In Trelane's castle, Kirk and Sulu are supposed to be frozen, but they slightly waver.

Movie Nut

The Enemy Within - S1-E5

Revealing mistake: As the Enterprise passes by the camera in the opening, as Kirk does the Log entry monologue, it's easy to tell where the studio lighting was positioned.

Movie Nut

Mirror, Mirror - S2-E4

Continuity mistake: As there were two screen used models of the Enterprise, when the ship is seen flipping from one universe to the other and back, the nacelles of the Imperial Enterprise have the solid red fronts with what appear to be antennae.

Where No Man Has Gone Before - S1-E3

Continuity mistake: When the ship approaches the galaxy edge Yeoman Smith is standing behind the captain's chair, but when Kirk orders Mitchell to, "Neutralize warp...hold this position," and also "Address intercraft," in Mitchell's closeups Smith has vanished - even in the shadows being cast, though she reappears in the next shot.

The Galileo Seven - S1-E16

Character mistake: In the scene when the shuttle is finally repaired and lifting off the planet, Spock asks "Fuel status?" and Scotty incorrectly answers "15 pounds PSI, sir. Approximately enough for one orbit." The correct answer would be simply "15 PSI" without the redundancy, as the P in PSI already signifies pounds. As an engineer Scotty would know this. (00:42:00)

Miri - S1-E8

Factual error: If this planet is a duplicate, an exact copy, of Earth, then Lake Okeechobee, the largest lake in Florida, is wrong. Seen from space, it is much larger and more distinct than the lake shown on this duplicate.

Miri - S1-E8

Other mistake: In the opening, the planet looks to be turning the same as Earth does. On the viewer it is turning correctly. However, it is too quickly to be accurate, assuming it is a copy of Earth. If so, at this higher speed, the days would be shorter. Also, the ship should be moving at such a speed as to see the planet moving in the opposite direction.

Catspaw - S2-E7

Continuity mistake: When Jackson materializes, you can see his eyes are open. After he falls, Kirk and McCoy see that his eyes are closed.

Movie Nut

Errand of Mercy - S1-E26

Continuity mistake: Kirk has a sunburn on his face and chest (it appears to end partway down his chest-most noticeable in the scene shortly after his identity is revealed to the Klingons). First of all, how does one get a sunburn while flying through space (and one that does not match the pattern of the uniform). If one wants to explain it away as being from a recent shore leave or Enterprise tanning bed, the issue still remains that the intensity of the sunburn changes as the episode continues.

Errand of Mercy - S1-E26

Deliberate mistake: When the Klingons post signs for their rules, they're printed in English. The Klingons have their own language, and people on Organia most certainly aren't English speakers. Even if the Universal Translator allows Kirk and Spock to hear in English, it wouldn't change the look of a sign.

Day of the Dove - S3-E7

Revealing mistake: Chekov covers Mara's mouth with his hand when he assaults her in the corridor. Kirk intervenes and throws Chekov against the opposite wall. Brown streaks form where Chekov's hands hit the wall, most likely from the brown makeup used to create Mara's skin tone. (00:32:20)

Charlie X - S1-E2

Continuity mistake: In Janice Rand's quarters, Charlie mentally throws Kirk and Spock against the wall. After they collide with it and slide down the face of the wall, there is a huge indention and crack where Spock hit. After a camera cut to Charlie, when the camera looks at Kirk and Spock again, there is no damage to the wall.

Movie Nut

Charlie X - S1-E2

Continuity mistake: In the Rec Lounge Spock is playing his Vulcan lyre. When Uhura starts humming, he looks up and drops his hands. When the camera goes in for a close up on Spock, his hands are in the playing position again, and he drops his left hand.

Movie Nut

The Immunity Syndrome - S2-E18

Character mistake: The officer at the helm is referred to as Lt. Kyle, and is named that way in the end credits. Yet throughout the episode, Captain Kirk keeps calling him "Kowel".

Obsession - S2-E13

Revealing mistake: When Kirk and Garrovick are fighting at the end, Kirk knocks him down. As he helps him up, Garrovick leans against a huge boulder and the papier-mache rock moves very noticeably.
