Star Trek (1966) - 86 mistakes in series 1

Continuity: When Rand brings Sulu the plate of food, it has a bowl of colored cubes on it. Then there's a cut to a close-up of Sulu eating the cubes and the bowl is now a plate. Then in the long shot it's a bowl again.

Continuity: When they first arrive on the planet, the tricorder Kirk is holding for McCoy starts on his left shoulder, disappears in the next shot, then in the next shot after that reappears in his right hand.

Other: Spock and McCoy have a brief argument over whether Charlie could have survived on his own all those years. Because they're talking at the same time, Spock saying "Doctor" as McCoy says "Mr. Spock," the closed captioner apparently misunderstood McCoy's line. The caption has him calling Spock "Dr. Spock."

Continuity: Kirk first says the Antares is a cargo vessel, but after it explodes he calls it a science probe vessel.

Continuity: When Capt. Kirk and Charlie enter the turbolift heading for the bridge, Kirk is wearing one style of tunic and when the turbolift arrives on the bridge, Kirk is wearing a completely different tunic.

Visible crew/equipment: In the scene where Dr. Dehnar is talking to Gary Mitchell in sick bay, when he grabs her arm you can see the shadow of the boom mike on the door and adjacent wall.

Continuity: When Kirk is fighting Gary Mitchell, his tombstone reads James R. Kirk. Kirk's middle name is Tiberius. Mitchell is a friend of long standing and would not have got it wrong.

Continuity: Initially, the Enterprise orbits Psi 2000 as the planet turns westward. But in later shots, on the bridge view screen, the planet has reversed directions and now turns eastward.

Continuity: As the bridge crew monitors Psi 2000 on the view screen, a glitch in the special effects matte makes the planet vanish briefly and then reappear - twice.

Continuity: Lt. Joey said to Lt. Sulu "You don't outrank me and you don't have pointed ears" but Joey is a junior grade lieutenant so Sulu would outrank him.

Continuity: Spock records a log entry as the "second officer". It appears they got "first officer" confused with "second in command."

Revealing: When Kirk beams up from the planet, the insignia on his shirt is not there.

Continuity: All during the episode there are scratches on the left cheek of the "evil" Kirk. When the "Good" Kirk and the evil Kirk confront each other on the bridge, there's a shot where the scratches are on the right cheek of the evil Kirk.

Continuity: Near the end, when the evil Kirk is confronting the good Kirk on the bridge and we see him in a close-up, the scratches on his face are on his right cheek. This is wrong because Yeoman Janice Rand had scratched him on the left cheek.

Continuity: As the women are beaming aboard in the transporter room, McCoy's uniform switches from the standard blue tunic to his short-sleeved medical smock and back again between shots.

Continuity: Kirk's says that it is Stardate 1329.8 in his opening log entry when the ship is in pursuit of Mudd's vessel. But after Mudd and the women have been brought aboard, Kirk's next log entry says that it is Stardate 1329.1.

Continuity: 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.

Continuity: When the android Kirk boards the Enterprise and takes a "command pack," he walks out and down to the transporter, but he doesn't have the pack in his hand.

Factual error: If Miri's planet is a "duplicate" (meaning identical) Earth, it should have clouds. It doesn't. This remains a mistake because "duplicate" means "exactly the same," and thus the clouds should be there. The special effects crew forgot to put them in. Noteworthy: the very first thing fixed in the digitally enhanced version of this episode was the duplicate Earth. It has clouds now.

Continuity: The dust smudging both Spock's uniform and that of the older security guard instantly vanishes when they walk out of the building to go look for the onlies.
