Continuity: When Spock orders the phasers to fire, they shoot outward from the ship at an angle from each other, but when they hit the asteroid they converge at a single point. (Time)

Continuity: When Miramanee and her companion first see Kirk at the obelisk, the two women are standing, holding their fruit baskets, just inches from each other. In the very next, reverse angle shot, they're suddenly several feet apart. (Time) Submitted by Jean G

Continuity: The stardates of Starnes' entries are 5025.3, 5032.4, and 5038.3 But Kirk gives the stardate of when they arrive at the beginning of the episode as 5029.5, so apparently Starnes made two entries after he died.

Visible crew/equipment: When Kirk turns to follow Miranda across the arboretum, the camera shadow is briefly visible on the wall at the lower left of the screen. (Time) Submitted by Jean G

Revealing: The colorful nebulae of the energy barrier are showing through the hull of the suddenly-transparent Enterprise as it heads back into the galaxy. (Time) Submitted by Jean G

Revealing: During the fight in engineering, Marvick's kick, throwing one of the engineering crewmen violently back against the wall, misses by an obvious mile. (Time) Submitted by Jean G

Continuity: At the dinner for Miranda, Kirk drains his glass. No one refills it, but it's nearly full again a few shots later. (Time) Submitted by Jean G

Factual error: The Enterprise accidentally travels a short distance outside the galaxy and can't find its way back. But they'd have to travel for months to get so far outside the Milky Way that they couldn't, well, just turn around in the void and see it. Our galaxy is huge. 100,000 light years across. Very huge. And that barrier may surround the galaxy, but even it is big, pink and visible. Submitted by Jean G

Revealing: In the sickbay scene near the end, someone got their line wrong, resulting in this contradictory bit of 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." (Time) Submitted by Jean G

Continuity: Kirk aims his phaser at a berserk Spock's head and fires, but the beam hits him in the stomach.

Continuity: When Chekov sits outside the general store chatting with Sylvia, his left arm and her right alternate from entwined to un-entwined and back again as the shots change. (Time) Submitted by Jean G

Factual error: Kirk's line, "We're a doomed ship, traveling between galaxies" is the only time original "Trek" committed the scientific blunder of confusing galaxies and solar systems. The Enterprise wasn't capable of intergalactic travel (that's leaving one galaxy and reaching another). Yes, it strayed briefly out of our galaxy several times. But it did not - and could not - cross to another one. That would take a warp 100-plus drive and thousands of years. (Time) Submitted by Jean G

Continuity: At the end when the entity left the Enterprise, it came out of the secondary hull, however it left from the engineering dept. The Engineering dept. is located in the back of the primary hull.

Continuity: In the opening scenes, Sulu's retractable viewer isn't there when the Klingon ship approaches on the view screen. But a moment later in a closer shot, the viewer is suddenly in front of him, fully extended. (Time) Submitted by Jean G

Continuity: Natira orders the landing party to kneel before the oracle. Spock does so about a foot-and-a-half to McCoy's left. As the shots change, Spock "jumps" to McCoy's immediate side, then back to his original position, etc. (Time) Submitted by Jean G

Continuity: After he falls unconscious onto the blue rug, McCoy's position relative to the rug's top edge keeps changing between shots. (Time) Submitted by Jean G

Continuity: Kirk calls Scott to beam up, and lowers the communicator from his face as he looks at McCoy. In the next shot, he's holding it to his mouth once more. The shot changes one more time, and it's lowered again. (Time) Submitted by Jean G

Continuity: Kirk orders Sulu to match speed with the asteroid, but in the next external shot the asteroid is closing in on the ship.

Visible crew/equipment: A camera shadow briefly intrudes on the right side of the screen as Kirk asks Mr. Scott about the sensor readings. (Time) Submitted by Jean G

Revealing: McCoy's stunt double's face is visible several times during the fight with the berserk orderly in the sickbay lab. (Time) Submitted by Jean G
