Continuity mistake: 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. (00:31:55)Jean G
Continuity mistake: 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. (00:10:35)Jean G
Continuity mistake: Kirk orders Sulu to match speed with the asteroid, but in the next external shot the asteroid is closing in on the ship.
