Star Trek: The Original Series - 03x23 All Our Yesterdays

Summary: The Enterprise is sent to evacuate a planet's population before a supernova occurs. Kirk, Spock, and Bones beam down to the planet, Sarpedon, to figure out why they can't detect any life forms. On the surface, they find a library run by Mr. Atoz and his clones who tells them that the entire population went back in time to escape the disaster... and then sends Kirk back to a 17th century era where he's taken for a witch, and Spock and McCoy to a frozen wasteland in the distant past.

MISTAKES/GOOFS

CONT: When Spock tries to use his phaser to warm a boulder at the base of the ice cliff, it doesn't work - presumably because phasers didn't exist in that time period. But when he lays McCoy out in Zarabeth's cave and examines him, the doctor's medical tricorder seems to work just fine.
CONT: when Spock, Jim and Bones meet the real Mr. Atoz he is sitting on a bench without any cushion. A few seconds later, when he offers Jim to sit on the bench, suddenly there is a cushion on the bench.
