This episode marks the first appearance of the Space Pod, which allows the members of the Jupiter 2 party to travel "light" from time to time. Alas, no sooner has the Space Pod been activated than its mother ship is captured by menacing Androids, acting under orders from a huge, clocklike computer. In the course of ensuing events, the Robot is forced to become the leader of the androids, Dr. Smith (
Jonathan Harris) is transformed into a small boy--and horror of horrors, Professor John Robinson (
Guy Williams) is killed! ~ Hal Erickson, All Movie Guide
