Corrected entry: Throughout whole episode, Nan's car doesn't have rear-view mirror. But in the very last scene, when she needs to see Hitch-Hiker in back seat, she uses rear-view mirror.
Corrected entry: The scientists, having carefully charted their course to Earth, state that it is an 11 million mile trip from their planet. Not likely. Mars is our nearest planetary neighbor, and it's over 34 million miles away at its closest orbital approach. There are no planets any nearer to Earth than Mars. This is one of the very few cases where Rod Serling simply failed to do his astronomy homework. (00:12:30)
Correction: The whole point is that a planet used to be 11 million miles away. They blew themselves up, planet and all.





Correction: Rather than using a rear-view mirror, she pulls down the visor and sees him in a mirror attached to its top side.
