This is the only episode where Will pilots the Jupiter 2 from one planet to another without help from his father or Major West.
This episode is unique in that there is a brief commercial break in the fourth act. It starts with Will being thrown out of his hiding place in front of the John and Don duplicates. Next comes a freeze frame with the message DON'T GO AWAY - BACK IN A MINUTE. The action unfreezes after the break.
The robot quotes Luke 4:8 to Will Robinson - "Get thee behind me."
When Dr. Smith is being escorted from the elevator by the duplicates John and Don, he is carrying a travel bag from United Airlines with the logo covered up.
The episode title in the opening credits is an a different font than has been used in any previous episode.
