The Keeper, a collector of animal specimens, comes to the planet to collect two of every kind. The Robinson party only becomes aware of his presence after Dr. Smith is ultra-sonically mesmerized into entering one of his cages. The Keeper, who can be as charming as he is condescendingly arrogant, eventually comes to see the Robinsons and thereafter sets out to add a couple of them to his collection. Written by
Did You Know?
Will wants to to know how The Keeper (Michael Rennie
) is able to speak English. He says that he learned it from listening to broadcasts he had picked up from Earth. Coincidental or not, this is identical to an explanation that Klaatu (also played by Rennie) gave in the classic The Day the Earth Stood Still
(1951). There is also a pattern of Rennie playing alien analogues of Biblical heroes: in "Day" his character was analogous to Jesus, in "Keeper" he serves the function of Noah. See more
When the Keeper first appears to the group of space travelers and walks up to them, he asks Will "[is there] Something wrong?" At that time Will is leaning over the cage, his forearms resting upon it. Then the image transitions to a two-shot close-up of Will and Penny, and Will is suddenly standing upright. See more
Are you out hunting for animals, Mr. Keeper?
In a manner of speaking, yes.
