Episode complete credited cast:
Will Robinson (as Billy Mumy)
The Ruler


The Robinson party meets Quano, a stoic twelve-year-old alien boy from a warrior race who's on the planet for a survival challenge. Since Will is near his age, a fight-challenge is offered. Will has no interest in fighting without reason, but Quano wants the challenge, in part to prove his superiority but also to prove his worthiness as heir apparent to his often-absent father, ruler of their male-dominated race. Quano finally goads Will into accepting, but Will doesn't know that, if he wins, Quano's family with have to destroy him and all witnesses. Dr. Smith surreptitiously learns of this and, threatened into silence, works to wear Will down with over-training before the contest, to save their lives. Written by statmanjeff

Did You Know?


Part of the costume for the creature in the cave that Quano challenges is obviously the head from 20th Century Fox's earlier The Fly (1958). See more »


At the beginning of the episode Will and Dr. Smith are monitoring an intruder alert system, but in earlier episodes it is shown that the Jupiter 2 has a force field that can be deployed meaning that the intruder alert system would have been unnecessary. See more »


Prof. John Robinson: Is your father with you?
Quano: No. He is The Ruler. He is too busy.
Maj. Don West: What does that mean, Quano, "He's the ruler?"
Quano: In your world there are presidents, kings and dictators. In mine there is only one - The Ruler.
Dr. Zachary Smith: Are you telling us that... your father is the... the LEADER of your planet?
Quano: My command will be law.
Maj. Don West: Well, what do you know? We're entertaining royalty.

Kurt Russell
14 February 2015 | by See all my reviews

John and Will must battle it out with a couple of aliens, played by Michael Ansara and Kurt Russell.

A few years ago Kurt Russell was shown footage of himself in The Challenge on a US talk show. Russell had to hold back laughter and made fun of his own "bad acting". Today, when I watch this episode I remember that interview.

At one point in The Challenge Ansara makes a very sexist comment about women's duties on earth to which Don responds "I can see the boys at the club (on his planet) laughing about it now". Funny stuff.

The Challenge was more fun when I was a child of the 1970s but it still has the odd moment I can enjoy as an adult. I read somewhere that Ansara was originally offered the role of the hunter alien in season three's - Hunter's Moon - but the role went to cheaper to pay actor, Vincent Beck.
