The Fantastic Journey's fifth episode, "A Dream of Conquest," is the first installment to open with a voice-over narration accompanying the opening credits. Mike Road (the voice of "The Source" in "Atlantium") now recounts the series premise. He also names and describes the main characters, and notes that our heroes -- now together -- "face the unknown."
In terms of the actual episode, I'd say that "A Dream of Conquest" is actually pretty strong, most notably because it is buttressed by a good, villainous performance from guest star John Saxon. Here, he plays Consul Tarrant, a "Materran" warlord who hopes to march East across the island and conquer all the time zones between his own, and land's end. In one splendid bit of series continuity, Tarrant asks Willaway about what he will find in the other time zones, and Willaway very pointedly and very specifically discusses the societies featured in "Atlantium," "Beyond the Mountain" and "Children of the Gods." For a series always shifting ideas, it's nice that The Fantastic Journey remembers its history.
Much of The Fantastic Journey's promotional material in the 1970s featured images of this kindly, shaggy alien. The creature suit looks pretty good, even today, except for the one horrid moment near the conclusion in which you can plainly make out the monster's socks...
In one horrifying sequence, Tarrant's soldiers use the Nephring in a military exercise, and Varian jumps into danger (and into the line of fire...) to save the creature's life.
Of course, the subtext here involves the human (and inhumane) treatment and abuse of animals. You shouldn't use them for target practice, and you shouldn't put them on the top of your family car either, when you go on vacation.
Okay, I made up the last part.
But of course, he doesn't really have any enemies. The other zones, as we have seen with our own eyes, are unaware of the Materrans, and either in ruins ("Atlantium," after the destruction of "The Source"), peaceful ("Beyond the Mountain") or woefully disorganized ("Children of the Gods.") In realizing this fact, we see just how petty and ridiculous Tarrant really is. He just wants to flex his muscles; to look like a "big man." He imagines enemies to conquer because of his own ego and desires, not because such enemies actually exist.
As Willaway says: "Ah, the generals. They are numerous, but not good for much."
This is abundantly true in "A Dream of Conquest" because none of Tarrant's subordinates stand up to the madman when he proposes and plans blatant aggression. A hierarchical structure is a good thing for maintaining order, no doubt, but a very bad thing when a madman rests at the top of the pyramid, perpetually unquestioned.
Although it's nice to see this now-retired ship again, the space shuttle is relatively small, and more than that, incapable of traveling from one solar system to the other. How did Materrans and humans develop the same ship (but with such different capabilities?) I can only guess that the prop master on The Fantastic Journey had access to a space shuttle model, and figured (since the craft was not yet in official use...) that no one would notice.
