'The Phantom Planet' is an extremely dull and talky sci-fi quickie set in 1980, by which time (as in Gerry Anderson's 'UFO') we Earthlings have established a base on the moon (where the communications officer interestingly enough is played by a Japanese actress (Akemi Tami), although we see and hear very little from her).
Most of the music (plainly library material) is actually pretty good. And it's so far, so dull until we eventually arrive on the surface of the planet Rheton (actually an asteroid), which resembles an enormous Chicken McNugget. It's at this point that the film delivers it's one real surprise, which I won't divulge here as so many others have, as it has remarkably little bearing on anything else that follows.
The Rhetons' costumes look as if they were left over from a movie set in ancient Rome; while the sets and the duel fought stripped to the waist between the film's two alpha males over the heroine anticipate one of the cheesier episodes of 'Star Trek'. (Ironically, Angelique Pettyjohn, who memorably played gladiatrix Shahna in 'The Gamesters of Triskelion', here appears unbilled in a non-speaking part as one of the jurors.)
Rheton's elderly ruler, Sesom (Francis X. Bushman) explains the primitive drabness of their present existence by claiming that the ill-effects from the unprecedented amount of leisure time resulting from labour-saving technology were solved by abandoning modern technology and returning to the simple life (late 20th Century capitalism certainly did a good job of licking this particular worry, if little else). Not that we see much evidence of good honest toil taking up much of the time of those Rhetons that we actually meet; all twenty of them. (Maybe all the real work is being done by slaves.) Nor do we see any bookcases, so it presumably didn't occur to the Rhetons to use all that unaccustomed leisure to read or write books. Their frugal existence, however, hasn't stopped them from harnessing "the magnetic forces of Rheton" to create a hi-tech defence system against attacking enemy ships piloted by aliens called Solorites (in scenes which recall the climaxes of 'This Island Earth' and 'Star Wars'), and creating force fields within which to imprison a captured Solorite (played by an uncredited Richard Kiel) and 'disintegrating gravity plates' in the floor to vapourise anyone who stands on them.
