Well... where to begin? Any remarks about the bulk of this film's content, i've already made in my review for "Voyage to the Prehistoric Planet", for in true no-budget tradition, Roger Corman and chums basically re-released the same movie (which was in itself a redubbed cannibalisation of the Russian space opera "Storm Planet"), with some newly-shot additional footage.
This new stuff entirely concerns the titular (in every sense!) women, the scrumptious Mamie Van Doren and assorted other leggy lovelies, lounging around the rocky shores of Venus in shell bikinis, eating raw fish, and emitting a curiously familiar siren song. If i were in a kinder - or drunker - mood, i might try to compare the way in which this film occurs 'in the wings' of the earlier movie to Stoppard's "Rosencrantz and Guildenstern are Dead". But i won't, for that way lies madness.
I need not have worried. As they pulled the magma-petrified remains of John the Robot from the mud and set him up as a shrine, i began to smile. One god's as good as another, after all. As another spaceborne robot, Marvin the Paranoid Android, said at the end of "So Long, and Thanks for All the Fish":
'You know... i think i'm quite happy about that'.
