This is one of those simple sci-fi prehistoric films which do no harm. Normally, they’re taken either dead seriously or as send-ups. This one quite deftly combines the two angles.
What the story (mainly shot in the Canary Islands) is all about is subject to doubt since Val Guest, who both directed and wrote the original screenplay, has elected to invent a ‘prehistoric’ lingo for the dialog.
Story concerns a huge upheaval in the Sun at the Dawn of History, resulting in a fiery, sullen appearance of the Moon. A blonde (Victoria Vetri) is blamed for this, her golden tresses having suspectedly insulted the Sun. She’s condemned to death, but is rescued by a neighboring Sand Tribe. The rest consists largely of fisherman Tara (Robin Hawdon) falling for the cutie, which irritates his girl friend (Imogen Hassall).
Amid the animals, special effects, and tribal rituals (and saddled with non-communicative language) the human thesps don’t stand much chance of scoring. There are a lot of very nubile, scantily-clad dames.
