You know you're in for a pretty good B movie watching time when the title of the damn thing is actually used repeatedly! And so it goes with this hilariously plotted, ridiculous low budget disaster-piece. It's worth noting that the filmmakers themselves seem to have been all too aware of how absurd their monsters look, so they thought, "Why not show them right from the start?" Which is exactly what happens in this tale of subterranean prehistoric bipedal beasts who emerge from the sewers of Los Angeles to wreak havoc on the populace, sealing the city up with a wall of pure fog that later turns solid. A pilot, Tom Gregory (Robert Hutton, who also directs) hooks up with a professor (Robert Burton) and his hottie daughters (Susan Hart and Judee Morton) as well as a lone marine soldier (William Boyce) who turns up.
Hutton does what he can with his limited financial means, using the aspect of the fog to his advantage and getting some decent atmosphere. (However, there's simply too much fog in later scenes, and it's hard to make out the action.) As a director he never seems to take things too seriously, although as an actor, he keeps a straight face throughout, as do his co-stars. The standout in the cast is sci-fi veteran Les Tremayne, who's fun as Norman Tolliver, an outspoken author who dotes on a pet goat. When it looks like Normans' time is up, Tremayne actually looks legitimately terrified. Hutton creates a palpable sense of isolation in the first few minutes, before the professor and the daughters show up.
Bad movie fans should enjoy themselves watching this one.
