Critic Reviews for Invasion of the Neptune Men
Yikes, but this is an howler. Some aliens from Neptune want to invade Earth, but luckily we have "Space Chief" in his slightly enhanced version of "Chitty Chitty Bang Bang" and his gang of weans. Even more fortunately, the Neptunians are pretty hopeless at the old invasion lark and the planet is in no more danger of domination than we are of being entertained. The production is too bad to be basic, the acting likewise and the whole thing a total waste of celluloid - but, it did make me smile now and again.
