I watched this in a double-bill with the like-minded 'The Wild Women of Wongo', and it was enjoyable and entertaining. I was curious because I had found, also in Mill Creek 50-packs (I think the same one, 'Nightmare Worlds', though it could have been 'Drive-In Movie Classics') Tallas' much-later 'Cataclysm', which, though low-budget, was atmospheric and decent, and the horror portmanteau 'Night Train of Terror', which had a condensed version of that film, much later directed by Tallas, in a collaboration with two others. I'm glad I saw this once, as it was charming and fun, but I was fortuna...
