Giving this film a 6 out of 10 warrants some explanation, my vote reflects my taste for this genre of film-making; low-budget, disposable, 1960's drive-in films. That said, this particular example is quite distinctive and well worth a look. Made in the Philippines (around '62 or '63, I would guess, despite its official release date of 1971) on an obviously limited budget, the picture is wonderfully well photographed in black and white with some moody, noir touches. The lead, Robert Winston, is quite good-looking, albeit modestly talented. There are a surprising number (for this period) of beefcake shots. I'm assuming that someone recognized that his gifts were not in the acting department. The usual, grinding expository dialogue is graced with some humor, I LIKE the monster, the scenery is interesting and, on the whole, it moves along quite nicely. Shlock filmmakers of the present day (and they are legion) could learn a bit from the the achievements of these frugal talents.
