1957's "The Unknown Terror" was a production of Robert L. Lippert's Regal arm distributed by 20th Century-Fox, shot in Darryl F. Zanuck's new CinemaScope process under the working title "Beyond Terror" but redubbed RegalScope for these little 'B' pictures (other Regal efforts include "She Devil," "Kronos," "Ghost Diver," and this film's cofeature "Back from the Dead"). They only lasted three years before receiving a name change to Associated Producers ("Return of the Fly" and "The Alligator People" were among the first under this banner), but the week long schedule on a fixed budget of $100,000 apiece did not change. "The Unknown Terror" certainly looks poverty stricken, its depiction of a Caribbean island village consisting of one cramped street crowded with extras, starring John Howard ("The Invisible Woman," "The Undying Monster") as millionaire explorer Dan Matthews, determined to find his wife's missing brother lost in search of the fearsome 'Cave of Death' (which we see before the opening credits). The actual hero is Peter Morgan (Paul Richards, "Phantom of the Rue Morgue," "Beneath the Planet of the Apes"), who was crippled after selflessly saving Matthews from certain death, so Dan feels obliged to offer him the job of guide, his wife Gina (Mala Powers) insistent on coming with them. Things quickly take an ominous turn when the native who led the way to the tiny village disappears, the lone nearby American Dr. Ramsey (Gerald Milton) providing accommodations for the trio but remaining secretive about the dreaded cavern. There's a sacrificial altar, a fresh corpse (the victim's tongue already cut out), and death dealing islanders covered in fungus that the doctor has discovered; unfortunately, the special effects crew accomplished this by covering the actors in cotton wool and soap suds, which has earned the film a certain notoriety, though not enough to keep it from falling into near total obscurity after its 20 year TV run. This author confesses a nostalgic affection for this admittedly minor effort, despite the many questions that go unanswered, though it's no surprise to learn the fate of Gina's missing brother.
