On Petrie's Island, a small Irish island with no telephones and limited transportation to the mainland, Dr. Philips is doing secret work in a chemical lab to find a cure for cancer by creating living tissue that can fight and kill cancer cells, but as an experiment reaches a climax, there is an explosion. Farmer Ian Bellows hears odd noises coming from a cave and goes to investigate but doesn't return. His body is found by Constable Harris, but it's all soft tissue, with the bones completely sucked out—Harris tells Dr. Landers that Ian's face is "a horrible mush with the eyes just sitting on it" (though when we actually see the body, it's not quite as horrible looking as that description would have it). Landers goes to London and gets pathologist Brian Stanley and brilliant young scientist David West to come to the island to investigate. They assume a disease is to blame, but when they visit Philips' lab, they find Philips and his associate dead and similarly boneless. A farmer's cow is found dead in the same condition, and West deduces that the failed experiment created a new creatures which they call silicates that feed off of calcium phosphate, which is found in bones. After a couple of almost-reveals, we see these creatures: they are large turtle-like beings with a snake-like tentacle that grabs people and starts the process of deboning. They can also split in two, which they do at a rapid rate, possibly able to cover the island in just a few hours. The constable is killed by one, as is Dr. Landers when he tries to dispatch one with an axe (which is unable to penetrate its body). Campbell, the town's leader (maybe the mayor but that’s never made clear), and his assistant Argyle, put themselves at the disposal of West and Stanley, and soon it's figured out that radioactivity is the only thing that can kill the silicates. West and Stanley go back to Philips' lab to get some Strontium 90 (in an unnecessarily long scene showing the two suiting up in protective gear); the men have Campbell gather the islanders at the town hall while a bunch of cattle are injected with the radioactive element, the hope being that the silicates will eat the cattle and then die off. Unfortunately, if this doesn't work, it means the islanders are all potential food for the monsters.
Hammer director Terence Fisher made this film for Planet Film Productions, a short-lived outfit specializing in sci-fi horror. The movie starts off well; the feel of the island is authentic and most of the performances are appropriately low-key. Peter Cushing is his usual reliable self as Stanley and Edward Judd is quirkily handsome and commanding as West. His girlfriend Toni (Carole Gray) tags along though the narrative implies that Toni may have just been a one-night stand; it’s not really important but still a weird plotpoint. The supporting actors are surprisingly good at being innocent folks caught up in the quickly growing and potentially apocalyptic situation. They include Sam Kydd (the constable), Eddie Byrne (Landers), Niall MacGinnis (Campbell) and James Caffrey (Argyle). The creatures are a bit silly looking in the beginning, especially when they are indoors and move about like big Roombas. Outdoors they are fairly effective, and even more so when they drop out of trees or smash through windows, and the climatic scene at the town hall has a nice CRAWLING EYE feel. Overall, though, the whole thing has a bland look and a predictable by-the-numbers approach to narrative. The movie ends with the menacing creatures all wiped out. The usual "Don’t tamper in God’s domain" message is undercut a bit when West notes that "science has its risks but the risks aren't enough to hinder progress," but a last shot of a Japanese lab subverts that by providing a Gotcha! moment. BTW, a later Planet movie, NIGHT OF THE BIG HEAT, is very similar to this in setting and plotpoints, with the same director and with Cushing as a star. In fact, when I started watching this, I thought it was BIG HEAT which I'd already seen and almost stopped watching. Pictured are Judd, Gray, and Cushing. [Blu-ray]
