This creepy yet clunky sci-fi-horror flick boasts one of the coolest monsters ever to grace the silver screen -- radioactive silicone beings ("silicates") that suck the calcium right out of your bones. They look like a cross between giant turtles, ostriches, and octopi, and they reproduce asexually every few hours by splitting in half and spilling out their glowing, spaghetti-like innards. With the exception of these creatures du jour and the eerie electronic sounds that emanate from them, Island of Terror is a fairly standard-issue lab-coats-versus-creatures flick in the mold of superior genre fare such as 1954's Them. A host of venerable British character actors, led by Peter Cushing and supplemented by saucy horror starlet Carole Gray, enliven the proceedings with their tics, their wit, and their willingness to throw their convictions behind stock suspense plot twists and low-budget special effects. A Saturday-afternoon creature-feature favorite, Island of Terror also boasts one of the most memorable amputation scenes ever.
