Fans of sci-fi and horror will be very pleased by the lavish, loving attention bestowed upon this 1959 Italian production, pustules and all. Inspired largely by The Quatermass Xperiment (1955) without being as smart, this is a movie that probably nobody will place among its decade’s top 10 sci-fi horrors. Nevertheless, it’s well worth a look and historically important for reasons we’ll mention.
The film opens with oodles of atmosphere conjured out of glass matte paintings, roiling volcano effects (actually, ink in water) and sheer shadowplay. We’re allegedly in Mexico, investigating the ruins of a Mayan civilization, when a member of the Ulmer expedition (named slyly for Edgar Ulmer, a master of cheap but effective atmosphere) staggers back to camp gibbering and fainting. The other members quickly discover the cave of Caltiki, a Mayan goddess, where some kind of radioactive blob emerges from the water to melt the flesh from impertinent explorers, especially those greedy for gold and nookie.
