Shivers is a kind of zombie movie, except that the zombies aren't out for brains, they're out to get laid. And they aren't really dead, but just under the influence of a parasite that unleashes their libidos and eliminates their inhibitions. It takes place in a high-rise apartment building on an island near Montreal, where a doctor has been experimenting with parasitic organisms that could potentially eliminate the need for transplants: Instead of having, say, a kidney transplant, why not remove the diseased kidney and replace it with a parasite that, in exchange for a small amount of the patient's blood, would perform all the functions of a kidney? But the parasite he's working with has the unfortunate effect of producing the symptoms described above -- which is fine with the doctor, because he thinks human beings are too sexually repressed. It's a clever premise for a horror movie, and totally in keeping with writer-director David Cronenberg's exploration in his films of the unfettered id. Unfortunately, it was made a few years before its time, so Cronenberg has to be more discreet in his depiction of the orgies of the victims of the parasite than he might have been a few years later, and the budget for the film was obviously scanty. It's shot in a rather muddy but garish color, and the lighting is flat and harsh. There are a few familiar faces -- of the "where have I seen him/her before?" order -- among the actors, but mostly it's a cast of hard-working unknowns. One of Cronenberg's first features, it's a good sample of the better-made horrors yet to come.
