Zeder on AllMovie

In this inventive psychological horror story from Italian director Pupi Avati, an aspiring novelist named Stefano (Gabriele Lavia) receives an old portable typewriter as a gift from his girlfriend Alessandria (Anne Canovas). One day while playing with the machine, he notices the impressions on the ribbon left behind by the previous owner and becomes curious enough to copy them down and find out what had been written on the typewriter in the past. Stefano is startled to discover that it was once owned by a noted scientist named Paolo Zeder (Luigi Costa), and that Zeder was working on a report on his theories about "K Zones" -- places where supernatural energy is concentrated so heavily that the newly dead will rise from the grave and walk among the living. Stefano sets out to find out the facts about the K Zones, and he discovers that the truth is horrifying indeed. Zeder was originally released in the United States as Revenge of the Dead, and it was marketed as a standard-issue zombie movie, where it predictably failed to find an audience until more thoughtful genre enthusiasts rediscovered the original Italian version several years later.
