Synopsis

Near the end of the 19th century, Prof. John Mayer and his assistant, the scientist Dr. Isabel Reed, accidentally invent a powerful ray. An alien travels to Earth to destroy the machine since it would be a threat to the universe. He initially possesses the mind of Thomas, a sex maniac and serial killer, to get close to Mayer during the demonstration of the machine to scientists and the military. Mayer's niece, Laura, meets an acquaintance of her uncle, the chemist Dr. Paul Rosten, and Mayer invites him to join the research. When Thomas gets close to Mayer, the alien also possesses his mind in order to destroy the device and his notes. Meanwhile, Thomas is not able to control his murderous impulses and attacks several women with a straight razor.

Sci-Fi Cinema in the 1970s

Science fiction movies from the seventies (1970-1979), including TV movies as well as stand-alone mini-series. This list uses a fairly strict definition of science fiction, and therefore does not include most films that deal with fantasy, the supernatural, or super heroes. Films that fall more under the umbrella of horror (like a lot of zombie and pandemic films) have also been omitted.
