TERROR IS A MAN 1959 (SINISTER CINEMA)

Very well made Philippino horror film that actually was such a huge hit it spawned many similar types of movies for years to come.
Francis Lederer is a scientist who is attempting to change a panther into a human. These experiemnts have taken their toll of his gorgeous wife played by the always sexy Greta Thyssen.
Our story becomes even more intersting when a man washes up on shore and we learn he is the only survivor from a shipping disaster. Richard Derr plays the role very well and he actually shows interest in the experiments for a while until he decides the doctors lonely wife needs more attention.
The mutant being gets loose and goes on a killing spree and the makeup is quite good. The movie also had a warning bell that sounded when the doctor slices the neck of the creature open during a surgical scene.
If you like understated horror, you'll like this film and then you'll enjoy other Philippine made horrors as well.
