Pillow of Death 1945 was the last of the Inner Sanctum mystery films. The movie stars Lon Chaney, Jr. and Brenda Joyce, was directed by Wallace Fox, and based on a story by Dwight V. Babcock. The Inner Sanctum franchise originated with a popular radio series and all of the films star Lon Chaneys son. It was the only entry in the series to dispense with the introduction by a disembodied head in a crystal ball, as well as the only one to feature comicrelief characters to alleviate the grim tone.
