The first half is a 43 minute film called Actor's Blood. Edward G. Robinson plays an older actor whose daughter is a current star but troubled. She dies at the start and the rest of the film is a who done it. This part is pretty good. The second film stars Eddie Albert and is a fairly silly story about a nine year old female author that writes adult love stories. This one is called Woman Of Sin.
