When the librarian shows Mannix the newspaper on microfilm, she passes a couple of pages then tells Mannix "Here it is." Instead of stopping, however, she continues to scroll pass several more pages until she stops and again tells Mannix, "Here it is." Every page she has scrolled past has the exact same picture and caption at the top of the page while half of the pages have the same picture at the bottom of the page, the picture that Mannix ultimately is interested in.
When Tom the mailman brings the mail into Mannix' office he is carrying some newspapers and a tube container. When the scene changes to the interior of the office some letters magically appear between the newspapers and tube, one of which becomes the focus of the episode.
Includes an uncredited appearance by Frank Bonner as a man who is hypnotized in the nightclub scene.
