This entry (which has a copyright date of 1959, unlike the other nine which are dated 1958) has a slightly different introduction and conclusion compared to the other episodes. This and "Whatever Happened to Peggy" were thus the final Karloff shows completed before production shut down.
One of four episodes compiled for the feature Destination Nightmare (1958) - the others were "Whatever Happened to Peggy," The Return of Madame Vernoy (1958), and Girl on the Road (1958).
Some syndicated cable stations broadcast this episode under the alternate title "Heading 135."
