- Originally scheduled to be broadcast on November 22, 1963 but postponed due to CBS' coverage of the assassination of President John F. Kennedy.
- Although aired for the first time in January of 1964, this episode about the later years and murder of Wild Bill Hickock had originally been scheduled for November 22, 1963, the day that President John F. Kennedy was assassinated. It was, therefore, preempted by news coverage of history making events such as the return of newly sworn-in President Lyndon B. Johnson to Washington, D.C., escorting the widowed former First Lady Jackie Kennedy.
- Last show of the series.
