[1] The series did not deal with real characters in the history of Tombstone in the 1880s, such as Wyatt Earp, Doc Holliday, or the Clanton gang, with the exception of Curly Bill Brocius, who appeared in the first season.

Eastham, the only other actor besides Conway to appear in all the episodes, played Harris Claibourne, editor of The Tombstone Epitaph (an actual newspaper that still exists in limited form).

Eastham, originally a singer in opera and on Broadway, also narrated the series in a deep baritone voice,[2] describing each episode as an actual report from the newspaper's archives.

The previous year, Mohr had portrayed Holliday in an episode of Maverick titled "The Quick and the Dead" starring James Garner and Marie Windsor.

The ending credits indicate, "This series is produced with the full cooperation of Clayton A. Smith, editor of the TOMBSTONE EPITAPH and D'Estell Iszard, historian".
