Among the highlights for old school Western fans of Get TV's Saturday Western block is 1958's Cimarron City, which starred George Montgomery (doubling as a producer, as his company co-produced the show with Revue) and John Smith, among others. Three weeks in, Dan Blocker, still better known for Bonanza, which came after Cimarron had been cancelled, joined the cast as Tiny, a ranch hand.
So why did it fail? It aired opposite CBS' 1-2 punch of Have Gun...Will Travel & Gunsmoke. Enough said. Didn't help that the 3rd lead, Audrey Totter, left the show because the writers didn't create enough storylines where she would be the lead.
