Pony Express (TV series)

Pony Express is an American western television series about the adventures of an agent in the 1860s of the Central Overland Express Company, better known as the Pony Express. The half-hour program starring Grant Sullivan was created by California National Productions. "Pony Express" ran for thirty-five episodes in syndication from the fall of 1959 until May 1960.
Overview.
The series featured two recurring roles: Grant Sullivan as Brett Clark, a roving investigator for the company, and Don Dorrell as Donovan, a young Pony Express rider. The majority of the weekly episodes involved Clark and Donovan solving various Pony Express mysteries.
Production.
"Pony Express" was filmed at Iverson Movie Ranch in Chatsworth in Los Angeles County, California. It was one of several western-themed television shows produced by CNP, including "Boots and Saddles" (1957–1958) and "Union Pacific" (1959–1960) and "Frontier" (1955-1956). CNP created the series for the 100th anniversary of the actual Pony Express.
The "Pony Express" pilot was shot in February 1957 with James Best in the lead. This version did not sell (although Best was included in a "TV Guide" photo feature on upcoming TV westerns in June of that year) but was later aired, slightly re-edited, as an episode of the syndicated series.
