The first original television series produced by a major Hollywood film studio Warner Brothers. (Some of "Disneyland", which had premiered the year before, did not really consist of programming made exclusively for TV).
Contrary to popular belief, 'Clint Walker' did not take his shirt off in every episode of "Cheyenne". For example, in the 15 shows which constituted the first season of "Cheyenne," Walker appeared bare-chested in only 6 of them: "The Argonauts", "The Storm Riders", "Rendezvous at Red Rock", "Quicksand", "Fury at Rio Hondo", and "Johnny Bravo".
Clint Walker had a contract dispute with Warner Brothers, which led to him briefly leaving. Under his contract, Walker had to give them 50% of his personal appearance fees, and could only record music under the Warner Brothers label. He wanted the amount cut, and to be able to sign with whatever record company he chose. The sides reached an agreement, and Walker eventually returned to work.
