Matt Dillon (Gunsmoke) (whose "supposed" origins figured in the very first episode of the radio series), and he often referred to Wild Bill Hickok as being a close personal friend. In the television version (which ran from 1955 until 1975), and subsequent TV-movies (1987 to 1994), Matt was portrayed by James Arness. Since most of the early television episodes were based on stories and scripts from the radio version, Arness's initial interpretation and portrayal was similar to William Conrad's. However, as the television version continued, Arness's Marshal Matt Dillon evolved in a number of ways. In the television version, Dillon became more resigned
Matt Dillon (Gunsmoke) (Milburn Stone), and saloon-keeper Kitty Russell (Amanda Blake). These three individuals were among Matt's few real friends because he knew that he could trust them in any situation. In the television version, Chester was eventually replaced by Festus Haggen (Ken Curtis), an uneducated country-boy, but savvy plainsman who ultimately became a badge-wearing Deputy U.S. Marshal; a position that always eluded Chester. In both the radio and television versions, the exact nature of Matt's relationship with Kitty Russell was deliberately kept somewhat vague. Kitty was portrayed by Georgia Ellis in the radio version and by Amanda Blake in the television version.
