Maverick (1957–1962)
The various anti-heroic Mavericks were dapper professional poker-players roaming the Old West with the benefit of superb scripts (at least in the first two seasons; the show gradually declined during the last three seasons). The series had an enormous cultural impact during a time when there were only three television networks and most American cities had only three TV channels to choose from.
Maverick's demanding filming schedule had caused production to lag behind early on. The producers decided to give Bret Maverick (James Garner) a brother so as not to run out of episodes long before the end of the season. Thus, Kelly was introduced as Bart Maverick in "Hostage", the eighth episode of the series.
Kelly shared the lead with James Garner in one of the show's famous episodes, "Shady Deal at Sunny Acres", on which the first half of the 1973 movie The Sting appears to be based. The pair also co-starred in the famous "Pappy" episode in which Garner played the brothers' much-quoted father Beauregard "Pappy" Maverick, in addition to his regular role of Bret. Aided by trick photography, Bret and Pappy play cards together in one scene (Kelly had a dual role in the episode as well, playing Bart and elderly Uncle Bentley "Bent" Maverick). Bart rescued Bret at the climax of "Duel at Sundown", in which Garner fought guest star Clint Eastwood.
Garner had first choice of which part he would play in the two-brother episodes, which delineated the brothers as "Maverick 1" and "Maverick 2" in the scripts, giving him an enormous advantage. All but one script during the show's first two years were written with Garner in mind regardless of which actor was being cast. Series creator Roy Huggins insisted that the writers visualize Garner as Maverick while writing the scripts, according to his Archive of American Television interview. The second-season episode in which Maverick was written with Kelly in mind instead of Garner was titled "Passage to Fort Doom".
Although the "solo" episodes in which Bart appeared tended to be somewhat more dramatic than the often more humorous Bret episodes, Kelly displayed his comedic skills in lighter Maverick outings such as "Hadley's Hunters" and "The People's Friend". Kelly actually appeared in more episodes of Maverick than James Garner, who left the show following a contract dispute in 1960 to successfully accelerate his theatrical film career. Kelly appeared in approximately 75 episodes due to his remaining for the entire run of the series; Garner is in 52 episodes altogether not counting introducing Kelly's earlier solo episodes in a separate frontispiece to ease audiences into the presence of a second Maverick during much of the first season.
In the wake of Garner's departure, Roger Moore played Bart's cousin Beau Maverick in 14 episodes, sharing the screen with Kelly in three of them, while Garner look-alike Robert Colbert appeared in two installments as a third brother wearing Bret's costume and named Brent, one of which briefly featured Kelly. The series was canceled after the fifth season, which consisted of Kelly appearing as the only Maverick in new episodes alternating with reruns of Garner shows from earlier seasons. The billing at the beginning of the show was reversed in the fifth season, with Kelly being billed above Garner. Kelly maintained that he was never notified of the cancellation by the studio but instead wound up learning about it in a newspaper article.
