Maverick 1957–1960
With Karen Steele in Maverick
After several feature film roles, including Sayonara 1957 with Marlon Brando, Garner got his big break playing the role of professional gambler Bret Maverick in the Western series Maverick from 1957 to 1960.
Only Garner and series creator Roy Huggins thought Maverick could compete with The Ed Sullivan Show and The Steve Allen Show but for two years it beat both in the time slot. The show almost immediately made Garner a household name.
Garner was the lone star of Maverick for the first seven episodes but production forced the studio, Warner Bros., to create a Maverick brother, Bart, played by Jack Kelly. This allowed two production units to film different story lines and episodes simultaneously, necessary because each episode took an extra day to complete, meaning that eventually the studio would run out of finished episodes to air partway through the season unless another actor was added.
Critics were positive about the chemistry between Garner and Kelly and the series occasionally featured popular cross-over episodes starring both Maverick brothers as well as numerous brief appearances by Kelly in Garner episodes. This included the famous "Shady Deal at Sunny Acres," upon which the first half of the 1973 movie The Sting appears to be based, according to Roy Huggins' Archive of American Television interview. Garner and guest star Clint Eastwood staged a fistfight in an episode titled "Duel at Sundown", in which Eastwood played a vicious and cowardly gunslinger. Although Garner quit the series after the third season because of a dispute with Warner Bros. he did make one fourth-season Maverick appearance, in an episode titled "The Maverick Line" starring both Garner and Jack Kelly that had been filmed in the third season but held back to run as the season's first episode if Garner lost his lawsuit against Warner Bros. Garner won in court, left the series, and the episode was run in the middle of the season instead.
The studio attempted to replace Garner's character with a Maverick cousin who had lived in Britain long enough to gain an English accent, featuring Roger Moore as Beau Maverick, but Moore left the series after filming only 14 episodes. Warner Bros. had also hired Robert Colbert, a Garner look-alike, to play a third Maverick brother named Brent Maverick. Colbert only appeared in two episodes toward the end of the season. That left the rest of the series' run to Kelly, alternating with reruns of episodes with Garner during the fifth season. Garner still received billing during the opening series credits for these newly produced Kelly episodes, aired in the 1961–1962 season, although he did not appear in them and had left the series two years previously. The studio did, however, reverse the billing, at the beginning of each show and in advertisements during the fifth season, billing Kelly above Garner
Garner played the lead role in Darby's Rangers 1958. Originally slated for a supporting role, he was given the lead when Charlton Heston turned down the part. He performed well as William Orlando Darby, who was approximately Garner's age during World War II. Following Garner's success in Maverick and Darby's Rangers, Warner Bros. gave Garner two more major theatrical films to be filmed during breaks in his "Maverick" shooting schedule. These were Up Periscope 1959 with Edmond O'Brien and the romantic drama Cash McCall 1960 with Natalie Wood.
