In the wake of The Alaskans, Moore was cast as Beau Maverick, an English-accented cousin of frontier gamblers Bret Maverick (James Garner), Bart Maverick (Jack Kelly), and Brent Maverick (Robert Colbert) in the much more successful ABC/WB Western series Maverick.
Sean Connery was flown over from Britain to test for the part, but turned it down.

Moore appeared as the character in 14 episodes after Garner had left the series at the end of the previous season, wearing some of Garner's costumes; while filming The Alaskans he had already recited much of Garner's dialogue, for the Klondike series frequently recycled Maverick scripts, changing only the names and locales.
He had also filmed a Maverick episode with Garner two seasons earlier, in which Moore played a different character, in a retooling of Richard Brinsley Sheridan's 1775 comedy of manners play The Rivals.
In the course of the story, Moore and Garner's characters switched names on a bet, with Moore consequently identifying himself as "Bret Maverick" through most of the episode.

Moore's debut as Beau Maverick occurred in the first episode of the 1960–61 fourth season, "The Bundle From Britain", one of four episodes in which he shared screen time with cousin Bart (Jack Kelly).
Robert Altman wrote and directed "Bolt from the Blue", an episode featuring Will Hutchins as a frontier lawyer similar to his character in the series Sugarfoot, and "Red Dog" found Beau mixed up with vicious bank robbers Lee Van Cleef and John Carradine.
Kathleen Crowley was Moore's leading lady in two episodes ("Bullet For the Teacher" and "Kiz"), and others included Mala Powers, Roxane Berard, Fay Spain, Merry Anders, Andra Martin, and Jeanne Cooper.
Upon leaving the series, Moore cited a decline in script quality since the Garner era as the key factor in his decision to depart; ratings for the show were also down.
Moore was originally slated to appear with both Jack Kelly and Robert Colbert in the series but by the time Colbert starred in his first episode, Moore had already left the series.
Numerous early publicity stills of Kelly, Moore and Colbert posing together exist, however.

Moore was still under contract with Warners, who cast him in The Sins of Rachel Cade (1961), making love to a nun played by Angie Dickinson, and Gold of the Seven Saints (1961), supporting Clint Walker.
He went to Italy to make Romulus and the Sabines (1961).
