Kelly shared the lead with James Garner in one of the show's most-discussed 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 Maverick). Bart rescued Bret at the climax of "Duel at Sundown", in which Garner fought guest star Clint Eastwood.
