Musical, Mahin retained most of the basic structure of the storyline, but little of Oscar Hammerstein II's stage dialogue, preferring to create his own. According to Kreuger, Mahin and producer Arthur Freed introduced the plot device of keeping the lovers Magnolia Hawks and Gaylord Ravenal young to the end, rather than having a passage that showed them forty years older, as in the original stage musical. He wrote Quo Vadis (1951) for MGM and My Son John (1952) for Leo McCarey. He redid his Red Dust script as Mogambo (1953) for Gable and John Ford, and worked on another melodrama in the tropics, Elephant Walk (1954). In 1955 a play he wrote with Patsy Ruth Miller, Don Ella, played at UCLA. Mahin wrote Lucy Gallant (1955), The Bad Seed (1956) for LeRoy, Heaven Knows, Mr. Allison (1957) for John Huston, and No Time for Sergeants (1958) for LeRoy. Heaven Knows, Mr Allison earned him another Oscar nomination. Mahin adapted Paint Your Wagon for Mayer but plans to film it were dropped when Mayer died. (It would be filmed in 1969 with a fresh script.) Mahin did do some uncredited work on the Cinerama film, South Seas Adventure (1958). Producer Mahin got to know Martin Rackin when they worked on a script of Pearl Buck's Letter from Peking, that was never filmed. They decided to form a production company. Together they wrote and produced The Horse Soldiers (1959), Revak the Rebel (1959) and North to Alaska (1960). The association ended when Rackin was appointed head of Paramount. Later career Mahin's later credits included The Spiral Road (1962) and Moment to Moment (1966) for LeRoy. He also wrote episodes of The Jimmy Stewart Show (1971–72).
