to featured roles in two Randolph Scott Westerns: Fighting Man of the Plains (1949), where he played Jesse James, and The Cariboo Trail (1950). Popular acclaim to Robertson's brief roles led him to be signed to a seven-year contract to 20th Century Fox. Robertson's first role for Fox was a support part in a Western, Two Flags West (1951). He had a support part in the musical Call Me Mister (1951). He soon advanced to leading roles in films such as Take Care of My Little Girl (1951), where he played Jeanne Crain's love interest, and Golden Girl (1951), where he supported Mitzi Gaynor. Stardom Fox gave Robertson top billing in Return of the Texan (1952). He appeared opposite Anne Baxter in The Outcasts of Poker Flat (1952), and starred in the historical adventure Lydia Bailey (1952). Robertson was never very cooperative with the press, even shunning the powerful columnist Louella Parsons. As a result, he won the press' Sour Apple Award for three years running. But then, commented Robertson, "that dang Sinatra had to hit some photographer in the nose and stop me from getting my fourth." He was one of several Fox names in O. Henry's Full House (1952) and was Betty Grable's love interest in The Farmer Takes a Wife (1953). RKO borrowed him for Devil's Canyon (1953) with Virginia Mayo and Son of Sinbad, filmed in 1953 but not released for two more years. He returned to Fox for City of Bad Men (1953) with Crain; The Silver Whip (1954) with Rory Calhoun and Robert Wagner; and The Gambler from Natchez (1954) with Debra Paget.
