would become MGM's highest-paid actor within the next three years. Also in 1930, Brown played Joan Crawford's love interest in Montana Moon. Brown went on to make several more top-flight movies under the name John Mack Brown, including The Secret Six (1931) with Wallace Beery, Jean Harlow, and Clark Gable, as well as the legendary Lost Generation celebration of alcohol, The Last Flight (1931), and was being groomed by MGM as a leading man until being abruptly replaced on Laughing Sinners in 1931, with all his scenes reshot, substituting rising star Clark Gable in his place. MGM and director Woody Van Dyke screen tested him for the lead role of Tarzan the Ape Man but Van Dyke didn't feel he was tall enough. Steep decline Rechristened "Johnny Mack Brown" in the wake of this extremely serious career downturn, he made low-budget westerns for independent producers and he never regained his former status. Eventually he became one of the screen's top B-movie cowboys, and became a popular star at Universal Pictures in 1937. After starring in four serials, in 1939 he launched a series of 29 B-westerns over the next four years, all co-starring Fuzzy Knight as his comic sidekick, and the last seven teaming him with Tex Ritter. This is considered the peak of his B-western career, thanks to the studio's superior production values; noteworthy titles include Son of Roaring Dan, Raiders of San Joaquin and The Lone Star Trail, the latter featuring a young Robert Mitchum as the muscle heavy. A fan of Mexican music, Brown showcased the talents of guitarist Francisco Mayorga and The Guadalajara Trio in films like Boss of Bullion City and The Masked Rider. Brown also starred in a 1933 Mascot Pictures serial Fighting with Kit Carson, and four serials for Universal (Rustlers of Red Dog, Wild West Days, Flaming Frontiers and The Oregon Trail). Brown moved to Monogram Pictures in 1943 to replace that studio's cowboy star Buck Jones, who had died months before. Brown's Monogram series was immediately successful and he starred in more than 60 westerns over the next 10 years, including a 20-movie series playing "Nevada Jack McKenzie" opposite Buck Jones's (and earlier Wallace Beery's) old sidekick Raymond Hatton, beginning with the 1943 film The Ghost Rider. Brown was also featured in two higher-budgeted dramas, Forever Yours and Flame of the West, both released by Monogram in 1945 and both billing
