A One Man Game is a 1927 American silent Western film directed by Ernst Laemmle and written by William Berke.
The film stars Fred Humes, Fay Wray, Harry Todd, Clarence Geldart, Norbert A. Myles, and Lotus Thompson.
Just to see how much difference a few clothes will make, Hunter rigs himself out like a Broadway sheik and visits the Robbins ranch under the title, “the Duke of Black Butte.” With a clean shave he is completely disguised.
Hunter is so well pleased with his progress that he determines to win the young city woman or bust, much to the distress of Bobby, who is disgusted with his performance, but does not give him away.
When she dons some more traditional female clothing, it occurs to Hunter for the first time that Bobby is a woman, but he fails to take her seriously and makes a date with Milly to go riding at night.
