He wrote a short story, "The Whipsaw," for the 11 Aug 1934 issue of Liberty, which was turned into a movie with Spencer Tracy and Myrna Loy launching his screenwriting career.
Grant wrote numerous short stories that were published in Argosy, The Saturday Evening Post, Cosmopolitan, and Liberty, among others.
[2] He also wrote a play Plan M. John Wayne called Grant "a dear friend", and said of him: He had a great talent as a writer.
He had to make the dialogue give character to a person and progress the story, and that's practically what Ford as a director did all the time.
[citation needed] Grant won the Bronze Wrangler, an annual award presented by the National Cowboy & Western Heritage Museum, twice, for The Alamo in 1961 and The Comancheros the following year.
