Wayne always said “Red River” was his best film. I probably agree but “The Man Who Shot Liberty Valance” was close. Also “Quiet Man” was a great one.
The John Wayne film I’d most like to see is “Girls Demand Excitement” (1931), which Wayne co-stars with Virginia Cherrill, who played the blind girl in Chaplin’s “City Lights” that same year. Also features Marguerite Churchill, who’d appeared with Wayne the preceding year in “The Big Trail.”
