Cimarron is a 1931 Pre-Code Western film directed by Wesley Ruggles, starring Richard Dix and Irene Dunne, and featuring Estelle Taylor and Roscoe Ates. The Oscar winning script was written by Howard Estabrook based on the Edna Ferber novel Cimarron. It was RKO's most expensive production up to that date, and its winning of the top Oscar for Best Production is also one of the few Westerns to ever win the top honor at the Academy Awards.
