These "Mongol" bandits speak (rather poor) Mandarin Chinese rather than Mongolian, and the wrestling scene showed absolutely nothing of the famous Mongolian wrestling style. Other than that, I enjoyed the movie (shown on the Turner Classic Movies channel). It was a bit disappointing that Ford did not choose an East Asian to play the main "Mongolian" role - just as actresses like Katherine Hepburn played Chinese in movies like The Good Earth - but given the facts of Hollywood life at that time, this is understandable. An interesting subplot runs between the doctor and the head of mission: who is more Christ-like, she who talks the talk or she who walks the walk?
