I am from Fort Smith, the purported locale of this film. This is my favorite movie of all time, but I can assure you that eastern Oklahoma looks nothing like the beautiful panoramas in this movie, too bad. The last of and the greatest western ever filmed. I cannot think of one after it that can match it. The "Old West" may never have really lived but it sure died around the turn of the century and its life on the silver screen died along with John Wayne. This movie was easily his pinnacle. As for Glenn being so bad, well he is from Arkansas, God Bless'im and he was forced to play the role of a Texan... tough.
