Incorrect pronunciation: The narrator pronounces "Valance" with the accent on the second syllable, instead of (as John Wayne does in the film clip) with the accent on the first syllable. The name of the town of Llano, Texas, is "Lano", not "Lane-o". [Though many people, for whom English is a second language, pronounce words differently from native-born English speakers.]
