When Bowen (Frank Lovejoy) tells the little girl in the store "Vaya usted con Diós", he tells Myers (William Talman) that he told her "Go you with God, little one". In fact, what he told her was simply "Go with God". The word "usted", meaning "you", is silent; it is not translated into English. And the words "little one" were not uttered at all, in either Spanish or English.
When Frank Lovejoy shoots the can from Edmund O'Brien's right hand with his rifle, the next scene shows the rifle with the hammer cocked which it would not be if he just fired the rifle. The rifle is a pump .22, not a semi-automatic.
