The world premiere in New York City, New York on July 2, 1941 was attended by Alvin C. York and Gary Cooper, as well as producers Jesse L. Lasky and Hal B. Wallis and many well-known government and Army officials.
When Gracie is showing Alvin their new home, she claims it was bought for Alvin by the people of Tennessee. It was, in fact, the Rotary Club of Nashville which provided the home and the surrounding land. The home was also not waiting for York upon his return from Europe as portrayed in the film. The club purchased the property in November 1919, a year after the war ended and after Alvin C. York and Gracie were already married. The couple did not move into the house until Valentine's Day 1922.
York is called Sgt by officer who receives his captured soldiers and by the French who give him a medal. In New York at the Waldorf, his uniform coat sleeves show a corporal's insignia. Later, in TN, he is wearing a Sergeant's insignia on his uniform sleeve.
At the rifle range, after the first shot, York is given 5 rounds. He shoots the first into the target which is then covered by a white round paster. Then he shoots the next four into the paster. When the target is checked by the range personnel, there are 5 holes in the paster instead of 4.
