Yes, it was the Second World War that Audie fought in. When the war was over, thre was a best-selling book about his exploits titled To Hell And Back and they made a movie of it, starring Audie. I don't believe he had any previous acting experience, but he was handsome and did a passable job. He made several westerns after that, but his best and best-known movie was probably The Red Badge of Courage/
