"The Unforgiven" was Audrey Hepburn's only Western.
Audrey Hepburn was seriously injured when she was thrown by a horse between scenes. Hepburn, who was several months pregnant, spent six weeks in the hospital and completed her role wearing a back brace, which her wardrobe had to be redesigned to hide. Sadly, she suffered a miscarriage a few months later, which some blamed on her injury from this movie. John Huston blamed himself for the mishap and hated this movie. Hepburn, however, bore no ill will towards the director. While Hepburn was in hospital, Huston filmed scenes using a double.
Average Shot Length (ASL) = 8.7 seconds
Before filming began, director John Huston and star Burt Lancaster took actress Lillian Gish out to the desert to teach her how to shoot, which she would have to do in the film. However, Huston was astounded to discover that Gish could shoot more accurately, and faster, than both he and Lancaster, who thought themselves expert marksmen. It turned out that early in her career Gish was taught how to shoot by notorious western outlaw and gunfighter Al J. Jennings, who had become an actor after his release from a long prison sentence for train robbery and was in the cast of one of her films. She found that she liked shooting and over the years had developed into an expert shot.
During the filming 'Audie Murphy' and a friend decided to go duck hunting on a nearby lake. The boat capsized and Murphy nearly drowned, but was saved by a female photographer who had been taking pictures nearby.
