"The Unforgiven" was the last film shot during Hecht-Hill-Lancaster's status as a working and successful unit and was released in the spring of 1960, by which time the company had dissolved (prior to their limited comeback a year later). The western, filmed using the Panavision Technicolor widescreen lenses on location in Durango, Mexico, dealt with racial intolerance towards Native Americans. The film was filled with star names including director John Huston, former blacklisted writer Ben Maddow (who adapted the screenplay from a novel by Alan Le May), and actors Lancaster, John Saxon, Charles Bickford, Audie Murphy (who replaced Tony Curtis after he dropped out), Albert Salmi and Joseph Wiseman and actresses Audrey Hepburn and Lillian Gish. Production was delayed for months when Hepburn fell off a horse and injured her back.
