The latest film to shed light on Hemingway's life is the HBO drama “Hemingway & Gellhorn,” a picture about his relationship with his third wife, Martha Gellhorn. Although Hemingway is the best-known half of the power couple, Gellhorn is noteworthy in her own right, having established a career as one of the finest war correspondents of the 20^th century. The film begins and ends with an aging Gellhorn (portrayed beautifully by Nicole Kidman) recalling her past.
