Henry Fonda as a psychopathic bad guy.. No way, you say?... "Once Upon a Time in the West" was Sergio Leone's greatest Western, although Clint Eastwood's three films remain among my favorites. Leone had hoped to have Eastwood in this film as "Harmonica", but they were unable to work things out. As it is, I think having Charles Bronson in the role was more effective. It was central to Eastwood's persona in those three films that he be both a man with no name and with no past, but Bronson's character of Harmonica was entirely driven by the past and his need for revenge. He was brilliant, and his tiny, piercing blue eyes lent an eerie intensity to many of his screen moments. The casting of the equally blue-eyed Henry Fonda as a sadistic villain was a stroke of genius, and he managed to produce one of his most memorable roles. This was an incredible movie, and by far, one of the most thoughtful, unique Westerns ever made. The ending is the finest of his many westerns, as well as one of the most surprising. It easily goes on any list of the greatest westerns in the history of film.
