The 1992 landmark movie by Clint Eastwood, “Unforgiven,” follows William Munny (Eastwood), a ruthless killer now transformed into a family man, in what could be seen as an epilogue to the tale of the gunslinging cowboy Eastwood portrayed in his younger days. David Peoples, the original author of the 1976 story titled “The William Munny Killings,” shared the movie’s original ending.
