Clint Eastwood was originally cast for Jeremiah Johnson, which would have given the movie much more authenticity as the real John Johnson known as “The Crow Killer” was a mountain man of mountain men. Many legends grew up around him which you can easily order and read in the book “Crow Killer.” Jeremiah Jonson is based on a semi true story. On the wagon trains coming across the plains, people would threaten their kids that they will send liver-eating Johnson after them if they do not behave. He killed Crow Indians by the dozens and ate their livers aftewards. I can see Clint doing this, but not Bobby.
