1978 film by Alan J. Pakula
Comes a Horseman is a 1978 American Western drama film starring Jane Fonda, James Caan, Jason Robards, and Richard Farnsworth, directed by Alan J. Pakula.
Set in the American West of the 1940s but not a typical Western, it tells the story of two ranchers, Frank "Buck" Athearn (Caan) and Ella Conners (Fonda), whose small operation is threatened both by economic hardship and the expansionist dreams of local land baron Jacob "J.W." Ewing (Robards).
