COMES A HORSEMAN opens. Dir. Alan J Pakula. Written by Dennis Lynton Clark. In 1940s Montana recent widow Jane Fonda and returned war vet James Caan unite to save their struggling ranches from falling into the hands of Jason Robards' rapacious land baron. Measured, meditative revisionist Western tilting at Fordian metaphors. Richard Farnsworth is Oscar nominated for best supporting actor.
