The wilderness is the location chosen by the titular character to recover from what we would call PTSD nowadays as Robert Redford has had a bad war in Mexico and needs time away from everything. He lives in the Rocky Mountains, keeping himself in food by trapping and enduring a horrendous winter, resorting to fishing by hand from mountain streams. He finds a rifle in a dead man’s hands, meets Bear Claw (Will Geer) who mentors him, and has repeated encounters with Paints-His Shirt-Red (Joaquin Martinez) from the Crow tribe. He takes in a boy he names Caleb (Josh Albee) whose mother has gone mad, then rescues Gue (Stefan Gierasch) who’s buried up to his neck in sand by the Blackfeet, then he marries into the Flatheads to save his own. He’s pressured to lead US troops to a wagon train of settlers through burial ground and is seen: he returns to find his squaw and Caleb murdered and he takes revenge… The biography of Liver-Eating Johnson and a book called Mountain Man were adapted by John Milius in a project originally intended for Sam Peckinpah with Lee Marvin replaced by Clint Eastwood. Eastwood and Peckinpah did not get along, so it was acquired for Redford, who persuaded Sydney Pollack to come on board to direct – they had worked together well on This Property Is Condemned. Pollack was a meddler with writers; Edward Anhalt and David Rayfiel did rewrites but Milius was brought back, repeatedly, to do the dialogue, for which he had such an uncanny ear. If you want to know how Milius got his reputation, watch this. The budget was so constrained that Pollack mortgaged his home to get through production, an arduous seven-month shoot in Utah, Redford’s adopted home. Weather conditions meant more than one take was rarely possible. The changing seasons are beautifully captured by Duke Callaghan, in this splendidly judged, humane, funny, touching piece of work. Redford turns in a very well honed performance and the ensemble are brilliant. Quite the best wilderness film you’ll see, probably, with a marvellous soundtrack composed by actors Tim McIntire and John Rubinstein.
