Arthur Penn’s smouldering anti-western tells the story of Nicholson’s Montana horse-rustlers and the pursuit of them by Brando’s regulator Lee Clayton. The action is rationed into short, ferocious bursts and used as a counterpoint to the director’s paced dissection of power and politics on the anarchic frontier. Brando’s whispering Irish accent flirts with parody, but ultimately helps to lend Clayton a compelling air of psychotic menace.
