Everyone knows McCabe and Mrs. Miller is mostly a shadowy, brownish-amber, earthy-looking thang…wood grain, candlelight, gaslamps, misty rain, cloudy skies, muddy streets, fallen snow, a climactic blizzard. Except, that is, in the mind of the sociopath who designed this “happy” poster. The idea was to suggest to would-be viewers that Robert Altman’s 1971 western was an upbeat package with a sunny, robust attitude…pink horse, pink buildings, burnt-orange Julie Christie, green prostitutes, yellow-tint Warren Beatty.
