As faithful readers will no doubt have guessed, I have not seen Don Siegel's 1971 version of the same novel.
Even so, considering the context, the director and the male lead (Clint Eastwood), I'm going to go out on a limb and assume that the two films are fundamentally different.
Despite the civil war setting, Coppola's movie feels profoundly modern.
Attention lies on the women, Farrell's wounded soldier serves mostly as a foil, triggering and funnelling their actions and feelings (multilayered, confuse and sometimes contradictory, as feelings tend to be).
Plus : Beautiful imagery and the perfect, 90-minute format. A treat!
