"We can kill 'em but we can't fuck 'em. It says so in the Bible."
--Wardaddy (Brad Pitt), on military relations with indigenous female personnel, in Fury, perhaps the finest war film ever made. It's a kind of Saving Private Ryan, without the gentleness.
The quote is illustrative of Fury's repeated interplay between "God's grace" (which Pitt utters early in the film from the bleak, monochromatic innards of an American tank, as the camera pans an even bleaker, near-apocalyptic European battlefield that's reminiscent of the previous "Great War") and the brutality of man. The latter, as a cinematic theme, is enough of a Hollywood convention that a truly fine war film would dispense with it as a centrality; hence the indispensability of Fury's theological angle, which can be read by religionist, atheist or agnostic with equal knowingness.
This film--a brilliant, respectful piece of work--leaves the knowingness up to you.
And you should stick around for the credits. I'll say no more, other than that the credits complete the film in an essential way.
