McCabe & Mrs Miller

Robert Altman - 1971
Altman makes his assault on the western genre by employing snow, a lot of bodily functions, and a weak, idiotic, alcholic lead. Shot with that low dialgoue mix, complicated sound (I love the raindrops), and wide takes that take in the dingy environment, he also isn't averse to cutting about into his closer shots.
As the stagger around, covered in blood, qhile the rest of the world quite literally burns, they are seen as rather pathetic. The genre won't allow this idea fully, but it is clearly there from McCabe's alchoholism, his lack of ability to count. Even Julie Christie's opium habit is a bit embarrasing. I don't think Altman exactly escapes genres, he can't quite explode them (see Althusser; every ideology is true in itself), but he makes it impossible for others to move around in it, which is perhaps the extent of the possible battle.
