There may be no other gangster film in existence that walks the tightrope Miller’s Crossing walks. On the one hand, the third film from the Coen Brothers is of a piece with the 1930s gangster flicks that influenced it, full of colorful criminals and double-crosses and rat-a-tat action. The dialogue is straight from Dashiell Hammett and the production design is straight from the pre-Code era, à la Scarface and Little Caesar. The gangster subgenre and critical thinking on the subgenre are historically grounded in realism, unlike the mythic and symbolic trappings of the film Western, and Miller’s Crossing honors that in its gritty, ruminative approach to a complex plot. It is, in short, a quintessential gangster film.
On the other hand, stuff like this happens:

The pure gangster film we’ve described so far is constantly in sharp discordance with the Miller’s Crossing that knows it’s a gangster film. Self-awareness is not a traditional quality of the gangster picture. We’re supposed to be shocked when characters get riddled with bullets, not laugh at the absurdity of the manner of their demise (see above). Big hulking goons are supposed to be aces in fistfights, not whimper when they get bonked on the nose. And we’re not supposed to be expending energy reading into tophat dream symbolism during a traditional crime flick, right? In short, this is anything but a quintessential gangster film.
