Knives Out

Rian Johnson’s Knives Out presents itself as a clever murder mystery, a homage to Agatha Christie with modern flair. Yet beneath the polished veneer of a whodunit lies a far more subversive work: a critique of class hierarchy, inherited wealth, and the illusions that sustain capitalist power. From a Marxist perspective, the film is not simply about solving a crime—it is about unmasking the parasitic decadence of a ruling class in decay.

The Thrombey family, with their sprawling estate and dynastic self-importance, represent the bourgeoisie in its most naked form. Each member believes themselves entitled to the fruits of the patriarch’s labor, not through their own effort, but by virtue of bloodline and inheritance. Their contempt for Marta, the immigrant caretaker, is cloaked in feigned benevolence—“she’s like family,” they insist, even as they forget her country of origin and plot to expel her once she becomes an obstacle to their wealth. Their hypocrisy mirrors how capitalists rely on labor while simultaneously demeaning it, insisting on loyalty while preparing betrayal.

Marta, by contrast, embodies the proletariat: diligent, kind, and indispensable, yet positioned socially as invisible. Her moral compass—symbolized in her inability to lie without vomiting—contrasts starkly with the Thrombeys’ web of deceit. It is no accident that the truth emerges not through their self-policing but through her perseverance and the intervention of Benoit Blanc, the detective who plays the role of historical materialist, unearthing the contradictions at the heart of the estate.

The film’s resolution—Marta on the balcony, coffee cup in hand, looking down upon the disinherited Thrombeys—constitutes more than poetic justice. It is a cinematic image of revolution, the servant elevated above the masters, the world turned upside down. The estate, once a fortress of bourgeois security, becomes a stage upon which the capitalist class is stripped bare, revealed as incompetent, greedy, and fragile.

Knives Out succeeds not only as an entertaining mystery but as an allegory of capital’s rot. It exposes the myth of merit within wealth, the corrosive power of entitlement, and the inevitability of collapse when the ruling class mistakes inheritance for virtue. In Johnson’s hands, the knife does not merely cut—it dissects the social body, laying bare the contradictions that Marx identified: that those who own, rule, and exploit are ultimately dependent on those they despise.
