The Killing of a Sacred Deer is a 2017 psychological horror film directed by Yorgos Lanthimos, who co-wrote the screenplay with Efthimis Filippou. This unsettling and thought-provoking movie delves deep into themes of guilt, justice, and retribution. With an eerie atmosphere and unsettling narrative, the film keeps viewers on edge, making them question the nature of morality and the consequences of one’s actions.

The story centers around Steven Murphy (Colin Farrell), a successful heart surgeon, and his seemingly perfect family. Steven’s life begins to unravel when he befriends a teenage boy named Martin (Barry Keoghan), who has a mysterious and sinister connection to him. As the plot progresses, Martin’s intentions become clearer, and Steven finds himself caught in a nightmarish situation where the lives of his loved ones are at stake. Martin demands a gruesome payment for a past wrong, forcing Steven to make an impossible choice.

The film’s slow-burn tension is driven by Lanthimos’s signature deadpan style, where the characters’ unnatural, emotionless dialogue and behaviors create a sense of unease. The performances of Colin Farrell and Nicole Kidman, who plays Steven’s wife, Anna, are captivating. They portray a couple who must face a moral dilemma that shakes the very foundations of their family life. The film’s atmosphere is further heightened by the haunting soundtrack and minimalist production design, adding to the surreal experience.

One of the film’s central themes is the exploration of guilt and punishment. Martin’s actions suggest a form of divine or cosmic retribution, as if he is an instrument of fate, demanding justice for a past wrong. The audience is left to question the nature of justice itself: Is it a personal responsibility, or does it transcend human understanding? The title, The Killing of a Sacred Deer, refers to the Greek myth of Iphigenia, where a sacrifice is demanded for the greater good, an idea that echoes throughout the film.

The use of ambiguity in the plot is one of the most striking aspects of the film. Lanthimos never fully explains Martin’s motivations or the origin of his mysterious powers, leaving the audience to interpret the story in their own way. This lack of resolution challenges traditional storytelling and invites viewers to confront their own interpretations of morality, fate, and the consequences of one’s actions.

In conclusion, The Killing of a Sacred Deer is a haunting and intellectually stimulating film that explores complex themes through its chilling narrative and unique style. Yorgos Lanthimos masterfully weaves a story of guilt, punishment, and retribution, creating a cinematic experience that is both disturbing and thought-provoking. It is a film that lingers long after the credits roll, forcing viewers to confront uncomfortable questions about justice and the human condition.
