The Killing of a Sacred Deer (2017) is an unsettling psychological thriller that blends slow-burning tension with haunting emotional depth. Directed by Yorgos Lanthimos, the film follows Steven, a respected surgeon whose seemingly perfect life collapses after a teenage boy he mentors begins to reveal a darker, more manipulative side.

The story unfolds with a chilling sense of control, showing how Steven’s confidence and authority slowly crumble. What begins as a benevolent connection between doctor and teenager quickly spirals into something disturbing, forcing Steven to confront the fragility of his own world. The film builds its suspense not through loud scares, but through quiet, precise moments that make viewers increasingly uneasy.

As the boy’s behavior becomes more sinister, Steven faces an impossible decision—one that tests his morality, his family, and his understanding of justice. Every choice feels heavier than the last, pushing him toward a sacrifice that no parent should ever have to consider. This moral dilemma becomes the emotional backbone of the film, turning a surreal premise into something deeply human and terrifying.

The Killing of a Sacred Deer stands out for its cold, dreamlike style, its sharp performances, and its fearless exploration of guilt, responsibility, and fate. Colin Farrell delivers a gripping performance as Steven, while Barry Keoghan’s unsettling portrayal of the teenage boy creates a tension that lingers long after the film ends.
