Colin

About the Job

Colin is a thin man in his early 40s whose appearance feels slightly frozen in another era. Impeccably dressed in a cardigan with a neat 1950s hairstyle, he is polite, soft-spoken, and painfully awkward. Having spent most of his life in isolation, Colin longs for genuine human connection but lacks the emotional and social skills to build healthy relationships. Living under the influence of his older brother Richard, Colin has developed a deeply warped perception of love, care, and companionship. Fascinated by butterflies and the idea of preserving beauty forever, that same obsession extends to the women he kills, seeing them as something to possess and preserve rather than let go. What initially appears as kindness gradually reveals itself as manipulation, control, and ultimately horrifying violence. Colin is the film's primary antagonist—a serial killer whose polite demeanor masks a deeply disturbed and unpredictable mind. Despite committing unspeakable acts, he never believes himself to be evil. In his mind, he is rescuing, protecting, and preserving the things he loves. The role relies on subtlety rather than overt menace. Colin should make the audience feel sympathy, discomfort, and fear—sometimes within the same scene. The performance demands emotional restraint, vulnerability, quiet intensity, and the ability to shift naturally from gentle kindness to terrifying obsession without ever becoming theatrical or one-dimensional. As one of the film's two central characters, Colin carries much of the psychological tension and emotional complexity of the story.
