Why is The Killing considered an important film noir movie?

The Killing (1956) is regarded as an important late-period film noir primarily due to its innovative structural techniques. Specifically, the film is noted for its creative use of flashbacks and its nonlinear narrative, which distinguish it within the genre.1

While film noir is often characterized by elements such as cynical heroes, intricate plots, and stark lighting, The Killing—the first major film by director Stanley Kubrick—utilized these narrative complexities to elevate a taut caper story about a racetrack heist. By employing a nonlinear approach, Kubrick demonstrated the unique stylistic vision that would become a hallmark of his later career.231
