sentences:  The word noir, from film noir, is the French term (literally black film) for American black-and-white films of the 1940s and 1950s, which always seemed to be set at night in an urban landscape, with a suitably dark subject-matter, although the treatment is often sexy and glamorous as well as stylised and violent.Being often typified by crime thrillers with a private detective hero and a succession of attractive, deadly heroines, the genre informed a slew of crime novels, Raymond Chandler's "The Big Sleep" and "Farewell, My Lovely" being notable examples; whence, detective noir.From this derive various related and subverted terms, such as neo-noir (resurgence of the form in 1960s and 1970s America); the Cold War noir (exploiting the tension and paranoia of the nuclear age); blaxploitation films, which some called black noir; Nordic noir, set in the stark landscape and apparently bland social environment of the Scandinavian countries, yet revealing a dark legacy of cruel misogyny, brutal sexual repression, and murder.
