Film noir (/nwɑːr/; French: [film nwaʁ]) is a cinematic term used primarily to describe stylish Hollywood crime dramas, particularly those that emphasize cynical attitudes and sexual motivations. Hollywood's classical film noir period is generally regarded as extending from the early 1940s to the late 1950s. Film noir of this era is associated with a low-key, black-and-white visual style that has roots in German Expressionist cinematography. Many of the prototypical stories and much of the attitude of classic noir derive from the hardboiled school of crime fiction that emerged in the United States during the Great Depression.

The term film noir, French for "black film" (literal) or "dark film" (closer meaning),[1] was first applied to Hollywood films by French critic Nino Frank in 1946, but was unrecognized by most American film industry professionals of that era.[2] Cinema historians and critics defined the category retrospectively. Before the notion was widely adopted in the 1970s, many of the classic film noir[a] were referred to as "melodramas". Whether film noir qualifies as a distinct genre is a matter of ongoing debate among scholars.

Film noir encompasses a range of plots: the central figure may be a private investigator (The Big Sleep), a plainclothes policeman (The Big Heat), an aging boxer (The Set-Up), a hapless grifter (Night and the City), a law-abiding citizen lured into a life of crime (Gun Crazy), or simply a victim of circumstance (D.O.A.). Although film noir was originally associated with American productions, the term has been used to describe films from around the world. Many films released from the 1960s onward share attributes with film noirs of the classical period, and often treat its conventions self-referentially. Some refer to such latter-day works as neo-noir. The clichés of film noir have inspired parody since the mid-1940s.

The primary literary influence on film noir was the hardboiled school of American detective and crime fiction, led in its early years by such writers as Dashiell Hammett (whose first novel, Red Harvest, was published in 1929) and James M. Cain (whose The Postman Always Rings Twice appeared five years later), and popularized in pulp magazines such as Black Mask. The classic film noirs The Maltese Falcon (1941) and The Glass Key (1942) were based on novels by Hammett; Cain's novels provided the basis for Double Indemnity (1944), Mildred Pierce (1945), The Postman Always Rings Twice (1946), and Slightly Scarlet (1956; adapted from Love's Lovely Counterfeit). A decade before the classic era, a story by Hammett was the source for the gangster melodrama City Streets (1931), directed by Rouben Mamoulian and photographed by Lee Garmes, who worked regularly with Sternberg. Released the month before Lang's M, City Streets has a claim to being the first major film noir; both its style and story had many noir characteristics.[35]

Wikipedia: PULP MAGAZINES
Pulp magazines (often referred to as "the pulps") were inexpensive fiction magazines that were published from 1896 to the 1950s. The term pulp derives from the cheap wood pulp paper on which the magazines were printed. In contrast, magazines printed on higher-quality paper were called "glossies" or "slicks". The typical pulp magazine had 128 pages; it was 7 inches (18 cm) wide by 10 inches (25 cm) high, and 0.5 inches (1.3 cm) thick, with ragged, untrimmed edges.

The pulps gave rise to the term pulp fiction in reference to run-of-the-mill, low-quality literature. Pulps were the successors to the penny dreadfuls, dime novels, and short-fiction magazines of the 19th century. Although many respected writers wrote for pulps, the magazines were best known for their lurid, exploitative, and sensational subject matter. Modern superhero comic books are sometimes considered descendants of "hero pulps"; pulp magazines often featured illustrated novel-length stories of heroic characters, such as Flash Gordon, The Shadow, Doc Savage, and The Phantom Detective.
