A film genre is a rough categorization of films into genres, which describe the typical subject matter—what the film is about: Western films are about the American West, love stories are about love, and so on. This is distinct from film styles, which describe filmic conventions which can be applied to any genre (see below). Of course, the more that genres are defined, the more likely that a filmmaker will try to combine, transcend and evade categories, so not every film can be neatly labeled.
A film style is a recognizable group of conventions used by filmmakers to add visual appeal, meaning, or depth to their work. It can encompass every aspect of film: dialogue, cinematography, attitude (i.e., seriousness or lack thereof).
Film style is distinct from film genre, which defines what a film is about. Although some styles are strongly associated with certain genres, a style can be applied to any genre -- Barbarella is a surrealistic science fiction film, for example.
Obviously each filmmaker develops their own film style, but certain styles that transcend individuals include:
The 1950s was the most represented decade on the list, with 20 films.
And 70 of the films on the list were from 1950 and after.
The Godfather, Part II (1974) (at #32) was the only sequel represented on the list, although it could be argued that The Silence of the Lambs (1991) (at #65) was a sequel to Manhunter (1986).
By the early 1920s, most films came with a prepared list of sheet music for this purposes, with complete film scores being composed for major productions.
The rise of European cinema was interrupted by the breakout of World War I while the film industry in United States flourished with the rise of Hollywood.
Filmmaking takes place all over the world using different technologies, styles of acting and genre, and is produced in a variety of economic contexts that range from state-sponsored documentary in China to profit-oriented movie making within the American studio system.
