Themovies
In the 1920s American movies filled the cinema screens of the world. Most were made in Holly¬wood, a suburb of the city of Los Angeles in California. Hollywood's big attraction for film¬makers was its clean air and plentiful sunshine. The movies made there were bright and clear. By the 1920s it had become the film-making capital of the world.
Hollywood movies were made by large companies called studios. The men who ran these studios were businessmen and their main aim was to make as much money as possible.
