The world capital of filmed entertainment Los Angeles has been a lot of things over the past 100 years. First, it was a little city with orange forest and great weather. But, one day in 1908 a group of people from Chicago came to Los Angeles to shoot (make) a film. Since that day a lot of directors, producers, actors and thousands of other workers have been coming to Los Angeles. In 1911 the first studio appeared in Hollywood (a part of Los Angeles).

In the 1920s Hollywood made 80% of the world’s films. Silent and black-and-white films of those early years starring Mary Pickford* and Charlie Chaplin* were forced out by sound films in the middle of the 1920s. Full – length films came up to take place of short films. And the first coloured film, “Gone With the Wind” was shot in 1939. This film brought a great success to Vivien Leigh* and Clark Gable* who starred in the film. The number of the studios grew very quickly. They combined in large corporations and now the biggest film companies are MGM*, Paramount*, 20th Century Fox*, Columbia Pictures*, Warner Bros*, and Universal*.

The first genres of American films were melodrama, western and comedy, later appeared adventure and historical films. But now the range of genres is much richer. Hollywood got the name of the factory of dreams. It is associated with paradise of sun and palm trees. But it is only a facade for a darker truth.
