Since 19 10' s, Hollywood has started to shoot science fiction films, and directors and actors of past dynasties have presented many excellent science fiction films to the audience. More than half of the world's science fiction movies are made in the United States.

Throughout the history of American science fiction movies, the development of American science fiction movies can be divided into several periods: germination, growth, maturity, prosperity and balance.

Characteristics of early American science fiction movies;

The early 20th century to the 1920s was the embryonic period of American science fiction movies. The rise of science fiction movies has made American filmmakers feel the huge commercial profits in science fiction movies and began to produce and distribute science fiction movies. 19 10 American director Thayer Dowley filmed Frankenstein, a silent film based on mary shelley's novel of the same name.

Although this movie is only 16 minutes, it is the origin of American science fiction movies and has a great influence on the future development of American science fiction movies. Since then, Hollywood has successively produced Wan Li under the Sea directed by Stuart Barton (Two Wan Li under the Sea, 19 16) and The Lost World directed by Harry Huo Yite (1925) and Mysterious Island (directed by Lucien Hubbard).

The sci-fi films of this period are mainly B-rated films with low production cost, with simple stories and single characters. Most films are silent films, and most sci-fi shots are shot with multiple exposures. There are no real special effects, and some are full of horror.
