The Great Train Robbery was one of the first films to use a narrative story format, special effects, and color.
The famous film Citizen Kane by Orson Welles was heavily based on the life of newspaper tycoon William Randolph Hearst. Hearst tried to keep the film from being distributed.
The "post-Will Hayes" ratings are NC-17 (cannot be viewed by anyone under 17) and R (cannot be viewed by anyone under 17 unless accompanied by an adult).
The movie industry has been largely self-censored. The Hayes censorship board was funded by the Motion Picture Producers Association. The MPAA was formed by the movie industry to prevent government regulation of cinema. This group sets the standards for film.
The independent short film 405, by Bruce Branit and Jeremy Hunt, gained notoriety for its high quality special effects created with advanced computer software.
