Film is a term that encompasses individual motion pictures, the field of film as an art form, and the motion picture industry. Films are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects. Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment, and a powerful method for educating -or indoctrinating- citizens. The visual elements of cinema give motion pictures a universal power of communication; some movies have become popular worldwide attractions, by using dubbing or subtitles that translate the

.In the United States today, much of the film industry is centered around Hollywood. Other regional centers exist in many parts of the world, such as Mumbai-centered Bollywood, the Indian film industry's Hindi cinema which produces the largest number of films in the world. Though the expense involved in making movies has led cinema production to concentrate under the auspices of movie studios, recent advances in affordable film making equipment have allowed independent film productions to flourish.
Profit is a key force in the industry, due to the costly and risky nature of filmmaking; many films have large cost overruns, a notorious example being Kevin Costner's Waterworld. Yet many filmmakers strive to create works of lasting social significance. The Academy Awards (also known as "the Oscars") are the most prominent film awards in the United States, providing recognition each year to films, ostensibly based on their artistic merits. There is also a large industry for educational and instructional films made in lieu of or in addition to lectures and texts.
The nature of the film determines the size and type of crew required during filmmaking. Many Hollywood adventure films need computer generated imagery (CGI), created by dozens of 3D modellers, animators, rotoscopers and compositors. However, a low-budget, independent film may be made with a skeleton crew, often paid very little. Also, an open source film may be produced through open, collaborative processes. 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.
In the 1990s and 2000s, the development of digital DVD players, home theater amplification systems with surround sound and subwoofers, and large LCD or plasma screens enabled people to select and view films at home with greatly improved audio and visual reproduction. These new technologies provided audio and visual that in the past, only local cinemas had been able to provide: a large, clear widescreen presentation of a film with a full-range, high-quality multi-speaker sound system. Once again, industry analysts predicted the demise of the local cinema. Local cinemas will be changing in the 2000s and moving towards digital screens, a new approach which will allow for easier, quicker distribution of films (via satellite or hard disks), a development which may give local theaters a reprieve from their predicted demise.
