Movies, also known as films, are a type of visualcommunication which uses movingpictures and sound to tell stories or teach people something. People in every part of the world watch movies as a type of entertainment, a way to have fun. For some people, fun movies can mean movies that make them laugh, while for others it can mean movies that make them cry, or feel afraid.
Most movies are made so that they can be shown on big screens at movie theatres and at home. After movies are shown on movie screens for a period of weeks or months, they may be marketed through several other media. They are shown on pay television or cable television, and sold or rented on DVD disks or videocassette tapes, so that people can watch the movies at home. You can also download or stream movies. Older movies are shown on television broadcasting stations.
A movie camera or video camera takes pictures very quickly, usually at 24 or 25 pictures (frames) every second. When a movie projector, a computer, or a television shows the pictures at that rate, it looks like the things shown in the set of pictures are really moving. Sound is either recorded at the same time, or added later. The sounds in a movie usually include the sounds of people talking (which is called dialogue), music (which is called the "soundtrack"), and sound effects, the sounds of activities that are happening in the movie (such as doors opening or guns being fired). In the 20th century the camera used photographic film. The product is still often called a "film" even though there usually is no film.
A screenwriter writes a script, which is the story of the movie with dialogue and things that the actors will say and do. A producer hires people to work on the movie and gets all of the money that will be needed to pay for the actors and the equipment. Producers usually get the money by borrowing it from a bank or by getting investors to lend money to the movie production. Some producers work for a movie studio; other producers are independent (they do not work for a movie studio).
Actors and directors read scripts to find out what to say and what to do. The actors memorize the words from the script that they will say in the movie, and learn the actions that the script tells them to do. Then, the director tells the actors what to do and a cameraman takes motion pictures of them with a motion picture camera.
When filming has finished, an
editor puts the moving pictures together in a way that tells the whole story within a set amount of time. Audio engineers and sound engineers record music and singing and join it with the moving pictures. When the movie is done, many copies of the movie are made by movie labs and put onto film reels. Then the reels are sent to cinemas. An electric machine called a projector shines a very bright light through the film, and people sitting in a dark room see it on a big screen.
