3．A film made for entertainment involves many people，sometimes hundred of people．
The producer is the overall manager of a film．He must decide whether a movie is made or not，raise money and hire the whole team of workers and actors．He also has to make plans to show and distribute the finished film in cinemas around the world．
Before a film is made，a story or an idea has to exist．A screenwriter writes the story，the words that the actors speak and instructions on how the action takes place．Sometimes it's based on a book，a play，a real event or an old movie，and sometimes on original ideas of the screenwriter．
If a producer wants to make a successful movie，he has to hire a good director．A famous director can get good actors to work with him．He is the most important person on the set and in charge of everything．He tells the actors what to do and decides how the scenes are filmed．
There're many other people whom a director must work with．The director of photograph is a person who knows everything about cameras，lenses and lighting and uses them to create the mood and atmosphere of scenes．Costume designers choose clothes and decide what the actors wear．
A successful movie often depends on how good the actors are．They are the only people the audience gets into contact with．They must not only learn the words that characters speak in the screenplay，but must also understand how to move and speak in a natural way．
Music is also an important part of most films．A composer writes music to create mood．Sound editors and producers put the fight music into the correct place of the film．
