Why Opening Sequences are Important

Opening sequences create an important part of the film. They introduce some of the main characters that will have an effect that carrys on throughout the film. It also presents the industries that have had an input to the film. They make sure the audience knows that the rest of the film is about this and the questions they ask will be from this early clip. This will answer no question only open the audiences minds as to what is to come in the rest of the film.
It allows the industries to gain credit for the production that they gave created. If the opening sequence was not included in the film, the whole film would not make sense and would be a complete waste of time, as you would not be introduced to the characters and wouldnt know who the main actors were either.
