Reading, many different elements go into making a film. The lecture below was given by a film critic at the school film festival. Before you read the lecture transcript, think about the following questions. What elements of a film can you think of? Which element do you think is the most important in making a successful . film behind the scenes? Hello, everyone. Let me start by asking you a question. What's the first thing you notice about a film, the acting, the music, maybe the amazing sets? Whatever your answer is, there's always a lot more to IT than first meets the eye. Actually, the film you see on the screen is the product of a huge amount of hard work, most of which takes place behind the scenes. Today, i'll give you a brief introduction to some aspects of filmmaking you might not be familiar with. To begin with, i'd like to draw your attention to an important factor of a film sound effects. These are athon added after a scene has been shot and might not be made in the way you would expect. For example, in jurassic park, the sounds of different animals, including a baby elephant and a tiger, were mixed by a computer to make a dinosaur roar. The sound of the doors opening in the star track films was made simply by pulling a sheet of paper out of an envelope. Another aspect I attach great importance to his visual special effects. CGI has been frequently used in filmmaking as a special effects technology generally, since requiring CGI are filmed in front of a Green screen in the studio. As Green doesn't match any natural hair or skin color, actors can be easily separated from the background. This enabled C, G, I effects to be added later. The credit t scenes in the Harry potter films were made in this way, with the actors jumping up and down in front of a Green screen. However, the ative computers isn't always preferred. Peter Jackson, director of the lord of the rings films, took a creative approach. He used clever camera angles to make characters seen bigger or smaller than they really were. Props also contribute to a film success. To make a film look real, great effort must sometimes be made to research, find in, build objects. Director James Cameron spent six months looking at and revising plans of the titanic in order to build a full sized model for his nineteen ninety seven film, he talked to historians to ensure that the details were correct, and even went down to the bottom of the atlantic ocean to see what was left of the ship for himself. IT took five hundred workers, one hundred days to build the fine model. Not to mention the thousands of props inside my lecture today may not be able to do justice to all the work people have done behind the scenes. Just as the poor passengers on the real titanic saw the tip of the iceberg, what we see on the cinema screen is just the tip of the huge iceberg filmmaking. Hopefully, next time you go to the cinema, you'll spare a thought for all those talented people behind the scenes. They have worked for months and even years so that you can have two hours of enjoyment.
