Do you still remember the stories you have heard when you were a child?If yes then remember how you used to get involved in the stories told by your grandma or mom.The very reason of telling a story is to communicate a specific message or moral.Remember how the person telling a story expresses the different characters and emotions by acting differently or changing the
facial expressions or tones.We definitely used to enjoy that and get involved in the story and start picturising ourselves in place of some character in the story.We start picturising more and more in our mind as we get involved more into the story.That leads us to believe more and more in the fiction.The same concept applies to the films or movies.The people making the film are trying to express or let's say communicate a specific message to the audience.Ofcourse the medium is rich and it becomes a bit easier then the grandma's process but the essence remains the same,to tell a story in the best possible way.
