In the book, some of the instances that occur in Animal Farms exposition play important roles later on in the book. At the start of the book you are introduced to a flurry of thoughts and ideas that are very instrumental throughout the remainder of the book. The exposition begins with Old Major, telling the animals of a dream he has in which all animals are free from the oppressive human regime and equal amongst each other. He is a prophet, planting the seeds of rebellion in the minds of the animals that have gathered around to listen to what he has to say. It is this powerful speech that is the catalyst for the animal revolution which occurs not too long after. In the exposition, they also sing the song "Beasts of England", which becomes their national anthem and it is sung throughout the book, playing an important role later on in the book. There are many other things which occur in the exposition that become important symbolisms as the book progresses. The exposition in Animal Farm the movie is the same as the books in terms of plot, but it is different in many other ways. One must remember that the movie is merely and adaptation of the book into film, so almost all the events that take place in the book will take place in the movie. This is the case with the exposition, yet many other key differences can be seen between the two. Firstly, exposition seemed to rush through some of the events which are very important later on in the book. For example, in the books exposition, Orwell describes many of the animals that are important to the book. In the movie's exposition, very little time is spent on developing the characters of the important animals. Also, the song "Beasts of England" is not sung in the exposition, unlike the book. Reiterating the statement in the last paragraph, this song plays a very pivotal role later on in the book. While reading the book, one soon begins to fell sympathetic towards the animals on Animal Farm.
