It can often be hard to turn a book into a movie. The reader usually feels that the director has done the author some injustice by not including every little detail from the book or by adding things of their own. In the case of Persepolis, because it began as a comic book and already came with visual materials of it’s own the creator of the movie had the interesting job of bringing such images to life. Although the director did keep the general look and feel of the pictures the same, one of the interesting differences is the use of shading in the background. In the movie the background is often shaded in a way that adds a gradient of light, unlike the strictly black and white shapes used in the book. This difference allows for a range of light to be used to portray different emotions. Generally light was used to portray happiness and darker surroundings were used to portray a sadder or madder emotion. This use of light wasn’t limited to exactly such uses but when it did stray it was for a specific purpose such as having a specific character be lighter and this the background was required to be dark. It also allows for a more three dimensional look to take place as buildings fade into the background, and when things are moved closer they can have more light upon them. Although subtle this difference plays an important role in distinguishing the film from the book and adds to the power of the movie. This is not to say that the movie was more powerful. If anything the standing images were more moving, but the shading did help the movie to win over more support in that field. Shading was important and should not be overlooked.
