Rench LiteratureHow is the movie Vipere au Poing different or representative of the novel Vipere au Poing?

This essay has to be written in french, therefore the title is actually En quoi le film est il different ou representatif de loeuvre litteraire Vipere Au Poing?

The comparison should entail character comparisons, ie their physical details, feelings, way they are portrayed, their relationships; the time and place, ie. the house, the environment around it, clothes, the time period, their customs; the third and final part should entail what has been lost by translating the book into a movie.

Throughout it should also be discussed why some elements appeared in one and not the other (meaning in the movie and not the book, or vice versa).

If it is not possible to do it in french, then in english will suffice.
