How does my peice represent social groups?

My piece does challenge some representations of social groups as we have cast an upper class man as a murderer, this challenges the conventions of upper class citizens, as they are usually very proper in the way they do things, as such the fact that he is a murderer comes as a shock to the viewer. We have kept to some representations of some social groups, for instance our victim is lower in the economical chain than the murderer, and this shows that the rich have more power over the middle and lower classes. It also shows certain callousness from our murderer as he feels he can murder a lower class woman and get away with it, instead it will haunt him.

This is another convention we have broken, as in thrillers the convention is to have a cold hearted killer that does not care who they hurt as long as they get what they want (shown in films such as the Hannibal series) we have created a killer with a conscience, this challenges the conventions of a thriller, and, the representations of killers. We have done this on purpose to make our film stand out from the crowd
