(analysis) The use of black and white

When the group of lads are brought into the film I use black and white in all the scenes they are in. This is to create a sense of suspicion around the group and makes the audience question why they are portrayed in this way. The use of black and white also connotes good and bad. There is a conflict between the fact that the lads are just trying to have a good time but they are also doing something extremely dangerous by drink driving.
