I did a lot of testing before I started to make this movie with skins and how they would work against low level backdrop as this is where most of the action would be taking place and settled on thoes too and also because I wanted to give the impression that they were taking it in turns to have a pop at the nme I wanted them to be visually very different and easily distinguishable, this is above all else a visual movie, you will find little historical correctness here.
