What I like about Layer Cake is its intelligent through-line. First of all, I think it's very close to the truth; I think this is what successful drug dealers are like. They don't drive around in flashy cars, they don't show off, they behave very quietly, they get on with their job and they earn lots of money. And it goes up and up and up and up the scale. Secondly - and selfishly - I like the moral aspect of the movie, which is that violence has consequences, and you feel emotionally involved with the violence.
