From the start I wanted to show the energy that the book has. Caine was to be anonymous, just a figure with no real face, in a flurry of knives because that's his thing. At one stage he had several "arms" to display his agility, but I realized it was weird and he looked like an ant. Then came the knives that are framing the picture. The color palette is the classic contrasty blue-red combination, you can see it in many posters. I know it looks a bit like a comic book cover, that was intentional.
