1) The lighting. For this picture, I back-lit Koji from both sides, then bounced light back into his face, holding a Photoflex LiteDisc next to the camera, with the gold side towards his face. This provided just enough light - too much would have ruined the back-lighting effect.
2) The knife. We needed something sinister-looking, and this knife - all steel, no wooden or plastic handle - fit the bill nicely.
3) The blood. My initial attempts at making blood were somewhat disappointing, so Koji mixed up a concoction of syrup, corn starch, red food coloring, coffee grounds, and soya sauce.
4) The tie. We initially looked at bow-ties, but settled on a conservative blue tie, to contrast with the scarier elements of the photo.
