if you are doing stationary shots I suggest using Ultra 2, formally Serious Magic's program now owned by Adobe, included in the CS3 Bundle. It uses vector keying instead of chroma key so as long as it knows what the background looks like without the subject (flim a couple of seconds before actor is on cam) It will know the difference and you can key them out and apply the needed filters to give that preditor look
