Place the actor a few feet away from a white wall. Light the wall and set your exposure. Then lock the setting and place the actor in the shot. You can use a small light placed above and behind the actor - aimed at the back of his head - to make the silhouette a bit more pronounced.

If it's not exactly the way you want it change the exposure - open or close the aperture until you get the desired effect. Sometimes even a little light on the face will work - still keeping the subject in darkness, but adding a little detail.

Thank you for taking the time to respond. I knew some one would have some specifics.

Thanks again.

Personally I would have a little light coming in real sharp from the side and a little to the back, which would light just the tip of the nose and the highlights, like maybe the chin and the eyebrows. If it's a dim enough light and you get your exposure right, I think it would be very cool.
