First of all, you will need someone with a good working knowledge of lighting because there are at least three lights on the subject:
1. Forehead illuminated by a well collimated, narrow beam (snoot or Fresnel - a gridded softbox probably won't be good enough) light that is to the viewer's left and slightly in back of the subject.
2. Near shoulder illuminated by another narrow beam light that is almost directly above the camera.
3. The back of the subject's head and his back are illuminated by yet another narrow beam light that is to the viewer's right and also slightly in back of the subject.
All three of the lights are probably gelled to get close to the orange look. You can't get quite the same color look using only the color balance sliders in ACR, even if you shoot RAW.
You will also need a camera with a relatively long, wide aperture lens - almost certainly over 100 mm (35 mm equivalent focal length) and probably f/2.8 or faster to get nice bokeh for the background.
From there, you will need to deal with makeup (eg, getting the glossy / reflective skin areas right), hair styling, fake beads of sweat, what is almost certainly a well painted, fake studio backdrop (well lit, obviously).
And, after all of the above are in place, then you can turn to the post-processing techniques, which, as far as I can tell, are with one exception, nothing terribly special -- maybe just a bit of tweaking to get the colors exactly right for the plugin I'll mention in the next post, and an application of "curves" to gently crush the blacks and deep shadows in various areas of the image.
If you try to duplicate this look using only PS, but without the proper lighting, lens, backdrop, and makeup, IMHO, you will be very disappointed.
HTH,
