Photography: Grit - How'd they do that?

We learned about this gritty kind of photograph in the strobist class I took and I've been trying to find a good example of it. Enter Daniel Craig and this pic of him I discovered when I somehow ended up on The Girl with the Dragon Tattoo theatrical movie site. Ignore the texture overlay and just look at the man's face. The main light is coming from the left but there is either another light/reflector on the right side of his face. Beyond that, there is obvious post-editing and I wanted to know this part of the equation. So I emailed the photographer who taught the class and asked him. First, he's awesome and got back to me within an hour. Second, he explained a couple options that I could try, including one with a bare bulb (so I don't have to buy or rent any equipment). 

The technique is mostly used on men and often for athletes. The definition can be unkind to women. I found this pic in my library and decided to give Mike's post editing advice a try. 

Before

After

To really make the differences noticeable, I went to the max with the adjustments I made. From what I read, Lightroom is better able to perform this look because of the Clarity slider. Apple's Aperture Definition slider doesn't quite get there but I like the similarities and that I can get somewhat close in look and feel of the grit pic of Daniel Craig. The shadows on Lloyd's (Floyd's?) face are bigger because I don't have a reflector or second light on the right side, but it is similar. I decreased the saturation, upped the Shadows and Recovery and adjusted the Black Point. This is the extreme pic. When adjusted a second time, I'm quite happy with the result.

Final

All this to say that I have an idea for next year's preschool auction and it involves shooting the children with faux mustaches and oversized glasses and the like and editing them to look gritty. (Adjustments will be made, of course, so the girls in the class can feel pretty and princessy.)
