An incredible portrait photographer. I most interested in the lighting set up despite the actual incredible content that is George Clooney. Assuming that there was very little post production. I would have guessed that there were two strip boxes either side of the lens at around 60 degrees from the model. the strip boxes would have been close, allowing for such a soft texture, although it was far away enough for the entire box to be reflected in the eyes. these soft light would not have been used as a flash but as a modelling light hence the shallow depth of field. The back however is a strobe: reflector with a small angled spot grid giving the gradient.
