Nan Goldin, photographer of Rob’s Dior Homme campaign talked a little about him in an interview with L’Express:
I loved taking pictures of women like Kate Moss naked on a horse, or Tilda Swinton, covered with hide. In front of them, I am in “caress” mode. I also enjoyed photographing Robert Pattinson for Dior, in a harsh light. He looks like a portrait of the painter Paul Cadmus exposed at the Brooklyn Museum in New York … Same brown hair, same blue eyes … Nothing about him rhymes with “pretty”.
