Scarlett Johansson, Tom Ford, Keira Knightley But not every actress is willing to bare all for Leibovitz. According to Vanity Fair's guest art director Tom Ford, Rachel McAdams was scheduled to appear on the cover of the magazine's March 2006 Hollywood issue with Scarlett Johansson and Keira Knightley. Leibovitz was the photographer. At the last minute, McAdams backed out and the cover ran without her. Why the change of heart? The cover was scheduled to be a nude shoot. "She did want to do it, and then when she was on the set I think she felt uncomfortable, and I didn't want to make anybody feel uncomfortable," Ford told ABCs "Good Morning America." In the end, a clothed Ford appeared with the nude actresses on the cover.
