New Delhi, March 3 (ANI): Dakota Johnson's pubic hair shown in the erotic movie ' Fifty Shades of Grey ' was not real, it has been revealed. Seamus McGarvey, 'Fifty Shades' cinematographer, revealed during a panel discussion that Johnson had kind of a patch that went over her pubic area, and right round her whole body. Seamus continued that they were in the curious situation, in post-production, of adding pubic hair and he wouldn't say that it was one of the highlights of his career, but it certainly was one of the most surreal scenarios. He also revealed that they also cast a butt double for Dakota for the scene where Jamie Dornan, who plays Christian Grey spanks her a number of times with a belt, leaving her in tears.
