“At first, I rehearsed with wigs and fake facial hair. But I could never be satisfied with fake props, and so I ultimately decided to grow my beard and bleached my hair white. Hence I could not do any other shooting for the next seven or eight months. The hair and beard that you see in the movie is one hundred percent real. I had to shave off my entire head once the shooting was over, because due to the bleaching, it was not possible to dye my hair black anymore.”
