To get the special look for the character, director R. Balki roped in Hollywood make-up artist Stephan Dupuis.The prosthetic process was arduous. Around eight pieces of specially-crafted clay models were meticulously stuck on to the face. Once the process started, it was impossible to move even a few centimetres. Eating and drinking had to be avoided and he couldn’t talk because it would have displaced the pieces. The entire process took four-five hours every day over 45 days of continuous shooting. He was even willing to go through the process of showing his eyeballs bulging out to give a more authentic look to the character, but doctors said that would require injections in his eye every two hours which could affect his vision.
