Ayushmann Khurrana spent time at a blind school to prepare for the role of a visually challenged man in the film 'Andha Dhun'. "I wanted to look 100 percent genuine on screen. It's extremely sensitive to portray someone who is visually impaired," he said. Ayushmann further said, "It was tough and rigorous and needed all the attention in the world."
