They participate in a social experiment “What Can You See When You Can’t See” to promote the trailer, where they undertake the challenge to guess an object by using every other sense but that of sight. The exercise is geared towards understanding the importance of each sense, and how the absence of one can render humans fearful and helpless. Sriram Raghavan is known for his genre-redefining films, from Johnny Gadar to Badlapur. His next, Andhadhun, which has already created a social media stir with its quirky posters, stars Tabu, Ayushmann Khurrana and Radhika Apte. The poster , which released on 20 June, combines the most prominent themes of the film — music, crime, thrill and blindness. The film will see Khurrana play a visually impaired piano player, which explains the broken glasses on the poster. Presented by Viacom18 Motion Pictures and produced by Matchbox Pictures production, AndhaDhun is slated to release on 5 October .
