Mumbai, Feb 5 (ANI): Bollywood legend, Amitabh Bachchan, promoted his upcoming movie, 'Shamitabh', along with the film's director, R.Balki, on Wednesday in India's entertainment capital Mumbai, just days ahead of its release.

The two trailers of the film, launched last month, have generated much curiosity among moviegoers. The trailer showcases him in a rugged look with heavy beard and unkempt hairstyle. Indian actor, Dhanush, is surprisingly seen in an identical avatar in the promo. He plays the role of a deaf and mute man to whom Amitabh Bachchan lends his voice. This is his second Bollywood film. His debut movie 'Raanjhana' had won him many accolades. Actress, Akshara Haasan, is making her Bollywood debut with 'Shamitabh'. It is set to release on 6th February 2015.
