Bollywood megastar Amitabh Bachchan, who is currently shooting for Shoojit Sircar's "Piku", has recently revealed his look from the film.

Known to get into the skin of each character he portrays, Big B has completely transformed himself in the film and is seen sporting a huge tummy. He is also wearing a fashionable hat and a pair of big framed specs.

Although, Shah Rukh Khan and other stars' eight pack abs have become a new trend in Bollywood, Sr Bachchan's family pack will surely make his fans love the actor's never-seen-before avatar.

Reportedly, the "Paa" actor has also put on weight to make his family pack look realistic to a certain extent.

Bachchan took to Twitter to share his new look from "Piku". 

Apart from Big B, "Piku" also features Deepika Padukone, Moushumi Chatterjee and Irrfan Khan in pivotal roles. A few days back, Bachchan had posted a photo from the rehearsal moment on his official Facebook page. In the photo, apart from Big B, Padukone and Chatterjee were also seen rehearing their dialogues.
