Abhishek Bachchan is currently shooting for his upcoming film ‘Bob Biswas’ in Kolkata, and on-location photos of the actor in action went viral on Thursday. Facebook, Instagram and Twitter are flooded with photographs of Abhishek’s look as the titular ‘Bob Biswas’, which have reportedly been leaked from the film set. His co-star Chitrangda Singh has also been clicked on the set of the film. In one photo, the actress can be seen wearing a red frock, wristwatch on her left hand and a pair of grey-blue sneakers. In another photo, she wears a blue saree with a brown short-sleeved blouse, carrying an off-white shawl and a black vanity bag. ‘Bob Biswas’ is a spin-off from the 2012 hit, ‘Kahaani’ starring Vidya Balan. ‘Bob Biswas’ marks the directorial debut of Diya Annapurna Ghosh. In the spin-off, Abhishek’s look has been created keeping in mind that of noted Bengali cinema actor Saswata Chatterjee who had played the character of the serial killer Bob Biswas in Kahaani. From what we see in the viral photographs from Kolkata, Abhishek has been given a beefed-up look for the role. His hairstyle is similar to Saswata Chatterjee’s, with a bald patch. He also wears a pair of old-fashioned glasses. The actor is dressed up in blue and black checked full shirt and grey trousers, with black shoes and belt.
