We have all been witness to Amitabh Bachchan's knack for transforming into the characters he portrays. One look at the recently dropped trailer of Gulabo Sitabo and it is easy to see that he has seamlessly slipped into the part of the sharp-tongued landlord Mirza who tries to drive away his tenant, essayed by Ayushmann Khurrana.

Sporting a long beard, spectacles and a prosthetically-pronounced nose, Bachchan is unrecognisable in the comedy. No wonder then, director Shoojit Sircar was able to shoot sequences in the congested streets of Lucknow without locals realising that the megastar was in their midst.
