Even though she plays an architect in the film, sources tell us that Deepika ended up reading a lot of material on medical ailments and medicines as several scenes required her to tend to Mr.Bachchan, who plays her father, in the film. Confirming the news, Deepika says that she, "...spent hours going through information about various medical issues, and their symptoms, solutions, etc. I now know the basic details about blood pressure, constipation, etc."
'Piku' is a roller coaster ride of a crazy father-daughter relationship essayed by Amitabh Bachchan and Deepika Padukone with Irrfan Khan top lining the cast, in a pivotal author backed role.
