Bringing Amitabh Bachchan and Irrfan together in his film, Piku, was some thing of a feat for filmmaker Shoojit Sircar. He elaborates, “Both are stalwarts from different schools of acting. Irrfan is an international star in the true sense of the term, and he coming with the legend of Hindi cinema was a big moment for me. I was very excited and also a bit sceptical on the first day of the shoot when Mr Bachchan and Irrfan met on the sets, it was a Robert De Niro and Al Pacino kind of moment for me. But it all went well. They hugged each other saying, so finally we come together and sat down to chat.“ The film talks about Deepika's relationship with her father (Bachchan) who spends most of his time obsessing over age-related issues. Irrfan, who plays Deepika's love interest, is considered to be an intruder in their family by her screen father. “There is a little bantering in the story line as the father wonders what Irrfan is doing in his family while the latter thinks that he's not intruding but he's sucked into the family,“ says Shoojit, further adding, “The megastar's chemistry with Irrfan is one of the highlights of the movie. When Irrfan is acting and when not, it is difficult to tell, and we were completely mesmerised by Big B.“
