Shoojit says when he approached Big B with the film, the megastar was apprehensive and was convinced only when the director enacted few scenes from the movie.
"Honestly, I never thought Mr Bachchan or Deepika would ever do a film like 'Piku'. The first time I gave him the script, Mr Bachchan was in London. I met him when he came back and I could see a lot of notes he had made on the script. I saw apprehension on his part.
The director, who is also known for films like "Yahaan", "Vicky Donor" and "Madras Cafe", said he completely understood the reluctance of both his lead stars as "Piku" was not "Bollywood kind of" movie.
"I think actors do need some hand holding to know what they are doing. 'Piku' is not at all a film in the Bollywood kind of way. It took me few hours to convince Deepika but she agreed after I narrated her a scene from the film."

The director even made Deepika watch Ray's work to understand "Piku" as the film has heavily drawn for Ray in terms of simple-storytelling, music and real characterisation.
"In all my films I try and take influences from Ray's films and try and adopt them. It is mandatory for my actors, writers to watch Ray's films. I made sure Deepika saw one of his films. I feel for a film student, watching Ray is a basic learning."
"The struggle is on. It is difficult to make movies on your own terms and also to make a film and convince somebody to have faith in it. It is an internal struggle. It is easier to make a film but difficult to make it on your own terms.
"In that sense 'Madras Cafe' was a very satisfying experience. It is a precious film. It was hard core political; there was nothing peripheral about it.
