All shots inside Toyota Innova are taken after removing first row headrests. Probably this was done to capture Amitabh Bachhan in the same frame as Irfan or Deepika. Driving without headrest is very dangerous for the first row passengers especially on highways.

The girl playing harmonium spotted by Bachchan while cycling through Kolkata is director Shoojit's daughter Anannya.

In the last scene of the film, Deepika Padukone is shown playing badminton with Irrfan Khan. Deepika was a national level badminton player before turning to modeling. Her father Prakash Padukone is also a former international badminton player.

Parineeti Chopra was the initial choice for the lead role.

Only film to star Irrfan and Amitabh.
