Shoojit Sircar's comedy drama 'Piku' promises to leave you in stitches. Starring Deepika Padukone and Amitabh Bachchan, the movie crew has something amusing to share from the movie sets.

Latest one being the entire cast and crew calling Big B 'Baba', Deepika, who plays Amitabh's daughter in the film, started calling him Baba off camera as well.

A source says, "Yes, Deepika does call him 'Baba' on and off the sets."

And if that wasn't enough, the moment everyone on the sets came across this term, they all joined Dippy in it.

The two are bonding well while shooting for the movie. Big B was often reminded of his daughter during the shoot.

Produced by MSM Motion Pictures (a division of Sony Entertainment Network), in association with Saraswati Entertainment Creations Limited and Rising Sun Films, 'Piku' will release worldwide on April 30, 2015.
