"Shonali heard the song through a common friend Amitabh Bhattacharya, the National Award winning lyricist, and fell in love with it. She wanted something like this to kickstart a very essential part of the movie. She liked it for its anthemic feel. She felt it contained the essence of youth and optimism," says Barua, who hails from Jorhat in Assam and is based in Mumbai.
"'Dusokute' was originally part of our Assamese album 'Looking Out of the Window' (2010). This was a song done looking back at life, when I was a student of Gauhati Commerce College. Those times gave me a terrific feeling - a kinetic energy or force. That was the genesis of the song," 40-year-old Barua told PTI.
"After hearing this song by Joi I loved it so much that I asked him if we could have it for 'Margarita' and put it in Hindi. Prasoon penned such amazing lyrics for it lifting it to another level," she says.
"From a narrative stand point it fit perfectly that I found an original Assamese song. The boy Laila falls in love with - Nima - is Assamese. I made him Assamese in the script because wherever possible I try to bring in different underrepresented communities in the film.
"And I present them as the mainstream by avoiding the pitfall of exploring their minority identity or issue. There are many kinds of Indians - not just generic north Indians (as Bollywood portrays) and when we see them on screen it should be about who they are as people - not stand-ins for their communities.
