But since the film Shanghai is a political thriller and not a love story, director Dibakar Banerjee was worried about adding a song that has no connect with the film as he didn't want it to stand out like a sore thumb in the film.
Hence, Dibakar discussed the song with Emraan and they both decided that Dibakar would shoot the song himself so that the film retains its continuity.
And in true Dibakar style, he has used a disadvantage into an interesting angle. Now the song will be shot as a sequel to the film and will show Jogi Parmar's (Emraan's name in the film) life after the film.
The song has been completed and will soon be included in the film too.
