In the movie there is a scene where Mahie Gill's character asks Deepak Dobriyal's character if she resembles Tabu, which is a reference to the actress Tabu. This is because many people in the industry at first glance have complimented Mahie Gill that she looks so much like Tabu, and even the actress Tabu herself has commented this. So Anurag Kashyap wanted to put this idea in the movie.
According to the director Anurag Kashyap, this movie is dedicated to the song "Yeh mehalon, yeh takhton, yeh taajon ki duniya. Yeh duniya agar mil bhi jaaye toh kya hai" and its lyricist Sahir Ludhianvi from the Guru Dutt movie Pyaasa (1957).
