Aditya Roy Kapoor came drunk on the sets to play the part convincingly but the shot had to be canceled as he would be completely out of sorts.
The film made Shraddha and Aditya Roy Kapoor famous and won them praise and also gave them their first 100 Crore Blockbuster.
Before they started filming for the movie, Aditya and Shraddha did a workshop together to break the ice and get more comfortable with one another.
This movie is a remake of the Hollywood movie "A Star is Born" (1937).
Both Imran Abbas Naqvi and Sushant Singh Rajput were offered the role of Rahul Jaykar, both had to decline, because both were under contract for two different film productions.
