Yash Chopra had intended to film parts of the title song "Jab Tak Hai Jaan" in the Swiss Alps, a favourite shooting location of his. However, after his death the Switzerland shoot was cancelled, as Aditya Chopra did not want to tamper with his father's vision.
The romantic scenes of the film were directed by Yash Chopra's son Aditya Chopra to give the romance a more contemporary feel.
Katrina Kaif was often spotted smoking cigarettes with Shah Rukh Khan on the sets of the film, which led to some public controversy.
Chopra completed the film just before he died on October 21, 2012, at the age of 80 as a result of dengue fever.
