Development and Filming

In June 2011, Yash Raj Films released a statement announcing a new directorial venture by Yash Chopra
which would coincide with the 50th anniversary of his career in Bollywood. The producers also
announced that the film would release on the Diwali 2012 weekend. According to Chopra, the film was
planned in early 2009 but he did not want Khan to work on any film other than his simultaneously.
In an interview with The Telegraph he said, "My film is an emotional film. It is not comedy, action,
escapism...This is what we call an internal film. There are only three characters their emotions,
happiness, sadness."

He also stated that the film was untitled at that time, similar to his previous project Veer-Zaara
which was named on the day of its submission to the Central Board of Film Certification. The producers had considered a variety of options for the title but were reportedly not satisfied with any of them. In September 2012, it was officially announced that the title of the movie was Jab Tak Hai Jaan. The title seeming to have been inspired from a song of the same name from the 1975 hit film Sholay.
Initially the film's principal photography was expected to commence in November 2011. However, it had
to be delayed since Khan wanted to take a break after his two releases in 2011, Ra.One and Don 2.
Principal photography officially began on January 9, 2012 at Yash Raj Studios in Mumbai, where a significant portion of the film was also shot.
After the schedule in India, the crew began a 35-day filming schedule in London beginning on February 22, 2012. The film was shot under the working title of Production 45. Khan arrived in London on February 21, 2012 and completed filming his appearance on March 26. During filming, photos of the actors on the sets were leaked on the Internet, inciting a camera ban by the producers and an increase in the amount of security for the film's production.  A number of locations throughout the city featured in the film, including the Borough Market, Jubilee Walk, the Tower Bridge and Canary Wharf. A car crash sequence was filmed at Shepherd's Bush by closing down four streets in the area. The schedule was completed on March 27, 2012 at an indoor location in East London. The romantic scenes of the film were directed by Chopra's son Aditya Chopra to give the romance a more contemporary feel.  The climax of the film, initially planned by Chopra to be shot in the mountains of Kashmir, was relocated to Ladakh. This was apparently a suggestion of Khan whose movie Dil Se.. had been shot in the area many years earlier. However, portions of the film were later
filmed in three different cities of Kashmir—Srinagar, Pahalgam and Gulmarg.

Marketing

A teaser trailer was released along with the theatrical release of Ek Tha Tiger as well as through the

remained untitled as "A Yash Chopra Romance." The teaser crossed over one million views in less than
