Shah Rukh, who has worked with Chopra in several films, such as, Darr, Dil Toh Pagal Hai, Veer Zaara and others, says a small portion of the song that remains to be shot will not be shot as it would not match the vision of Chopra. “Just a minute and a half portion of the song was to be shot in Switzerland. We will make it impure if we shoot for it now,” Shah Rukh said. The film is directed by Chopra and also stars Anushka Sharma. It will hit theatres on Nov 13.
