Shah Rukh Khan almost pulled out of the project:

The Kal Ho Naa Ho tune was composed in the German Bakery in Pune:

Nikhil and Loy (Mendosa) were sitting at the German Bakery, Pune and the filmmaker was humming the song, My Heart will Go On, because he wanted a similar song in terms of music for the film. And Loy came up with the tune that he recorded in his phone. Thereafter, Shankar (Mahadevan) and Ehsaan (Noorani) listened to it , and came up with the entire song.

Nikhil Advani was criticised for not showing a traditional death scene:

Film critic Komal Nahata called up Nikhil and had said, “How can you show death with such irreverence?” To this, Nikhil had replied, “I show everything with irreverence.” Even Shah Rukh wasn’t convinced about the scene. Nikhil, who didn’t want to show death on screen, said, “We wanted to show that Aman is still alive. So, in the final scene, after years later, Naina is shown talking to Jia, about Aman.”

The film was supposed to be shot in Toronto:

The film was initially set in Toronto. But later, the shooting location was moved to New York.
