Film director Nikhil Advani started his career with the film 'Kal Ho Naa Ho'. This was his first film, which he directed. Recently, he revealed that neither Karan Johar nor he himself narrated the story of this film to Preity Zinta. Nikhil Advani said that the story of this film was narrated to Preity Zinta by Hrithik Roshan, and at that time both were shooting for 'Koi Mil Gaya'.

In a conversation with Mirchi Plus, Nikhil Advani said, "We were not there at that time." He further said that Shahrukh Khan or Karan Johar called Preity and told that Hrithik had heard the script. He asked Preity if she was ready to listen to it, and Advani said, "The film had its own destiny."

Nikhil Advani also talked about the producer of the film 'Kal Ho Naa Ho', Yash Johar. He said that he had shot the film for nine days in Toronto, but he was in depression at that time. When Yash Johar saw him in this condition, he asked the reason for this. Nikhil told him that he was not happy with the shooting of the film. Yash Johar listened to him and then sent him to New York.

This film, which was released in 2003, is still very much liked among the audience. Shahrukh Khan's film 'Kal Ho Na Ho' won the hearts of the audience with its emotional story. In the story of the film, Aman (Shahrukh Khan) teaches Naina (Preity Zinta) how to live life and love. In the end it is revealed that Aman is suffering from a serious illness and will die soon. Saif Ali Khan also played the role of the second protagonist in this film. 'Kal Ho Na Ho' is still considered a heart-touching film, and its songs, dialogues, and story have made it a classic.
