Karan revealed that he wanted Shahrukh, Tabu and Sanjay to play the lead roles with Nikhil Advani as the director. The film was named Kaal then. On narrating the story to Rensil D"Silva, the screenplay he prepared turned out into a different film all together. Thus born the title Kurbaan with Saif and Kareena in the lead roles.
Karan left Kurbaan behind after he went on to make films like Kabhi Khushi Kabhi Gham in 2001 and later produced Kal Ho Naa Ho.
