Bollywood's two biggest superstars Shah Rukh Khan & Salman Khan were together in the last scene of the film, where SRK made a guest appearance.
Tabu was signed for Preity Zinta' s role.
The character that Salman refers to as his Nanny - Mrs Goudhino, is a real life neighbour, from his old residence.
The film was originally titled " Chandralekha" just as the original film. However, the title name was changed because Chandralekha was a South Indian name, so it wouldn't fit a North Indian movie title.
When Tabu exited the film, Karishma Kapoor was signed. She too left the film.
