The film was in the making for 4 years
This movie started filming in 1997 and was supposed to be released on July 1, 1998, which would have been Preity G Zinta's first film but for some unknown reasons and delays, it was postponed to 2000. Therefore, several of Zinta's films got released before this one, including two of her Telugu films.
The producer Ramesh Taurani wanted to replace Chandrachur Singh mid way through the film. The movie was not getting any distributors and Chandrachur's slow box office draw was being considered the reason. Ramesh Taurani wanted Salman Khan to step in Chandrachur's role. But Chandrachur needed to sign a legal document saying he was fine with the producer's replacing him. He refused to sign the document and shooting was stalled for 6 months.
Producer Ramesh Taurani had no faith in the box office draw of Saif Ali Khan and Chandrachur Singh. This is the reason he made Preity Zinta the only main focal point in all the film's publicity and pictures. Saif and Chandrachur's face was placed at the back of the CD album cover of the film.
The title song "Kya Kehna" has been inspired from "Oh! Carol", an international hit written by Neil Sedaka in 1958. The Pakistani version was from the film Thori Si Bewafai and titled " O Melo Na Jaana Mujh Se Door".
