According to Khan, Mukerji was initially offered the role of Priya, but due to prior commitments, she turned it down. Post her refusal, Aishwarya Rai was signed for the role, but had to leave the film after some problems with her then-boyfriend, actor Salman Khan, who is said to have disrupted filming. This caused considerable delay in the progress of the film until Mukerji agreed to take over the role and save the film.

Contrary to the Hindi-media prejudice of fair skin being considered more attractive, Mukerji and Contractor received praise for her new, tanned complexion, including their use of smoky-eye, which was subsequently used in other films, most notably in Mukerji's Hum Tum (2004), Veer-Zaara (2004) and Kabhi Alvida Naa Kehna (2006).
