the part was his best role after Deewaar (1975), and said he only accepted the part because of "the fantastic script" by Aditya Chopra, whom he called "the little boy". To complete the casting, Chopra sought six new actors; three male and three female. Aditya's brother Uday Chopra wanted to make his acting debut in the film; Aditya Chopra and his assistants travelled across India to find the other five newcomers; he cast Shamita Shetty, Jugal Hansraj, Kim Sharma, Jimmy Sheirgill, and Preeti Jhangiani. A gymnasium was built specifically for their training before filming began. Amrish Puri, Shefali Shah, and Helen made special appearances. Aditya Chopra also wrote the film's dialogue. The principal photography of Mohabbatein was handled by Manmohan Singh and commenced on 25 October 1999, taking place in the United Kingdom.
