Here one can remember that Juhi Chawla and Karsima Kapoor acted together in 1994s film Andaz opposite Anil Kapoor, it was the remake of Tamil film Sundara Kandam of 1992.
At some point, it appears to be true that Juhi Chawla is responsible for Karisma's stardom because once Juhi Chawla had taken wrong decisions in her filmy career and she rejected good offers to act in the big films like Raja Hindustani and Dil To Pagal Hai and these two films became blockbusters and brought Karisma Kapoor a stardom. But it's also true that Karisma Kapoor did put good efforts, gave her best performances in both the films and she utilized those opportunities in a good way.
Before these two films Karisma acted in several films but they didn't receive that much of success which she received through Raja Hindustani and Dil To Pagal Hai.
Later Juhi Chawla regretted for her wrong decisions for rejecting to work in block-buster films like 'Raja Hindustani in 1996 and ‘Dil To Pagal Hai’ in 1997. Juhi Chawla stated in an interview that she was the real cause for Karishma's stardom and herself a stupid person.
In Raja Hindustani, which was released in 1996, Karisma looked beautiful and impressed the audience with her stunning performance. This film has become Karisma's biggest hit and one of her best performances. Indeed, Juhi’s rejection became a turning point in Karisma's filmy career.
The reason for Juhi Chawla to reject to act in Dil To Pagal Hai was she had to act as a second leading actress that too beside her strong competitor Madhuri Dixit, it was not acceptable for Juhi. Not only Juhi, many actresses like Manisha Koirala, Kajol, Urmila Matondkar had rejected the role because they were not ready to perform as a second leading actress. It had become a challenge for Yash Chopra to get a heroine to act alongside Madhuri.
Earlier even Karsima hesitated to accept the role but when Yash Chopra re-approched Karisma she agreed to do it and she took it as a challenge, acted very confidently and won National Film Award for Best Supporting Actress for Dil To Pagal Hai. Apart from Juhi Chawla the actresses who rejected the role in Dil To Pagal Hai also definitely might have regretted for their wrong decisions.
