New Delhi, Feb 08 (ANI): There has been another addition to the much-anticipated biopic on Sanjay Dutt, starring Ranbir Kapoor directed by Rajkumar Hirani. Manisha Koirala, who has featured in numerous films as Sanjay Dutt's heroine, will be soon seen playing role of his mother Nargis Dutt in the film. Confirming the news to Mumbai Mirror, Hirani said, "Manisha is playing Nargis ji. She's a wonderful person, extremely sweet." Hirani said, "We were thinking of many actresses. And while Manisha is really pretty and a fantastic actress, my primary reason for taking her is that she's a cancer survivor and having been through the journey herself, can identify with Nargisji's fight with the Big C. When we met, she told me a little about that journey," The casting for the main characters seems to have fallen in place now, as Paresh Rawal will play Sanjay's father Sunil Dutt, Dia Mirza would be his wife Maanayata. Anushka Sharma will essay the role of a journalist and Sonam Kapoor is one of the actresses he was romantically involved with. Manisha has been missing from the big screen in Bollywood. Her last notable Bollywood film was Ram Gopal Varma's 'Bhoot Returns' which had released in 2012. The film is reportedly gearing up for release during Christmas this year.
