Mid January, Rajkumar Hirani kick-started the filming of the much-hyped Sanjay Dutt biopic that’ll star Ranbir Kapoor in the lead. The film also features Sonam Kapoor as Sanjay’s earlier love interest, Vicky Kaushal as his friend from the US, Anushka Sharma as a journalist and Paresh Rawal as Sunil Dutt.
