'Sanju' producer Vidhu Vinod Chopra said he was unhappy when director Rajkumar Hirani informed him that he wanted to cast Ranbir Kapoor as Sanjay Dutt, while adding, "I thought someone...like Ranveer Singh could play this role much better." Vidhu further said, "I thought Ranveer had the flamboyance, the emotional depth...the ability to change himself completely to play Sanjay Dutt."
