Though Arjun Kapoor and Ranveer Singh are playing mafia-men in their upcoming movie 'Gunday', the actors feel that the biggest don on the film's sets is lead actress Priyanka Chopra. "She is the boss of the sets. She is our madam. The biggest Gundi (lady don) on the sets is Priyanka Chopra," chuckled both Arjun and Ranveer. The film revolves round two dons of Kolkata from the 70s essayed by Ranveer and Arjun, with Priyanka, who enacts the role of a Bengali girl Nandita, being their love interest. Talking about the film, Ali said, "It is a fictional story but based on lot of real life events that happened between 1971 and 1988. It is the story of Bikram and Bala who start from being small-time wagon breakers and with time become black marketing mafias."
