Ranveer Singh, Arjun Kapoor, and Priyanka Chopra will be present along with director Ali Abbas Zafar.
They will be a part of a conversation session with the audience and share the behind-the-scenes stories of the shoot. 'Gunday' is an action drama set in the 1980s.
Singh and Kapoor, both of whom have undergone extensive physical training for their roles, play Bengali thieves who get involved in the coal mafia. Chopra plays the female lead and love interest of the two men.
DIFF's 'In Conversation' events feature the world's most prominent figures in cinema in person, in front of a live audience. Hollywood actor Martin Sheen will also take part in the series this year.
