The much-awaited trailer will be launched on December 13 at the Madinat theatre in the presence of the film's actors Ranveer Singh, Arjun Kapoor and Priyanka Chopra along with director Ali Abbas Zafar, according to an official statement.
'Gunday' will be the first Indian film to have its trailer premier at DIFF, it said.
The film is based in Kolkata during its most unsettled times in the 70s and deals with the inseparable life of Bikram and Bala, who grew from being small time, inconsequential coal thieves, to becoming the most powerful black marketing mafia men.
