Whatever the numero uno film production house Yash Raj Films does, has to be unique in its own standards. The other day the news that Bappi Lahiri would sing a Bengali song for Gunday caught the eye of the people and so did another news of the famous Dhoom Machale Dhoom song being recorded in Arabic. Now the trailer of Gunday will be unveiled at the ongoing Dubai International Film Festival (DIFF). All these days trailers of films were released in cinema halls, television shows and YouTube. The trailer would be launched at the Madinat Theatre on 13 December in the presence of the film’s stars Ranveer Singh, Arjun Kapoor and leading lady Priyanka Chopra along with director Ali Abbas Zafar. Curtains of the festival would be drawn down on 14 December. Based in Calcutta during its most unsettled times in the 70s, Gunday deals with the inseparable life of Bikram and Bala who grew from being small time, inconsequential coal thieves, to eventually become the most powerful black marketing mafia-men. The film is slated to release worldwide on 14 February next year.
