Retro is the flavour of Bollywood. Its little wonder why Priyanka Chopra, Ranveer Singh and Arjun Kapoor are donning the seventies avataar all for their upcoming film 'Gunday'. Shot in Kolkata, 'Gunday' is about two men rising from humble backgrounds to becoming the most powerful mafia. While Priyanka plays the rooted Bengali girl displaying the seventies, ethnic avatar, Arjun & Ranveer sport rugged looks. Not to miss is Ranveer's mane with the beard.
