The choreographer-filmmaker Farah Khan was in Iceland to choreograph a song from upcoming film 'Dilwale'. It features Shah Rukh Khan and Kajol and it's a one-take song. Farah decided to choreograph this track on Shah Rukh's insistence.
When the song was being shot, the weather was very much cold in Iceland. By using her sense of humour, Farah found the best way to beat the cold. Farah kept hugging her best buddy Shah Rukh Khan for keeping herself warm in the chilly Iceland weather!
