Nikhil was keen that his lead actors, Imran Khan and Kangana Ranaut be extremely comfortable with each other, so that the chemistry comes off as natural. Our source says, `Eventually when the time came to shoot these scenes Nikhil took all possible measures and ensured that very few people were present on the set during the making of these scenes. He was both surprised and relieved that Imran and Kangana were not in the least nervous and they ensured that the scenes were perfectly captured. They were so professional that the whole thing was wrapped up quicker than expected. Nikhil was very satisfied with the shots.`
