Recalling an incident, a source close to unit said, "Both Irrfan and Deepika were sitting and discussing an important sequence, when all a sudden both the actors were seen yelling at each other. Not knowing what to do the entire crew along with director Shoojit Sircar gathered around the actors and tried reasoning out but to no use." The actors stormed to their vans and didn't come out for half an hour.
When they were called for the scene, everyone on the sets were tensed not knowing what will happen, seeing their faces both Irrfan and Deepika started laughing their lungs outs, that's when director Shoojit Sircar and the crew realized that the duo had planned the prank together.
The trailer of the film is loved by all, but what has caught everyone's attention is the unusual pairing of Irrfan Khan and Deepika Padukone. Their chemistry, is really refreshing on screen, sources close to the film said, "Irrfan and Deepika shared a health chemistry off screen which is quiet visible on screen."
