Snow was essential for the story, the entire unit went to Simla in mid-Jan. It was cold but there were no sign of snow. Since the unit could not wait, kilos of salt bags bought from the local market & snow making machines from Bombay. The shooting was done nearly at 4 am that day. When the locals emerged out they were amazed to see so much snow. It looked so authentic that they would touch it to check whether it was real. The day after the unit left Simla, it snowed heavily.
