On the first day of the shoot, there was actually a sandstorm that hit the location and production was delayed by 7 hours.
On the last day of the shoot, fire broke out on the sets creating complete panic and chaos. It took the entire unit including actors as well as the locals four hours to put the fire out. Interestingly, there was hardly any water or other aid to put the fire out. The crew had to use drinking water to douse the fire.
The entire movie is shot at a stretch of 3 days in the Rann of Kutch, where the temperature was 49 degree Celsius.
Cast and Crew worked for almost 18 hours a day to finish the film on time.
