It's based on the true story of Mahavir Singh Phogat, an amateur wrestler who lived for the proud dream of seeing his country take home athletic “gold.” Due to a lack of government sports funding, Mahavir wasn’t able to go for the gold himself. So he took his two eldest daughters, Geeta and Babita, and turned them into competitive wrestlers, cutting against the grain of what Indian society wanted and expected girls to be.
Aamir Khan, who had gained 25 kg for his role of a wrestler in 'Dangal', also lost the weight in 5 months.
It pays off in suspenseful bouts that haven't been hyperedited into incoherence, with actresses who really appear to be grappling.
In order to obtain the best film effect, all the actors were down to make movies. Amir Khan refused to wear prosthetic tights, and accepted wrestling training for half and a year with actresses.The film scene may be only a few minutes or even dozens of seconds, but in order to make the film look more real, they made every effort to do the best, which was admirable.
