The movie is a real life story based on Mahavir Singh Phogat who trained "dangal" to 6 girls, 4 of them were his very own while 2 were that of his brother. Interestingly, all of them won medals at some or the other level!
After gaining 28 kg. for the initial shoot, Aamir Khan lost 25 kg. in 20 weeks to portray the younger (25 years old) character of Mahavir Singh Phogat.
Lead actor Aamir Khan and director Nitesh Tiwari reportedly auditioned 3000 girls for the role of Babita Kumari and Geeta Phogat, the two daughters of Mahavir Singh Phogat.
Dangal is the highest grossing Indian movie in the history of Indian films after surpassing Bahubali 2 by its release in China with more than 2000 crores.
