Apparently, Aamir Khan reportedly wanted wrestling champ Sangram Singh to play the role of his main opponent in the ring for the film Dangal, so the fight in the grand finale could look more authentic.
Sangram's character had to lose the competition with Aamir though, which the Olympian wrestling champ refused to do. He told reporters that this wasn't an ego issue, but did it to preserve the dignity of the respect and love India has given him. He said he couldn't play a loser just for the pleasure of being seen on screen with Aamir Khan and disappoint his supporters in the process.
