Wrestler-turned-actor Sangram Singh has turned down a role in Bollywood superstar Aamir Khan's next film 'Dangal'.

'Dangal' is based on the real-life story of wrestler Mahavir Singh and his famous daughters Geeta and Babita Phogat.

"I was offered the film, the role was small. Also my character in the film had to lose a fight to Aamir which I felt was incorrect. I am a wrestler.. I feel I should promote positive things. I don't want to disappoint people," Sangram told PTI.

In 'Dangal', Aamir plays a wrestler and Sangram is all praise for the perfectionist.

"He is a brilliant actor... he is very focused and dedicated. He is excellent in whatever he does. He is a huge star and he playing a wrestler will surely spread positivity about the game," he added.

Currently, Aamir is busy shooting for the film which is slated to release next year.
