No challenge to Amir khan in film industry. This was one of the best movies of recent time. We except more such movies from bollywood. This needs to be the face of bollywood globally and not those stupid high budget movies with point less item numbers and party songs. Hats of the dangal team. It is good work really. And all actor s in the movie were exceptionally good. Perfect casting perfect choreography all good in this movie. I like it. I saw dangal movie 5 times. You can learn many more from dangal movie.
