A still from Dangal.UTV Motion Pictures/ Twitter

While Dangal was being shot, the general opinion was that it would be eerily similar to Salman Khan's Sultan as both the films have wrestling as the central theme. Now that the Dangal trailer is out, some of the social media users have tagged the film as a better version of Sultan, while the rest said the three-minute-long clip reminded them of Salman's sports-drama.

Directed by Nitesh Tiwari, Dangal is essentially a biopic on wrestling coach Mahavir Singh Phogat, a role Aamir Khan seem to have mastered effortlessly. Pitch-perfect accent and unbelievable physical transformation, clearly Aamir didn't take two years to make Dangal for nothing.

Scheduled to be released on December 23, Dangal comes two years after Aamir's last film — PK. So, what took so much time? Aamir piled on 22 kilograms and lost them all to play the younger version of Phogat in Dangal. He followed a strict calorie-count diet and worked out regularly to get the desired shape.

Interestingly, this isn't the first time that Aamir has gone to such extremes to fit a role. Dhoom 3, 3 Idiots and Ghajini are some of the films, which required the superstar to hit the gym and watch his diet closely.

Here's what social media users have to say about Dangal trailer:
