Aamir Khan has been undergoing tremendous physical transformation for his upcoming movie "Dangal." However, this is not the first time the actor is going to shock fans with an immense change in his physique and body weight.

Aamir had gained 25 kgs for his role of Mahavir Phogat in "Dangal," and now the actor is in the process of shedding the extra kilos to play a younger part in the film. The actor had surprised all with his muscular look in "Ghajini" (2008), and since has been seen changing his looks and body weight for every movie he has done.

After attaining a tough body for "Ghajini," Aamir slipped into the persona of a college student in "3 Idiots" (2009), shedding away his weight and muscles to a great extent. Then came "Dhobi Ghat" (2010), which presented him in a much leaner avatar. Aamir had attained a fitter body for "Talaash" (2012).

Mr Perfectionist was then seen in a very chiselled look in "Dhoom 3" (2013), followed by his "PK" (2014) avatar, for which he had shed some weight but maintained his abs and muscles. Now, Aamir is ready to come up with another challenging role in Nitesh Tiwari directorial "Dangal." The actor is known to get completely immersed into his on-screen character, adopting the mannerisms required and also transforming his appearance.

"Dangal" will present Sakshi Tanwar as Aamir's on-screen wife, while newcomers Fatima Sana Shaikh and Sanya Malhotra will portray his on-screen daughters Geeta Phogat and Babita Kumari, respectively. Here is a run-through of Aamir's varied looks in his past movies and upcoming movie "Dangal."
