You won't recognize Aamir Khan these days if you haven't seen him anywhere after PK. The actor has gone through a complete transformation since the release of PK in December last year. He is currently preparing for the character of a wrestler in his upcoming film Dangal, and for that he has put on a lot of weight. Aamir Khan is known to be a perfectionist when it comes to acing the 'look' of a character. He turned into a girl for a song in Baazi (1995). Later he grew his moustache in Mangal Pandey (2005), and beefed up considerably for Ghajini (2008). Recently, he cut down a lot of weight for PK. This is Aamir Khan's most bulked-up role so far. Interestingly, the 50-year-old actor needs to play two phases of his character in Dangal and for that he will have to lose weight again after the first phase of the shooting gets over. Frequent weight change might not be a good idea, but then Aamir takes the 'perfectionist' tag too seriously, and that makes his fans a little worried about his health.
