Aamir Khan who has built up his body for his character in Ghajini is going for another image change in next movie, 3 Idiots.

Directed by Rajkumar Hirani, the movie features Aamir as Ryan, a college student. Ryan is a handsome and adventurous guy who loves his friends more than his parents. For the softer look of a collegian, Aamir has to look leaner, slightly hunched and all covered up.

Aamir Khan is known to be inclined towards method acting, to the extent it is practiced in Bollywood. “He is not the kind who will appear shirtless only because he’s built this body,” according to a source.

Raj Kumar Hirani of Munnabhai Fame has etched out the role of Ryan in a unique way. and Aamir is trusting him completely with it.

“He’s not interfering on the sets and doesn’t even give his input to Raju,” the source said, “he’s concentrating on getting into his character and he’s got full faith in Raju’s script and direction.”

Based on Chetan Bhagat’s best selling novel Five Point Someone, the movie will start shooting in early December in Bangalore. Major part of the movie will be shot in Bangalore. Kareena Kapoor plays the female lead.

The movie will release in mid-2009.
