I should not have acted in `3 Idiots`: Aamir

He won hearts with his portrayal of an engineering student in blockbuster `3 Idiots` and Bollywood superstar Aamir Khan says the only reason he decided to act in the film was that its subject was education.

“I shouldn`t have acted in `3 Idiots` as in no way do I look like an 18 year old. The only reason I did the film was because it was about education,” said Aamir.

The Rajkumar Hirani-directed film is the story of three students in an elite engineering institute reeling under pressure from the current educational system to excel in their career.

The 45-year-old actor has been passionate about the cause of education ever since he made `Taare Zameen Par`, the tale of a dyslexic child`s struggle to cope with the existing norms of education.

“I was drawn towards stories about education ever since `Taare Zameen Par` and then `3 Idiots` happened. Cinema has the ability to reach out to people and more films upholding this cause should be made,” said the actor.
