Perfectionist Aamir Khan feels he should not have taken the role of a college student in 3 Idiots.

“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, who was in the capital on Monday to launch the book ‘Colours of my Rainbow’ by Himani Verma.

The book tells the story of struggles of Salma Ansari, wife of the Vice President of India Hamid Ansari, to set up schools to marginalized and underprivileged children in Aligarh.

Aamir said he was drawn towards the subject of education in movies after directing Taare Zameen Par.

“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.

Aamir flew down from Berlin where he is on the jury at the Berlin Film Festival.
