Director: 'Khan doesn't interfere on set'

Aamir Khan did not interfere on the set of 3 Idiots, according to the director.

Khan, himself a filmmaker, is renowned for challenging directorial decisions.

Helmer Raju Hirani told NDTV Movies: "The perception that Aamir interferes on the sets is a complete myth. Dedication cannot be called interference.

"Even if he has a suggestion, he will tell you quietly and say it is your call. He is the most non-interfering actor I have ever met."

He also praised the 44-year old for successfully playing a student much younger than himself in the coming-of-age comedy.

"He has taken a huge effort to look his character and looks much younger than what he was five years ago."
