"All those students had yellow books and I was so scared that my books would become yellow, that I refused to eat with them. So I got the reputation of being a snoot because I would eat my own lunchbox and I never wanted to share my dessert," he added.
Karan says ultimately found a friend who has been with him till today, Dharma Productions' CEO Apoorva Mehta. "No one wanted to be my friend because of my lunchbox because I never shared my lunchbox. One day the principal walked in and said no one is friends with Karan Johar, who will be his friend? My CEO today put his hand up there and said, he will," he said.
The Lunchbox is helmed by debutant director Ritesh Batra. It hits theatres in India Sep 20 and stars Irrfan, Nimrat Kaur and Nawazuddin Siddiqui.
