Ali Fazal began his career a decade ago with Aamir Khan-starrer "3 Idiots" and the actor says the superstar's hunger for knowledge has stayed with him throughout his journey. Ali, who had a cameo appearance in the Rajkumar Hirani-directed 2009 blockbuster, says the film was a learning experience for him.

"I used to always observe Aamir. Between takes, we would snap out and play chess and read books. That stuck with me for some reason. His thirst for knowledge, that even at that level the man was going nuts, trying to figure out and say 'I haven't learnt enough'," Ali told PTI.
