Superstar Aamir Khan has just unveiled the trailer of Advait Chandan’s directorial debut film ‘Secret Superstar’ and he’ describes his role as “tadka in the dal”.

“I have an interesting character in this film and it has been written and directed by Advait. It was Advait’s idea to come up with this look and I have never done a role like this before,” Aamir said at an event here.

“The story is about a girl, but I am a very integral part of this film. I am like the ‘tadka in the dal’,” he added.

‘Secret Superstar’ traces the journey of Insia, an aspiring singer – a 14-year-old Muslim girl from Vadodara, Gujarat. She takes to a burqa to hide her identity from her family while recording online videos of her singing.

Chandan, who has served as an assistant director on films like ‘Honeymoon Travels Pvt Ltd’ and Kiran Rao’s directorial debut ‘Dhobi Ghat’, says that he considers Aamir more than a godfather.

“He is a school for me. I wanted to go to a film school, but I got rejected from FTII. Ten years ago, I got a job as an intern in Aamir’s ‘Taare Zameen Par’, so since a decade, I think I am going to a film school.

“A few people get a godfather in this industry, but he is my film school,” he added.

But he said Aamir took up a role in ‘Secret Superstar’ based on his taste for the script.

“He says yes to a film only if he likes the screenplay. The only way to convince him is to give a great narration and a great script,” Chandan said.

Adding to this, Aamir said: “I was very convinced with the script, but whether I want to play this role or not, I wasn’t sure.

“I wanted to produce this film. When Advait asked me to play this character, I was not sure because it was completely different from who I am. So I gave a screen test and then we felt I can do this role.”
