Bollywood's Mr. Perfectionist Aamir Khan, who is all geared up with his upcoming film 'Secret Superstar,' also has a secret dream which is still to be achieved. While talking exclusively to ANI, Aamir shared, "My dream is to make Mahabharat one day, which I have not yet achieved or I have not even moved towards it." Adding more to it, the 'Dangal' actor said, "It's too scary as a dream, maybe that's why. It's a big dream and so let's see if I can do it one day. " 'Secret Superstar' is based on a teenage girl named Insia, played by Zaira Wasim, who sets out to follow her dream of being a singing superstar under the confinement of anonymity. The film will also feature the 'PK' actor in a never seen before quirky avatar as a music composer Shakti Kumarr. Produced by Aamir Khan, Kiran Rao under the banner name of Aamir Khan Productions, Zee Studios, and Akash Chawla, 'Secret Superstar' is written and directed by Advait Chandan. The film is slated to release on October 19.
