Superstar Aamir Khan dreams of bringing the epic tale of Mahabharata on the big screen, but says he lacks courage to do it. “My dream is to make Mahabharata and I don’t know if I will be able to fulfil this dream or not. It is a very difficult dream and a scary dream, because every time I think about it I feel I won’t be able to do it. I am unable to gather the courage,” Aamir said at the Agenda Aaj Tak held here Friday. “It is such a huge responsibility. I don’t know if I will be able to fulfil it or not. This subject has been in my heart from a long time,” he added. Asked what character he would want to play from the epic story, the 47-year-old said: “My favourite character is Karna. But I feel I won’t be able to do that role. I don’t suit the character. I think I would suit the role of Krishna.” Meanwhile, the actor is riding high on the box-office success of his suspense thriller Talaash.
