His 2007 film 'Taare Zameen Par' received accolades from both critics and viewers. The 47-year-old actor had also worked as an assistant director for his filmmaker-uncle Nasir Hussain's movies like 'Manzil Manzil' (1984) and 'Zabardast' (1985).

“I have a story that I have chosen and hope to direct. But right now I have responsibility as an actor, plus I have (TV show) 'Satyamev Jayate' season 2,” Aamir said.

“The script is written by someone else. I have told the writer it (direction) will take time. I don't know when I would direct next. As I have 'Peekay', 'Dhoom 3' and 'Satyameva Jayaate 2' in hand. I might produce it as well,” he added.

Aamir said that he is fascinated with 'Mahabharat' and will love to be a part of the epic's presentation on big screen one day.

“It is a desire. The project is huge. It is a dream project for me. But if I decide today that I am making it, I will have to give 20 years to it. This is why I am scared, if I say yes and decide to make it, five years will go only in research and then to execute it....The material is very exciting for me,” he said.

Aamir also cleared the air on reports of creative differences between him and director of his upcoming movie 'Talaash' Reema Kagti.

“As far as Reema is concerned, these rumours are not true. Lots of times they are untrue. Like 'Lagaan', this time around also there was something about me not being happy with the film. If I go around explaining every rumour I will have to stop working. I have to let go and decide that ultimately the film will speak for itself,” he said.

“It's been wonderful working with Reema. She is in control of the material and confident about what she wants. She is very clear about how she will get it. She doesn't compromise,” Aamir said.

“I felt comfortable and safe in her hands. At a number of places, she was able to point out layers in my character and scenes which I had not thought about. I was quite amazed by her perceptiveness and understanding of the moment.”

Besides Aamir, 'Talaash', which releases on November 30, stars Kareena Kapoor and Rani Mukherjee in the lead.

“I don't think I have ever done a film where I haven't given my opinion. Sometimes it is taken and sometimes it is not. But I trust my directors. When a director is working, everyone gives opinions,” said Aamir.
