"I don't believe that I am a successful person. I just like doing different roles, I have a passion for that," Siddiqui told reporters here today.
When asked what changes he feels in his life after the success of the film, which has grossed more than Rs 300 crore, the 41-year-old actor said, "I am the same as a person. I don't change but only the perception of people changes about me".
The actor described this as the most challenging role of his career.
"The physical aspects can be taken care of but portraying the mental strength of Manjhi was very difficult. My own 12-year-old struggle when I did not have any work to do helped me to prepare myself for the role. I could relate to my own struggle to seek inspiration," Siddiqui said.
"He has the power to be the superman in today's world. He made possible an impossible task," the National Award winning actor said.
