With a career spanning over 30 years and having acted different shades of characters including dark and comic roles, or a common man struggling against the system, actor-director Pankaj Kapur believes he hasn't done enough and wants to explore more.

"There are millions of people in the world, I have only played a few of them. And I don't think I have done enough, I would like to explore more. So I look forward to doing many more characters, as long as I am fit and alive. I enjoy playing different kind of people," Kapur told PTI in an interview.
