Shah Rukh Khan has floored women with his romantic charms, but there’s something that even Bollywood’s top most actor finds extremely difficult to do. Revealing what scares him the most from doing, Shah Rukh Khan says, “I cannot actually laugh on camera. I have a lot of problem there. I find it very difficult! That is one of the many problems that I face as an actor.” One of his initial directors, Kundan Shah, with whom he had worked on ‘Kabhi Haan Kabhi Naa’ (1994), had given the actor an earful while shooting. “Kundan has really shouted me for my acting and choice of films at times. He once told me, ‘I can make a stone act, but not you.’ He has the right to say that. Kundan has been like a father to me,” Shah Rukh Khan further reveals.
