Shah Rukh Khan has floored women with his romantic ways, but there’s something that even this actor finds extremely difficult to do. “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 have as an actor,” reveals Shah Rukh Khan. The actor also revealed that one of his initial time directors, Kundan Shah, with whom Shah Rukh has worked on ‘Kabhi Haan Kabhi Naa’ (1994), had given the actor an earful while shooting.
