Filmmaker Kabir Khan says that the cameo in Salman Khan starrer Tubelight was screaming for superstar and hence Shah Rukh Khan graciously agreed to do the role. “I am not going to divulge much details about the role. Let the film come out. It is a cameo, which was screaming for a superstar so we went to Shah Rukh and asked to do the special role. He graciously agreed to do it,” Kabir said at the success party of Dangal recently.
