That ace actor Irrfan Khan and Bollywood's global superstar Shah Rukh Khan shared a great rapport on the sets of BILLU, is a news known to one and all, but off screen too, their friendship is slowly building up into one of genuine affection and respect towards each other. Irrfan Khan reciprocated the favour done to him by SRK (giving him a lead role in his home production) by doing a cameo for SRK's Red Chillies television show, GHAR KI BAAT HAI, thus dispelling all rumours that he is not very pleased by the fact that SRK is being given the prime position in the promos of BILLU. In fact he is looking forward to doing more films with King Khan in future!
Irrfan is highly appreciative of Shah Rukh Khan and says that the best thing about SRK is that even though he is at the top, he is not at all insecure. That's what makes Shah Rukh different from others. And so, SRK was not afraid of giving him the plum footage, in a role which gave Irrfan a lot of scope to showcase his acting talent, while he himself played an extended cameo, as it was the demand of the script. Never once did Shah Rukh try to steal Irrfan's thunder, and went out of his way to see that Irrfan's character (which is so vital to the film) was developed and highlighted properly in the film.
Well, that's what makes a confident, secure superstar!
