Shah Rukh Khan is currently busy shooting for Aanand L. Rai’s ’Zero’ which also stars Katrina Kaif and Anushka Sharma. It looks like after finishing this comedy, he will get back to his popular ‘Don’ franchise. According to reports, SRK will next start shooting for ’Don 3’, which will be helmed by Farhan Akhtar. For the time being, the script is being perfected so that by the time King Khan finishes ‘Zero’, it is ready to go. Farhan too has always said that ‘Don 3’ was definitely happening, but that he wasn’t sure about when. So it is indeed a splendid development if reports are to be believed, considering the massive popularity of the first two installments.
