Fans have been going crazy anticipating Shah Rukh Khan and Farhan Akhtar’s return with ‘Don 3’. However, the film is a long way to go. Writer, director and actor Farhan Akhtar reveals, “I am also excited about ‘Don 3’, but let me write it first. I have a thought in my mind and I will take my time and write it. I don’t know when it will happen as I have not written a single word.” While ‘Don 3’ is still to get scripted, Farhan is busy working on ‘Rock On!! 2’ for which he is growing his hair.
