Director Tigmanshu Dhulia’s Ghamasaan released on September 11, while his next with Nawazuddin Siddiqui, Woh Phir Kabhi Dikha Nahi, is in the last leg of making. Even as he has been busy with these two projects, a story has remained constant in his mind — the biopic of late filmmaker K Asif of Mughal-e-Azam (1960) fame. “Ghar bhi chalana hota hai. So, when some projects come my way, I have to halt the process of writing the film,” Dhulia told mid-day.
