Harinder Sikka, who wrote 'Calling Sehmat' which inspired Alia Bhatt-starrer 'Raazi', revealed that Meghna Gulzar called him uncle during the filming, but wrote a nasty message to him after completion. "I don't want to speak to you anymore," she wrote to Sikka. "It took me eight years to write the book, and with one film...hard work was undone," said Sikka.
