Nawazuddin Siddiqui went through a tough time while preparing for his killer character in ‘Raman Raghav 2.0’. The actor says, “Without informing anyone, I left home for a couple of days. I feared myself while preparing for this role. In between, I was also hospitalized for a week. In an unconscious state I was talking about my scenes, while I had already shot for it. My wife called up Anurag Kashyap and asked what he had done to me.” For a detox from the intense film, Nawazuddin Siddiqui flew off to be with his family, “After completing the film, I went to my native place. I stayed there for 10-12 days. I returned to Mumbai only when I felt that everything was fine.”
