Filmmakers Karan Johar and Ram Gopal Varma are known to take jibes at each other on Twitter every now and then. But this time Karan has gone a step further. In an exclusive interview to CNN-IBN, he's accused RGV of trolling him on Twitter. 'Ram Gopal Varma is the biggest entertainment of my life. He's basically a mad man. I think he has fits in the middle of the night. I think he is obsessively in love with me. He is like Shah Rukh Khan in the movie Darr. I want to tell him he was a great filmmaker and he should make another Satya,' Karan said.
