Filmmaker Ram Gopal Varma said audience in theatre was looking at each other after watching Abhishek Bachchan shake his head in strange way in 'Raavan'. "I called Abhishek and asked, 'What was that?'," Varma said, adding Abhishek explained that just like Ravan's 10 heads, he had ten thoughts running in his head and shook them off to stick to one.
