"I was thrilled, I was thrilled to bits to read each and every tweet, I waited for the next one actually. He is an exceptionally prolific filmmaker... I mean really that he gave me the importance for being the big tool to market his films, I think nothing could make me prouder," the 40-year-old said here at the launch of Filmfare magazine edition.
"I feel like the most important person on the earth, thank you. Secondly, I realised he is still alive, you know I really got worried for a moment because I thought we have lost him, so, I don't want such a great filmmaker to ever, ever leave us. So, I am so happy," Karan added.
When asked to comment on Ram Gopal Varma's film "Bhoot Returns", Karan said: "Oh, he is returning from where? I have already said he was alive. It's his debut, is it? 'Bhoot Returns'. I am not so sure."
"Bhoot Returns" released Friday.
