MUMBAI — Director David Dhawan, in his own words, is "over the moon." Why? Well, David is immensely proud of his son, Varun Dhawan,'s stellar performance in "Badlapur." For David, success of Badlapur is special as it has given a new identity to his son Varun, NDTV reported. "Today is a great day for me. I have seen so much of success till now but this success is at par and special for me," said David, known for hit films like "Raja Babu," "Coolie No. 1," "Saajan Chale Sasural" and "Haseena Maan Jaayegi." "Obviously he (Varun Dhawan) is my son but I think he has taken a very strong step to do a film like that. He has worked very hard on this film and it is evident also," the director said, adding that it was his own decision to do a dark and intense revenge drama. — SG
