Shah Rukh Khan on 'Chennai Express': "Rohit's films have a variety... comedy, drama, romance and action... everything. 'Chennai Express' is a comedy film with a love story, but it's definitely not like 'Kuch Kuch Hota Hai' or 'Dilwale Dulhania Le Jayenge'. It's a family entertainer. There's a little action too. It's something that whole family can sit down and watch together"
