Heroine Nayantara is undoubtedly a big superstar in her own league. Though she couldn't pull a movie by completely herself, no doubt she's a big bet if coupled with another happening hero.Vijay Setupathi and Nayantara teamed up for "Naanum Rowdy Dhaan" which is directed by lyricist Vignesh Sivan. The film has a limited release initially, but the initial word of mouth and the fact that Nayan looked so fresh and hot in the film, have helped producer Danush a lot. "2.16 Crores for the first day is stupendous; screen count increase due to positive word of mouth", says Danush, for that reason. That's third hit in a row for Nayan after Thani Oruvan and Mayuri. That's true star power.
