Chennai, March 7 (IANS) Actor-choreographer Gayathri Raghuram is making her directorial debut with upcoming Tamil film "Yaadhumaagi Nindraai". She says filmmaking has been on her mind for a long time and didn't happen overnight."I didn't take this decision overnight. It's a dream I have been nurturing for a long time. After finishing my filmmaking course in the US, I also assisted Prabhudheva and director Vijay on a couple of projects. I have always wanted to direct," Gayathri told IANS.Talking about her film, which is due for release, she said it's about the lives of background dancers."It's about their lives and the struggles they face. It's partly based on real life incidents. Even though it's a women-centric subject, it's a story everybody can relate to. The story of some women dancers can be very inspiring," she said.Happy with the way the project has shaped, she said Dhanush's contribution has made it very special."He crooned a romantic number. It was so sweet of him to oblige to my request and sing. The film mostly features newcomers and I thoroughly enjoyed working on the project," she said.Gayathri herself plays a background dancer in the film.
