Sai Pallavi who debuted in Malayalam and Telugu with Premam and Fidaa respectively is now making her Tamil debut with Karu (Kanam in Telugu) which is directed by Vijay and is said to be the story of a young single mother. Sai Pallavi said that the character she played was something she never experienced before. "I had a lot of support from Vijay sir. If your director knows what he wants on screen, it makes things easier. Vijay sir knew the exact emotion he wanted for a particular scene. I thought the mother-daughter scenes would work if they were a bit loud, but he asked me to play it subtle. When I watched the film while dubbing, I understood why he had said that," Sai Pallavi told in an interview.
