One of the biggest controversies in South Indian cinema involved Nayanthara and Dhanush, who had a legal dispute over a 3-second clip. The Lady Superstar criticized Dhanush for filing a civil suit against her after she used a brief clip from the film Naanum Rowdy Dhaan in her Netflix documentary. Since Naanum Rowdy Dhaan was produced by Dhanush, he claimed ownership of any material related to the film.
Dhanush filed a lawsuit against Nayanthara, her husband Vignesh Shivan, and their production company, Rowdy Pictures Private Limited, demanding Rs. 10 crore in damages. The legal battle caused a significant rift between the two prominent figures in South Indian cinema and sparked a major clash between their fanbases.
