An all-out war has broken out between south cinema superstars Nayanthara and Dhanush over a three-second clip in a Netflix documentary.

Chennai: A legal dispute has erupted between South Indian film stars Nayanthara and Dhanush over a brief three-second clip in Netflix's upcoming documentary ‘Nayanthara: Beyond The Fairy Tale’.

Nayanthara and her husband, director Vignesh Shivan, have found themselves embroiled in a legal dispute with actor-filmmaker Dhanush. The controversy began when Dhanush filed a Rs 10 crore copyright infringement case after the trailer of Nayanthara’s upcoming Netflix documentary featured a 3-second clip from the film Naanum Rowdy Dhaan,

Naanum Rowdy Dhaan's film featured Nayanthara opposite Vijay Sethupathi. It was directed by Vignesh Shivan. Dhanush backed the film under the Wunderbar Films banner in 2015.

The legal clash escalated after Dhanush’s team demanded Rs 10 crore for the behind-the-scenes video, despite the couple’s two-year-long effort to secure permission to use elements from the film in their project.
