Nayanthara and Vignesh Shivan's lawyer has denied copyright infringement after actor-producer Dhanush sent the celebrity couple a ₹10 crore notice for using a clip from 'Naanum Rowdy Dhaan' in their Netflix documentary. "What has been utilised by us in the docu-series is not part of behind-the-scenes (from the film)...The same is part of the personal library," the lawyer said.
