R. Madhavan’s upcoming biographical film “G.D.N.” is presented as a cinematic account of inventor Gopalsamy Doraisamy Naidu, described across reports as the “Edison of India.” The Hindu highlights Madhavan’s long-standing interest in Naidu’s work and cites the actor’s motivation to bring the inventor’s life to the big screen, with the film directed by Krishnakumar Ramkumar and produced by Varghese Moolan Pictures. The release date is reported as August 7. Times of India describes the movie as tracing Naidu’s journey from modest beginnings to prominence in innovation, focusing on his major inventions as well as challenges he encounters involving governmental bodies. Both sources frame the film as a tribute to Naidu’s achievements and his impact, and they note early audience and review reactions that emphasize Madhavan’s performance and the film’s technical execution. Overall, the coverage aligns on the film’s subject, its biopic approach, and its planned release timing, while differing mainly in the emphasis placed on Madhavan’s interview versus audience and review commentary.
