R. Madhavan, renowned for his recent performance in the film *Dhurandhar: The Revenge*, has unveiled a new poster for his upcoming biopic titled *G.D.N.* on Thursday. The poster features Madhavan's character engaging with a vast audience, capturing the essence of Gopalswamy Doraiswamy Naidu, an influential inventor often referred to as the 'Edison of India'. The tagline, 'Feared by the British... Forgotten by his countrymen', hints at the film's exploration of Naidu's emotional and historical significance. This biopic aims to shed light on the life of a man whose innovative spirit and contributions have shaped India's industrial landscape but remain largely overlooked. Directed by Krishnakumar Ramakumar and produced by Varghese Moolan Pictures in partnership with Tricolour Films, *G.D.N.* is set for a multilingual release across Tamil, Telugu, Kannada, Malayalam, and Hindi. The film is scheduled to hit theaters on July 17, 2026, promising to revisit the extraordinary journey of a pioneer whose legacy deserves renewed recognition.
