The film features a large ensemble led by Madhavan, with Sathyaraj, Priyamani, Jayaram and Dushara Vijayan among the prominent names. Only a handful of actor-character pairings have been officially revealed, so this guide clearly separates what is confirmed from what remains undisclosed.
R. Madhavan as GD Naidu
R. Madhavan plays Gopalswamy Doraiswamy Naidu, the Coimbatore-born inventor and industrialist whose work earned him the popular title of the Edison of India (India Today). The film dramatizes pivotal moments from Naidu's life rather than covering his entire biography, according to the film's official description on BookMyShow.
The trailer shows Madhavan across multiple stages of Naidu's life, from his ambitious younger years to an older version in which the actor appears almost unrecognisable (Asianet Newsable). Madhavan's involvement also extends behind the camera. He is credited on the screenplay and as one of the film's producers alongside his wife Sarita Madhavan under their Tricolour Films banner (Asianet Newsable).
Confirmed Characters in GDN
Only a small number of actor-character pairings have been publicly attached to the film. Here is every confirmed mapping, with some names drawn from the film's published credits.
| Actor | Character | Role Description |
|---|---|---|
| R. Madhavan | G.D. Naidu | The inventor and industrialist at the centre of the story |
| Sathyaraj | Ramiah Pillai | Named supporting character revealed ahead of release |
| Dushara Vijayan | Ranganayakiammal | Listed in the film's credits |
| Abdool Lee | Chidambaram | Listed in the film's credits |
| Carl Andrew Harte | Adams | Listed in the film's credits |
Sathyaraj plays Ramiah Pillai, one of the few named supporting characters revealed before the film's release (Cinema Express). The roles for Dushara Vijayan as Ranganayakiammal, Abdool Lee as Chidambaram and Carl Andrew Harte as Adams come from the film's published credits on Moviefone.

The Real Story: Who Was GD Naidu
To understand the cast list, it helps to know the man at its centre. Gopalswamy Doraiswamy Naidu was a self-taught inventor and industrialist from Coimbatore who helped shape India's industrial and technological progress. He is often credited with building India's first indigenous electric motor, yet his legacy remains largely forgotten, a gap this film aims to address (Asianet Newsable).
Rather than a cradle-to-career biography, GDN focuses on extraordinary true events from Naidu's life, testing his resilience and belief in progress against institutions and authorities that threatened his innovations. The official description calls it "an inspiring drama drawn from a remarkable chapter in the life of G.D. Naidu, legendary inventor, industrial visionary, and one of India's greatest innovators" (BookMyShow).
Creative Team Behind GDN
GDN is written and directed by Krishnakumar Ramakumar, whose previous directorial credit was Oho Enthan Baby (Cinema Express). The film is produced by Madhavan, Sarita Madhavan, Vijay Moolan and Varghese Moolan under Tricolour Films and Varghese Moolan Pictures.
The technical team includes:
- Music: Govind Vasantha, known for 96 and Meiyazhagan
- Cinematography: Aravind Kamalanathan
- Editing: Bijith Bala and K. Sasi Kumar
