Rocketry: The Nambi Effect

About the film

Rocketry: The Nambi Effect is a 2022 Indian biographical drama film written, produced, and directed by R. Madhavan in his directorial debut. The film is based on the life of Nambi Narayanan, played by Madhavan, a scientist at the Indian Space Research Organisation, who was accused in an espionage case and later exonerated. The story spans across Narayanan's days as a graduate student at Princeton University, before exploring his work as a scientist and the false espionage charges placed upon him. Simran plays the female lead.

After its official announcement in October 2018, principal photography took place across several countries, including India, Russia, and France. The cinematography and editing were handled by Sirsha Ray and Bijith Bala, respectively, while the original score was composed by Sam C. S. Rocketry was filmed simultaneously in Tamil, Hindi, and English.

Plot

The narrative is framed through a contemporary televised interview where aerospace scientist Nambi Narayanan recounts his career, along with the espionage charges that led to severe physical and psychological trauma for him and his family. The story flashes back to his early days at the Thumba Equatorial Rocket Launching Station, where he saves teammate A. P. J. Abdul Kalam from a severe laboratory injury. In 1969, Nambi receives a government-funded fellowship to pursue a master's degree in chemical rocket propulsion at Princeton University.

Under the tutelage of Professor Luigi Crocco, Nambi completes his degree and turns down a highly lucrative career offer from NASA, choosing instead to return to India to advance the Indian Space Research Organisation (ISRO). Despite successfully securing millions of pounds worth of equipment from Scotland for free, Nambi's research stalls following the sudden death of his mentor, Vikram Sarabhai, which leaves ISRO with depleted government funding. To circumvent this, Nambi negotiates a deal with the French scientific community to assist them with their liquid-propellant engine in exchange for technological access.

Nambi and his fifty-two colleagues covertly learn French before traveling but feign ignorance of the language to observe the French engineers. Upon discovering a critical design flaw in the French engine, Nambi leverages his team's expertise to fix the issue in exchange for the restricted testing data. Returning to India, the team spends eight years developing a prototype based on this technology. During validation trials back at the French facility, the engine safely withstands extreme pressure levels, proving to be a massive success. Nambi names the prototype the "VIKAS" engine in honor of Sarabhai.

Production

A film based on the espionage case of ISRO (Indian Space Research Organisation) scientist Nambi Narayanan was first announced to the media in September 2012 by director Anant Mahadevan. Journalist C. P. Surendran had proposed the idea for a potential film on Narayanan to Mahadevan during June 2012. The two then met Narayanan in person to discuss the idea and seek his permission, and he agreed to serve as a consultant for the project. Malayalam actor Mohanlal was cast in the role of Narayanan, while Resul Pookutty, Sreekar Prasad and L. Subramaniam were finalised as the sound designer, editor and music composer for the project. Titled The Witch Hunt, the film was to be made in the Hindi and Malayalam languages. The team were in talks with several production houses but the project eventually did not take off as planned. Mahadevan later narrated the idea of the film to actor R. Madhavan in the mid-2010s, who helped take the film forward.

Work on Rocketry: The Nambi Effect was first reported by Madhavan in the media during April 2017, when he announced that he was set to appear in a biopic featuring the "extraordinary story of an unsung hero", who was "neither an actor nor a sportsman". He called the project his "biggest film ever" and stated that he had worked silently on the script of the film for a period of two years after becoming intrigued by hearing the tale of Narayanan's false espionage charge. To develop the script and to provide a more factual account of the events, Madhavan regularly met with Narayanan, garnering his approval for the film and discussing the scientist's life experiences. As a result of their conversations, Madhavan chose to alter his original script to include portions from Narayanan's entire career and his services to the Indian space programme, rather than just matters related to the espionage case and his 1994 arrest. For the script, he also took inspiration from Narayanan's autobiography Ormakalude Bhramanapadham (2017) and Arun Ram's official biography of the scientist titled Ready To Fire: How India and I Survived the ISRO Spy Case (2018).

In October 2017, Madhavan confirmed that pre-production work for the film was underway and that he would portray Narayanan from the ages of 27 to 75, and that he was gaining weight to film the scenes featuring the older version of Narayanan first, after taking advice from Aamir Khan. Madhavan also announced that alongside his screenwriting and acting credits, he would also be one of the producers of the project. In regard to the making of the film, Madhavan stated that he hoped to differ in the script in comparison to other biographical films, and suggested that he would not call the film a "biopic" but an "incisive investigation into a brilliant mind and India's ambitious space technology". He also added that he felt that Madhavan was the "only Indian actor qualified to do this part" owing to his background as an electronic engineer with air-force training, and because he was "a thinking-actor who is also well-read". Madhavan was later announced as a joint director of the film.
